Transcript
- 0:00Speaker 1: Joining me on the line is Nina Currency, director of
- 0:03Speaker 1: Medical entomology at the Center for Disease Control. Good morning to.
- 0:07Speaker 2: You, Nina, Yeah, good morning, Katie.
- 0:10Speaker 1: Nina. We're being told that mossies are expected to be
- 0:13Speaker 1: pretty bad from Monday. Events that could occur due to
- 0:16Speaker 1: weather this time of the year do make it perfect conditions,
- 0:20Speaker 1: of course, for mossi numbers to rise. Tell us a
- 0:22Speaker 1: little bit more about what to expect.
- 0:25Speaker 2: Yeah, So, obviously we had very high tides and quite
- 0:28Speaker 2: a bit of rain, so that means all the Salt
- 0:31Speaker 2: Marsh mosquito eggs are now inundated with water and they
- 0:34Speaker 2: will all hatch at once. So we are expecting an
- 0:38Speaker 2: influx of these mosquitoes hitting pretty much all along the
- 0:42Speaker 2: Northern Territory coastline, also Darwin, Palmerston rural areas. From Monday onwards.
- 0:49Speaker 2: There probably will be high numbers at least for the
- 0:51Speaker 2: next three weeks because of the humidity, they live long enough,
- 0:55Speaker 2: and unfortunately that also means that they're now able because
- 0:58Speaker 2: they've got enough time to pick up the Ross River
- 1:01Speaker 2: virus and potentially transmitted to people. So the high risk
- 1:06Speaker 2: period for Ross River is pretty much from December through
- 1:10Speaker 2: to March, and this is why we are urging people
- 1:13Speaker 2: to make sure not getting bitten by mosquitos, use thee
- 1:15Speaker 2: insect repellents and cover up with long sleeves and shirts,
- 1:19Speaker 2: and make sure that your kids when they're outside are
- 1:21Speaker 2: also adequately protected.
- 1:23Speaker 1: Nina, are there any suburbs which are going to be
- 1:26Speaker 1: more heavily impacted?
- 1:28Speaker 2: Yes, of any that are close to Salt marsh areas,
- 1:33Speaker 2: So we've got Leanya, Karama, all of those. Anything close
- 1:38Speaker 2: to the Casarina Coastal Reserve as well. But the department
- 1:43Speaker 2: has done extensive surveillance and control in those swamp areas
- 1:49Speaker 2: as well as in Darwin Urban itself and we have
- 1:52Speaker 2: treated close to two hundred and twenty five hectors of
- 1:56Speaker 2: high density breeding. But we know there's very large swamps
- 2:00Speaker 2: to the east of that area and these mosquitos can
- 2:03Speaker 2: fly up to fifty kilometers, so they will make their
- 2:06Speaker 2: way into Darwin suburbs and to all rural areas Palmerston
- 2:10Speaker 2: and along the coastline of course.
- 2:12Speaker 1: And Nina, what do we need to do to try
- 2:15Speaker 1: to protect ourselves?
- 2:17Speaker 2: So the best way is because these mosquitos, unfortunately by
- 2:21Speaker 2: day and night and they're pretty aggressive so the best
- 2:25Speaker 2: way is to use the insect repellent that contain deeed
- 2:29Speaker 2: o picarrodin. There's now an alternative around with oil of
- 2:34Speaker 2: lemon ucalyid also known as PMD that can be used.
- 2:39Speaker 2: And then just light colored long sleeved shirts, long pants
- 2:42Speaker 2: and socks, even though we all know it's hot, and yeah,
- 2:46Speaker 2: try to stay inside if it's really bad and if
- 2:49Speaker 2: you can, but as I said, there out day and night.
- 2:52Speaker 2: But if you use those precautions, that's probably your best protection.
- 2:56Speaker 2: And then there is mosquito lentns around you can buy
- 2:59Speaker 2: in any heart ware stores on normal supermarkets and they
- 3:02Speaker 2: also help a lot.
- 3:03Speaker 1: And Nina, I know that this is all obviously expected
- 3:07Speaker 1: from Monday, the increased number. How long are we expecting
- 3:10Speaker 1: it to last?
- 3:13Speaker 2: So pretty much we are predicting for the next three weeks. However,
- 3:18Speaker 2: if the weather is getting drier again and some of
- 3:20Speaker 2: these areas are drying out, then these mosquitos can lay
- 3:24Speaker 2: a lot of eggs again and then after the next
- 3:27Speaker 2: rain they will hatch again. So it really depends. If
- 3:30Speaker 2: it keeps raining, it should only be two to three weeks,
- 3:34Speaker 2: but yeah, otherwise this can reoccur and then obviously after
- 3:39Speaker 2: the first heavy mo monzoo, these mosquitos decrease in numbers.
- 3:43Speaker 2: But then you've got the common band of mosquitos that
- 3:45Speaker 2: are coming up, the freshwater breeders. They break continuously and
- 3:49Speaker 2: they also can transmit the Ross River virus as well
- 3:53Speaker 2: as Murray Valley encephalitis, which can be fatal. Yeah, but
- 3:57Speaker 2: those mosquitoes are active at night, so at the moment
- 4:01Speaker 2: they will be day and night. The other ones will
- 4:03Speaker 2: be at night. But having the opportunity, we would also
- 4:07Speaker 2: like to ask people to go into that backyard after
- 4:10Speaker 2: all this rain now and tip out everything that can
- 4:12Speaker 2: hold water and store it upside down out of the weather.
- 4:16Speaker 2: And that is because there's another mosquito that breeds close
- 4:19Speaker 2: to houses and that can also transmit ross through a
- 4:22Speaker 2: virus right into the backyard and chip out everything that
- 4:26Speaker 2: holds water.
- 4:27Speaker 1: Well, Nina, I tell you what, I'm always hoping for
- 4:30Speaker 1: the monsoon to arrive early, but I'm certainly hoping for
- 4:32Speaker 1: it now as well. After hearing that there's going to
- 4:35Speaker 1: be those increased Massie numbers and that year, if that
- 4:39Speaker 1: wet weather sticks around, it will sort of help to
- 4:41Speaker 1: keep those numbers down by the sounds of it after
- 4:45Speaker 1: this first lot, but really good advice as well in
- 4:48Speaker 1: terms of making sure that we tip out all that
- 4:50Speaker 1: water and just do all that we can to protect
- 4:53Speaker 1: ourselves from those pesky mossies.
- 4:56Speaker 2: Yes, and we also do have a salt marsh mosquito
- 4:59Speaker 2: past on our website and that tells people when high
- 5:03Speaker 2: numbers are expected. Also for twenty twenty.
- 5:07Speaker 1: Two, Well, Nina Kurtz, the director of Medical Entomology at
- 5:11Speaker 1: the Center for Disease Control. We always appreciate your time.
- 5:14Speaker 1: Thank you so much for having your chat this morning.
- 5:17Speaker 2: Thanks Katie, thank you,
