- 0:18Here we are in summer and we're in extreme heat advisories here in San Antonio
- 0:24and back on the the show is Dr.
- 0:26Tess Barton. She's our pediatric infectious disease expert.
- 0:31Tess, thank you so much for being back on Pediatrics Now.
- 0:34Thanks for having me. So I was in a clinic the other day and the pediatrician
- 0:40I was talking to, she said just that morning, it was noon when I was there,
- 0:44and she said she had had three families in with bug bites.
- 0:48And the parents were saying, you know, tell me what is it that bit my kid?
- 0:53And one of the families said that, and she said, well, I can't tell you that.
- 0:57And she's trying to answer all their questions and said, we're not experts on bug bites.
- 1:02So what advice do you have here for the busy pediatric practitioner now that we're in summer?
- 1:10Sure. So in the summer, the most common bug bites that we're going to see are
- 1:18going to be mosquito bites.
- 1:20But I think that when parents come in and they're worried about bug bites,
- 1:24maybe the thing that they are often worried about are bed bugs.
- 1:29And so I think for the pediatrician, there are a few little clues that you can
- 1:35use to distinguish bed bug bites from mosquito bites.
- 1:41So the most...
- 1:45Common findings for mosquito bites is that mosquitoes generally will bite you
- 1:49where you are exposed, right?
- 1:51So they're small, they're not strong, they don't have a lot of abilities to
- 1:57bite you through your clothes.
- 2:00So, you know, if your ankles, your arms, those places are exposed,
- 2:05those are the places where you will get bites.
- 2:09And, you know, mosquito bites can look very different from person to person
- 2:13because some people are very reactive to them and they will get these really
- 2:17big welts and some people are not, and they'll just get a little,
- 2:20you know, a little pink bump.
- 2:22Bed bugs, on the other hand, of course, they don't bite you when you are outside.
- 2:26They bite you when you are sleeping peacefully in your bed or on your sofa or
- 2:33whatever fluffy place that they happen to be living in.
- 2:38And bed bugs actually like to crawl around under your clothing as well.
- 2:48So they don't limit themselves to the places that are exposed.
- 2:52They also often live at the top of the mattress, underneath the top of the mattress.
- 2:58And so they will bite you on your face, whereas mosquitoes less likely bite you on your face.
- 3:05So if you are seeing large red bumps that are also in places that were covered
- 3:10by clothing and are scattered kind of all over the body or on the face,
- 3:15those are warning signs that that actually might be a bed bug infestation.
- 3:21So in that case, what are we supposed to do? And if anyone who's listening is
- 3:27having trouble sleeping, just skip this episode for now.
- 3:32We can talk about all sorts of other bugs, because there's other things and
- 3:36they each have a pattern.
- 3:38So you want to know what should they do if they suspect they have bedbugs? Yes.
- 3:44All right. So bedbugs are an insect that most commonly lives kind of on the
- 3:54underside of your mattress.
- 3:55And so they come out at night. So you may not ever actually see them crawling
- 4:01around because they burrow and they hide during the daytime. time.
- 4:06So if you feel them and it's the nighttime, you can turn on the lights really
- 4:10fast and sometimes catch them and see them.
- 4:13They vary in size. Most of them are just a few millimeters long.
- 4:20They look kind of just like a boring little gray bug.
- 4:24But the hallmark of finding them is that if you pull up the edges of the mattress,
- 4:29like lift the mattress and look on the underneath side,
- 4:32you know how like some mattresses have
- 4:35that little strip of piping along the edge
- 4:38you might have to like pull that to the side what you may see is you might see
- 4:43the bugs themselves but more commonly what you'll see is you'll see their poop
- 4:47and because they eat blood their poop actually looks like dried blood spots
- 4:52so if you're finding things that look like dried blood spots
- 4:56clustered on the underside of your mattress, that's the telltale sign of bedbugs.
- 5:03So the first thing is...
- 5:05Get rid of the mattress? Yeah, I mean, so you probably, you know,
- 5:10there are many different ways of that have been tried for dealing with bed bugs.
- 5:16Ultimately, getting rid of the mattress is the most effective.
- 5:20But you also have to usually treat the home or the room as well,
- 5:26because they could be hiding in other places, and then they'll just set up shop on your new mattress.
- 5:32So we recommend any
- 5:37pillows or beddings or cushions that can be physically washed in the dryer should
- 5:47be washed on hot water and dried in high heat to really kill them off.
- 5:53The other thing that you can do is if it's something too large or bulky to put
- 6:00in the washer and the dryer, like your sofa or a large pillow,
- 6:07that you can wrap them up in a black plastic bag and ideally place them in the sun where it's hot.
- 6:18But wrap them up in a black plastic bag for a couple of weeks,
- 6:22because that actually allows,
- 6:25it traps the bugs, they can't get out, and they will cycle through their life
- 6:31cycle and any eggs that they have laid will hatch, but they won't have anything
- 6:35to eat, and then they will die.
- 6:39People will often do, you know, like a bug bomb, right, like an insect bomb in the house.
- 6:46And you can get permethrin sprays and spray, you know, spray your sofa,
- 6:52spray the undersides of things.
- 6:54But in general, if it can be if there's toys or cushions or beddings, you want to wash them.
- 7:01And then be vigilant and keep an eye out for them returning.
- 7:04Sometimes bed bugs can be very very persistent.
- 7:09And Tess, or Dr. Barton, do we need to worry about bedbugs or even think about
- 7:15them if we haven't been traveling recently?
- 7:18Sure, sure. We have plenty of bedbugs in Texas. So people do pick them up,
- 7:22you know, often when they are on travels and they stay in a hotel and the bedbug
- 7:26stows away in their luggage and then finds a new home.
- 7:30But it's also possible for your, you know, neighbors to have bedbugs and they
- 7:36come over visiting your house.
- 7:37Not the neighbors the bugs so then they can leave the bugs when they leave no
- 7:43like the neighbors don't bring the bugs the bugs take a journey they come walking
- 7:47over oh seeking out new new new housing ah like walking through the grass and everything yes.
- 7:59Speaking of grass there's also tons of other bugs that you can get in the grass,
- 8:03so so well before we move on so with the bed bugs can they be harmful or make
- 8:10us sick or make children sick no generally they don't make you sick they there's i don't,
- 8:18know of any diseases that I can think of off the top of my head that are transmitted by bedbugs.
- 8:23There are diseases that are transmitted by lice and fleas and mosquitoes,
- 8:28of course, but I don't know that bedbugs actually transmit any diseases.
- 8:33But they are miserable. Like the bites of bedbugs are extremely, extremely itchy.
- 8:41And so people who have those bites are pretty miserable for several days.
- 8:46So what do you recommend for kids? What should the parent do if they are bitten?
- 8:52Yes. I mean, to treat bed bug bites, it's the same kind of grandma medicine
- 9:00that we use for other types of bites.
- 9:03You can use calamine lotion and antihistamines like Benadryl.
- 9:09You can do you know oatmeal
- 9:12baths things that help to dry
- 9:16them up do you recommend benadryl cream
- 9:19you can use benadryl cream but you shouldn't use benadryl cream and benadryl
- 9:25by mouth together because you do absorb some when you put cream on so you can
- 9:29also use hydrocortisone cream or other you know steroid anti-itch creams to
- 9:35to help with those and just follow what it says on the.
- 9:39Tube. Yes, yes.
- 9:42So, and I know you're a world traveler.
- 9:46Do you keep your suitcase not on carpet when you travel for this reason?
- 9:50Or is there anything you do as a lot of us are heading on summer vacations?
- 9:54Yes. So I actually had a bed bug experience when I went to Laos.
- 10:04And I had, It was sort of the very busy New Year's time, so there were limited hotel rooms.
- 10:11And we had booked a hotel for a few days. And...
- 10:17We're peacefully sleeping in the bed when suddenly I felt, I felt things crawling
- 10:24on me and I freaked out and flipped the lights on and started looking.
- 10:31And I found, I saw the bugs and I immediately packed up my luggage and threw it out of the door.
- 10:39And it was two o'clock in the morning and we were like, we're not staying here.
- 10:44And of course, like it was a small town.
- 10:47It wasn't like a big city where things are open 24 hours and had to like walk
- 10:51around looking for another hotel where there was somebody at the desk.
- 10:56And when we finally found one and we told them like, oh my gosh,
- 11:00we were at this other place and there were bugs. You can't bring your things in here.
- 11:06And they put our things outside.
- 11:11And in the morning, right on the street, because it was like right at the street
- 11:15with a little plaza in front of everybody, we had to like unpack our luggage,
- 11:19spray everything down with tons of tons of, you know, insecticide spray.
- 11:25We did find one bug in the luggage. Oh.
- 11:57That are the bed bug poop because I never, ever want to deal with that again.
- 12:03Wow. So you do that every time, but that makes sense. And what were you saying
- 12:09about smelling smoke, smelling for smoke?
- 12:11Well, I just don't like smoke in the room. If someone had been smoking. Exactly.
- 12:18So that's really smart. And then do you keep your luggage not on carpet for
- 12:2324 hours when you get back or do anything like that?
- 12:26No, I don't usually do that. If I see any evidence of bed bugs,
- 12:33I just don't stay at the place.
- 12:34Do you look at all parts of the underside of the mattress or just one corner?
- 12:40Would they be in all corners or can you tell us about that i usually look at
- 12:44the top the two top corners up by the headboard because that's the most common
- 12:49place where they cluster yeah.
- 12:51Have you found any yet hopefully not no yeah okay and did that ruin your trip
- 12:59to laos it did not it did not it was we had an amazing trip i was actually yeah
- 13:05we were actually in in the process of moving there when this happened.
- 13:09So, yeah, so no, it was, it was fine, but it did, it, you know,
- 13:14it did, it did make me very wary of, of, of,
- 13:19of places of hotels so how
- 13:23long did you live in Laos and what were you doing there I lived
- 13:27for a year in Laos and I was there's
- 13:30a little children's hospital that is sponsored by
- 13:33a non-profit organization in a town called Luang
- 13:36Prabang which is a UNESCO world heritage site it's a really lovely town with
- 13:42the sort of highest concentration of Buddhist temples in the world and and so
- 13:49I was volunteering at a little hospital doing pediatric work. That sounds amazing.
- 13:55That's wonderful. Well, thanks for sharing that story with us.
- 13:58So, shall we move on to mosquitoes?
- 14:02When should we worry about mosquitoes? What do you do to protect yourself against mosquitoes?
- 14:09Do you use any kind of spray or is it mostly clothing?
- 14:13So, yeah, we should worry about mosquitoes. Mosquitoes are the most dangerous
- 14:17animal in the world, right?
- 14:19Yeah, they kill more people than any other animal. Wow, I did not know.
- 14:25Because they transmit a variety of diseases. So luckily, you know,
- 14:30here in the US, we don't have many of those diseases.
- 14:34You know, we don't have malaria and yellow fever and dengue,
- 14:38at least not much dengue.
- 14:40So we don't, you know, we don't have to worry as much about mosquito-related
- 14:45diseases, although we do have some.
- 14:47But yeah, mosquitoes are more an annoyance than anything else.
- 14:52But it is a good practice to try to avoid them.
- 14:56So again, as I mentioned, they
- 14:57usually don't bite through clothing because they're not strong enough.
- 15:03So long sleeves, long pants, protective clothing is a good all-purpose way to
- 15:09protect yourself from mosquito bites.
- 15:11And then yes, I do use insect repellent.
- 15:14I unfortunately have to use insect repellent like every day when I go out in
- 15:18my garden to do anything because it's mosquito land.
- 15:23And so for myself, I prefer to use a DEET containing repellent,
- 15:30usually around a 30% DEET.
- 15:33For children, we recommend that children under two months shouldn't use insect
- 15:38repellent. they should use protective clothing.
- 15:40Children over two months, the AAP does recommend that they can use insect repellents,
- 15:46but they need a lower, they should have a lower concentration. So the.
- 15:52So if it's a DEET-containing repellent, they recommend a 10% DEET product,
- 15:59and that will give about an hour and a half of protection against mosquitoes.
- 16:04So you do have to reapply it if you're going to be outside for longer than that.
- 16:08Although when it's a billion degrees outside, I can't imagine why anybody wants
- 16:11to be outside that long. Right, exactly.
- 16:14And do you, again, follow the recommendations that's on the container for children?
- 16:22I do. I do. But it can be very confusing, right?
- 16:25Because they also have a list of ingredients and it's hard to know what's the best one.
- 16:32And a lot of people don't want to use DEET, right? It's a chemical and we do
- 16:36absorb it into our system a little bit. About 10% of it we absorb into our system.
- 16:41And so a lot of parents prefer something that's more natural.
- 16:44And there are there are some
- 16:47alternatives but i think parents need to be aware of
- 16:51kind of the pros and cons of those different things there are
- 16:56you know there's all sorts of like citronellas and oil of lemon eucalyptus and
- 17:02and a variety of like essential oils rosemary oils and things like that that
- 17:08are in if you look at like the you know like the skintastic for kids or whatever
- 17:13It has those kinds of things in them.
- 17:17And there have been comparative studies looking at how well those work compared
- 17:22to DEET and other things.
- 17:23And they are not as effective as DEET.
- 17:27They also, because they are natural plant-derived oils or plant-derived products,
- 17:33sometimes people are actually sensitized to them and they can have like skin
- 17:37reactions to those products.
- 17:40So, you know, it doesn't mean that you can't use them.
- 17:43It just means that you have to anticipate that they may not be as effective
- 17:46and be on the lookout for the potential for skin reactions.
- 17:51So, and the pros and cons. So, for you, where you use DEET, it's more important
- 17:59to avoid the potential harm a mosquito could cause.
- 18:02Can you tell us about that? Well, sure.
- 18:05So, I mean, you know, like I said, here in the U.S., where we don't have as
- 18:11much of an issue of mosquito transmitted diseases, we do have,
- 18:16most commonly, we do have West Nile virus.
- 18:18There are some other viruses that mosquitoes transmit that can cause some serious
- 18:26infections, but they're pretty rare, right?
- 18:29So it's unusual to get a mosquito bite that then leads to some sort of disease
- 18:35here in the U.S., but it's not unusual elsewhere in the world.
- 18:39So little travelers, for sure, should be protecting themselves against mosquitoes.
- 18:45And that's a whole separate issue of bed nets and things like that if you're
- 18:50going to be doing international travel.
- 18:52But here in the U.S., it's really just, you know, doing your best to avoid the
- 18:55bites so that, you know, you don't scratch it like crazy and get impetigo or
- 19:00something to avoid the annoyance and the,
- 19:04you know, the infections that we cause from our fingernails from messing with our itchy skin.
- 19:12So what was your question again? So, and Tess, Dr.
- 19:17Barton, and I'm saying both because I'm going for the parents episode, I'll change it to Dr.
- 19:21Barton and the pediatrician one, I say Tess, but because we have two podcasts
- 19:25now, but I'll edit this out.
- 19:27And we will have for our pediatric practitioner listeners, we will,
- 19:31our sister podcast is Pediatrics Now for Parents.
- 19:33So you can tell your patients, your families that who come to see you,
- 19:37they could go to Pediatrics Now for Parents, the bug bite episodes so that you
- 19:42don't, hopefully it's one less thing you have to say in the exam room.
- 19:45You can say this is in more detail on Pediatrics Now for parents,
- 19:49wherever you get podcasts.
- 19:51So we were talking about some mosquitoes.
- 19:55Do you think, A, DEET is okay for kids, or is there anything more you want to
- 20:00say on that? And B, when should we worry about mosquito bites?
- 20:04So, yeah, so I think I answered kind of when we should worry about mosquito
- 20:09bites, which is we don't usually have to worry about the health consequences
- 20:13of mosquito bites here in the United States, but we should worry about them when we're traveling.
- 20:18As far as is DEET safe for children? Yes, DEET has been shown to be safe for children.
- 20:25And we do prefer to give a lower concentration because we know there can be some absorption.
- 20:34There are 100% DEET products that are available at outdoors stores.
- 20:42Stores, there's really no reason why anybody needs 100% DEET other than you
- 20:48want to feel macho about your mosquito repellent.
- 20:50But that is too concentrated for children.
- 20:55For parents who want a more natural approach, the next best alternative is a
- 21:01product called oil of lemon eucalyptus,
- 21:04which is a tree with an oily leaf that has a citrusy kind of smell.
- 21:13And there was actually a very interesting comparative trial looking at a variety
- 21:22of different mosquito repelling methods.
- 21:24And the oil of lemon eucalyptus was around the same effectiveness as DEET.
- 21:32And so it is a good, it is a good alternative for parents who are looking for
- 21:36a more natural, less chemical solution.
- 21:40Product for an insect or talent. And with epitaigo, is that you scratch it too
- 21:47much and then there's bacteria under the nail or something? How does that happen? Exactly.
- 21:52So, epitaigo is caused either by staph, a common skin bacteria,
- 21:57or by group A strep, which is a common throat bacteria.
- 22:01And so, you basically scratch the skin.
- 22:05You know, as long as bacteria are sitting on a surface of your skin and not
- 22:08in your skin, They don't really cause you a problem, but if they get to where
- 22:13they don't belong, that's when they begin to cause an infection.
- 22:15And so then you can get impetigo.
- 22:18And that can be, you know, that can be not only very, you know,
- 22:24painful and scarring, that can sometimes turn into a bigger infection or have
- 22:30some of the consequences of, you know, strep infections.
- 22:33But yeah, so that's really the main issue with mosquitoes here.
- 22:38We have not had any human West Nile in Texas this year, although mosquitoes
- 22:45have tested positive, including mosquitoes in Bexar County.
- 22:48Hmm. Wow. But that just means luckily it isn't happening.
- 22:53Is it going to happen this summer, do you think? I don't know.
- 22:57So the health department does these like sentinel screenings.
- 23:02So they have mosquito pools, like collections of mosquitoes,
- 23:07which sounds like the grossest thing ever.
- 23:10And they have what are called sentinel chickens that are these like coops of
- 23:15chickens that they test periodically and horses.
- 23:19So they test sort of the other animals that can carry this virus.
- 23:26And so the mosquitoes have tested positive. But
- 23:29typically what happens when they get a positive test is the health department
- 23:34actually will normally do some sort of like regional or local spraying in the
- 23:43area where those mosquitoes have tested positive.
- 23:48So that we don't have, you know, diseases. And that's been effective.
- 23:52We have really only a handful of West Nile cases each year.
- 23:58For families, you know, there are mosquitoes breed in water and in wet wood.
- 24:05And so anything where there's a pooling of water that's not regularly flowing
- 24:12is where you'll find the little mosquito, wiggling mosquito larvae.
- 24:17So in your like potted plants and if there are, you know, tires or other things
- 24:24that are in your yard that have gotten, you know, rain in them,
- 24:28and they have a little puddle of water, that's a place where mosquitoes will breed.
- 24:35And so, you know, in your own household, making sure that you've,
- 24:40you know, turned, dumped the water out after rains.
- 24:45And that you don't have standing water, that, you know, that you've got a cistern,
- 24:49like a rain cistern or a pool or something.
- 24:52I mean, pools should be circulating, but, or a fish pond, you know,
- 24:56like those kinds of things should be, they either need some kind of circulation
- 25:01system so that the water's not stagnant or they need to be covered.
- 25:04So the mosquitoes don't get in them.
- 25:06That's great advice. And with the impetigo, if it's swelling,
- 25:10it looks like an infection, it's red, what do you do from there?
- 25:13So, yeah, so impetigo will look like, Like, you know, usually a red,
- 25:18swollen, painful, crusty, oozy little lesion. It's kind of round and raised.
- 25:28In Haiti, they call them boutons, which means buttons. So imagine a button on the skin.
- 25:35And, yeah, and so usually that can be treated if they're early.
- 25:39They can really just be treated with a topical antibiotic ointment,
- 25:44cleaning them, you know, cleaning them well, keeping them dry and treating a
- 25:49little topical antibiotic is usually enough.
- 25:52If there's a ton of them, or if they have a larger zone of redness around them
- 25:59where they're causing kind of a larger skin infection,
- 26:02then that might need systemic antibiotics, right? So antibiotics that you take by mouth.
- 26:08My last question about mosquitoes, I was reading in the Washington Post that
- 26:12when we breathe out, it's basically telling the mosquitoes that we're there
- 26:17and we can be like this giant protein shake for them that's very attractive.
- 26:24And but do we build up, you know, like over time, the bites may not show up
- 26:30on our skin because we're not getting that reaction.
- 26:32We have an immunity to the reaction, but we still would could are we still exposed
- 26:36to the potential danger or what do you say about that?
- 26:40Yeah, that's actually a great question. So, you know, there are mosquitoes are
- 26:45attracted to a variety of chemicals that we, you know, that we exude.
- 26:51And some people are kind of more mosquito magnets than others.
- 26:56And actually, people who eat a lot of garlic naturally repel more mosquitoes than other people.
- 27:06Maybe that's a wives' tale. I don't think it's a wives' tale, though.
- 27:09And that's part of the basis of the vampire myths.
- 27:16Yes. And, and so, yeah, but, but, but many people will report the experience
- 27:22of, you know, at the beginning of the mosquito season,
- 27:25you know, in the spring after it's been raining a bunch and the mosquitoes have
- 27:29suddenly been breeding and it's starting to warm up, you'll get like 1 million bites when you go out.
- 27:35And then, you know, after a month or so, you just don't get bitten anymore. Right.
- 27:40And I always joke around that when that's happened to me, that it's like the
- 27:44mosquitoes can smell that I'm like all used up and they're not fresh anymore. They don't want that.
- 27:51But really, it's much more likely that what happens is our immune systems get
- 27:56reminded about the mosquito saliva.
- 28:01And, you know, while we initially have a little allergic response,
- 28:04which is what makes the the little itchy spot, we get desensitized after repeated
- 28:10exposures so that we're just not as allergic to their saliva anymore.
- 28:14So they may be that they're still biting us, but we are just not responding
- 28:18to those bites the way that we did initially.
- 28:21And do we need to not worry about getting one of those rare diseases then too? No, not usually.
- 28:32If there's an outbreak, then yeah.
- 28:36If there's suddenly on the news that several cases of West Nile have been reported,
- 28:42then yeah, I would be a little bit more robust about mosquito avoidance.
- 28:46But for the most part, I mean, it is quite rare.
- 28:49So really, it's more for mosquitoes in the U.S., more of an annoyance than they are truly dangerous.
- 29:01Do you recommend once it seems like the mosquitoes are not biting you,
- 29:05still put the DEET on or can we stop them?
- 29:09You know, there are mosquito seasons. So actually, when it gets super,
- 29:13super hot, it's too hot for the mosquitoes.
- 29:15They don't want to be out either. They want to hide in their nice, cool spaces.
- 29:19So I think that you can see sort of how often are you getting swarmed by mosquitoes
- 29:26when you go out and decide if you want to use the deed or not. Okay. And so...
- 29:37So say there's a child who comes into the pediatrician's office and there's
- 29:40a bite and it doesn't seem to be a mosquito. Like, number one, it's likely a mosquito.
- 29:47Then look at what you're saying. Look at maybe it's bed bugs.
- 29:51If there's you described what to look for, then what next would you say?
- 29:55What else should we be concerned about?
- 29:58Well, we have a lot of biting critters here in Texas. So biting and burrowing
- 30:05and blood-feasting creatures that like us.
- 30:11So there are other common things that are biting or getting on our skin are fleas.
- 30:22And there's also chiggers which is a mite that lives in the grass similar to
- 30:27chiggers is scabies which is another mite that you usually get from contact with another person,
- 30:34there of course are things like spiders so spiders will absolutely bite you
- 30:39if you if you have put yourself in their way so you know i think it for the
- 30:45pediatrician you know the usually the way to to figure out what's been biting the child is,
- 30:53where's the bite located?
- 30:56What were they doing when they were bitten? And obviously, did they see the thing? That's helpful.
- 31:04Yeah, one pediatrician was saying to me, like, family was saying,
- 31:07well, what bit my child? And she was saying, well, I can't tell you.
- 31:10I don't know. I wasn't there.
- 31:11She was trying to, you know, can you tell me more information? Right.
- 31:15And some things are not bites. Some things are also stings, right?
- 31:18So scorpions and wasps and bees, those are actually stings and not bites,
- 31:23but they will cause a, you know, a painful lesion, swollen spot.
- 31:28Is there some of the ones you just listed? Do you want to mention some telltale
- 31:32signs or is there a website you recommend?
- 31:34Because it almost seems like it can be overwhelming in that short time you have
- 31:38in the exam room and you're trying to help this family and this child and to
- 31:42not, you know, to have to try to figure out what is this bite.
- 31:46I actually will mention healthychildren.org.
- 31:50I'm not sure that there's a lot of information about distinguishing different
- 31:54bites on there, but there's actually good information about repellents and dealing
- 31:59with bites on that website.
- 32:01So it's a handy website for parents to have. So I think that maybe the one that
- 32:10I will mention are fleas.
- 32:14So fleas, of course, we commonly associate them being on our household pets,
- 32:21but fleas are not limited to our household pets.
- 32:26Fleas live very abundantly on the backyard wildlife.
- 32:32So the possums and squirrels and even birds and things that are in our yards.
- 32:39And they will get in our grass. So sometimes there can be flea infestations in your grass.
- 32:49And I mentioned that because, you know, what happens is your dog goes outside to go potty and,
- 32:58you know, maybe it picks up a flea or something that was on a possum and then
- 33:01it comes back in and that flea jumps around and it bites you.
- 33:06One of the ways you can tell if you have a flea infestation in your grass is
- 33:11that fleas jump and bite, but they don't jump super far.
- 33:16So they usually jump all over your
- 33:18ankles. And they bite your ankles like crazy, but not the rest of you.
- 33:23So if you have a bunch of little tiny, tiny spots, pink, itchy spots on your ankles.
- 33:35There can be other things as well, but sometimes that should prompt a concern for fleas.
- 33:42And fleas are important in our part of Texas, actually, because fleas do transmit
- 33:47disease called murine typhus.
- 33:50And we actually have a lot of
- 33:51that in San Antonio. And that can be pretty serious and pretty dangerous.
- 33:57And so doing flea control is actually pretty important.
- 34:03And murine typhus, if you suspect a child has that, what do you do then?
- 34:08Well, so murine typhus is an illness where the fleas have a bacteria called
- 34:15Rickettsia typhi, and they transmit that bacteria to you when they bite you.
- 34:20And that bacteria gets into your bloodstream, and it swims around,
- 34:23and it causes a lot of inflammation in your blood vessels, and it can cause
- 34:31inflammation in your brain and in your heart.
- 34:34So it's actually a pretty serious illness.
- 34:37Usually it's a fever illness. So people who have a fever that's been going on
- 34:41for more than a few days, right? So usually if you have a fever, like, oh, it's a virus.
- 34:45But if it seems like it's going on a little bit longer, or if it has a...
- 34:51A rash, a fever and a rash with headache or stomach aches, things like that,
- 34:57those should raise a little bit of a suspicion for typhus.
- 35:03We've had a significant increase in typhus cases in the San Antonio area for the past 10 years or so.
- 35:12So it's actually becoming fairly common here and it is transmitted by fleas.
- 35:18Can you treat it with antibiotics?
- 35:20Yes, it is treated with an antibiotic
- 35:22called doxycycline, which is not the most fun antibiotic to take.
- 35:26It's got some side effects, but it would be better to avoid getting typhus in the first place.
- 35:31The adage, prevention is the best medicine. Yes, exactly.
- 35:36Dr. Tess Barton, thank you so much for being back on Pediatrics Now today.
- 35:42I really appreciate it. Thanks. It was lots of fun.
- 35:46Music.
