Latest / 360 with Katie Woolf / Director of Medical Entomology with NT Health Nina Kurucz says cases of Japanese Encephalitis are on the rise in the NT...here's what you need to know
Transcript
- 0:00Speaker 1: You're listening to Mix one O four nine. Now, Northern
- 0:02Speaker 1: Territory residents and visitors are being reminded to protect themselves
- 0:07Speaker 1: from mosquito bites following an increase in the number of
- 0:10Speaker 1: feral pigs that have tested positive to Japanese in cephalitis
- 0:14Speaker 1: in the top end. Now, joining me on the line
- 0:17Speaker 1: to tell us a bit more about this and what
- 0:19Speaker 1: it means to Territorians is Nina Kurtz, the director of
- 0:23Speaker 1: Medical entomology with nt Health. Good morning to you, Nina.
- 0:28Speaker 2: Yeah, good morning to you too.
- 0:30Speaker 1: Now, Nina, what exactly is Japanese in cephalitis.
- 0:35Speaker 2: Japanese encephalitis is an inflammation of the brain, So when
- 0:40Speaker 2: people contract the disease there will be in your neurological signs.
- 0:45Speaker 2: So it's a very serious disease which can include se
- 0:50Speaker 2: be a headache and fever, seizures and fits, next disiness, drowsiness, confusion.
- 0:57Speaker 2: It can also lead to coma and in some cases,
- 1:00Speaker 2: unfortunately also to death, and we had a case early
- 1:05Speaker 2: last year. Fortunately we haven't had any cases since compared
- 1:10Speaker 2: to all the cases on the East Coast, and that
- 1:14Speaker 2: is probably because on the East Coast they have these
- 1:18Speaker 2: huge commercial piggeries with thousands of pigs and pigs sort
- 1:23Speaker 2: of domestic picks as well as well as feral pigs.
- 1:27Speaker 2: They act as what we call amplifiers, so they can
- 1:30Speaker 2: have a lot of virus and morsitos can pick up
- 1:33Speaker 2: the virus and then transmit the disease to people.
- 1:37Speaker 1: Right. So, Nina, at this point in the top end,
- 1:39Speaker 1: we've just had one case in a human, is that correct?
- 1:45Speaker 2: Yeah, and that case occurred early last year, so we
- 1:48Speaker 2: had a whole year without a case, which is great.
- 1:51Speaker 2: But we know from forty four feral pigs that have
- 1:55Speaker 2: tested positive from surveys that the Northern Australian Quarantine Strategy
- 2:01Speaker 2: did just recently, that the virus is in the environment.
- 2:05Speaker 2: We know that the mosquitos that can transmit the virus
- 2:09Speaker 2: is getting up in high numbers now. So again we
- 2:14Speaker 2: are asking people to protect themselves from mosquito bites, use
- 2:18Speaker 2: the repellents as an alternative out now called oil of
- 2:21Speaker 2: lemon nucalyp otherwise, or the repellents contain indeed or picarried
- 2:26Speaker 2: in long sleeved shirts, long pants, and make sure your
- 2:29Speaker 2: kids are also protected.
- 2:31Speaker 1: So, Nana, can you talk us through exactly how it
- 2:34Speaker 1: spreads what's the situation here.
- 2:38Speaker 2: So there's some ard eyed birds, which are your herons
- 2:42Speaker 2: and egrets. They can have the virus, so the mosquitos
- 2:46Speaker 2: can pick it up from the bird and then also
- 2:51Speaker 2: give it to pigs. So in our case, mostly the
- 2:54Speaker 2: feral peaks, and they then amplify the virus. They work
- 2:58Speaker 2: up a lot of virus, and then mosquitos can pick
- 3:01Speaker 2: it up from there again and transmitted to humans. So
- 3:05Speaker 2: you've got high risk situations close to waterways up to
- 3:09Speaker 2: five kilometers from the big wetlands, where you've got the
- 3:13Speaker 2: feral pigs, you've got the water birds, and you've got
- 3:15Speaker 2: the mosquitos. Fortunately, those mosquitos are only active after some
- 3:20Speaker 2: down so when people are out and about at night,
- 3:24Speaker 2: just use the mosquito repellents and protect yourself from getting bitten.
- 3:27Speaker 2: That's the main thing at the moment.
- 3:29Speaker 1: Yeah, absolutely, and so is the biggest concern here, people
- 3:33Speaker 1: that are maybe out hunting or fishing or out camping
- 3:37Speaker 1: in some of those areas where there can be feral
- 3:39Speaker 1: pigs around, and also those birds.
- 3:42Speaker 2: Yeah, absolutely, they are the high risk group of people,
- 3:46Speaker 2: of course, but also people who live in rural areas
- 3:49Speaker 2: and who might be wandering outside their property after some downs.
- 3:53Speaker 2: So they also have been very careful people in communities
- 3:56Speaker 2: who live very close to wetlands. So there's a lot
- 3:59Speaker 2: of people potentially at risk after sundown in the Northern Territory.
- 4:04Speaker 1: Nina, you did mention that obviously, protecting yourself from mozzies,
- 4:09Speaker 1: I mean it is a mosquito born virus. Protecting yourself
- 4:12Speaker 1: from those mosquitoes is the best plan of attack here.
- 4:16Speaker 2: Yes, it absolutely is at the moment, and anti health
- 4:19Speaker 2: is also at the moment working up a vaccination strategy
- 4:24Speaker 2: so to trying to figure out, taking all those risk
- 4:28Speaker 2: factors into account, which group of people are mostly at risk,
- 4:32Speaker 2: and then the vaccination will be rolled out to those people.
- 4:36Speaker 2: But until that happened, as we say, just protect yourself,
- 4:41Speaker 2: use the repellen, put on the light color clothing, long sleeves,
- 4:45Speaker 2: long pants, and if you can avoid mosquito prone areas
- 4:48Speaker 2: at night.
- 4:49Speaker 1: And so Nina, are we we're working on a vaccine
- 4:53Speaker 1: now this for this disease. How far away do you
- 4:56Speaker 1: reckon it could be?
- 4:58Speaker 2: So there is a very say vaccine available already. Unfortunately,
- 5:03Speaker 2: because Japanese encephalitis is new to Australia, there's only a
- 5:09Speaker 2: limited supply of vaccines at the moment, so therefore we
- 5:13Speaker 2: are trying to work out at the moment which groups
- 5:17Speaker 2: of people are mostly at risk to make sure those
- 5:20Speaker 2: people can be vaccinated first until further vaccines become available.
- 5:25Speaker 2: And this is what anti health is working at at
- 5:27Speaker 2: the moment.
- 5:28Speaker 1: Now, Nane of this may be a stupid question, but
- 5:30Speaker 1: what does it mean ultimately, I mean for pigs and
- 5:33Speaker 1: ultimately the consumption of PORLK. Does it have an impact
- 5:36Speaker 1: in that? Why not?
- 5:39Speaker 2: At all? Consumption of park is absolutely safe. Unfortunately, the
- 5:45Speaker 2: pigs themselves as well as horses and humans can get sick.
- 5:51Speaker 2: And the Northern Australian Quarantine Strategy and Department of Industry,
- 5:55Speaker 2: Chism and Trade and Health we are all doing our
- 5:59Speaker 2: part in surveillance of mosquitos and feral pigs to figure
- 6:04Speaker 2: out the risk. But park consumption is safe.
- 6:07Speaker 1: And Nina just finally, obviously since March twenty twenty two,
- 6:11Speaker 1: so earlier this year, with those forty four feral pigs
- 6:14Speaker 1: that have been infected, what area have they been in?
- 6:17Speaker 1: What region?
- 6:20Speaker 2: They have been found in several regions and they include
- 6:23Speaker 2: the Victoria Daily, the Cox Daily, the litchfield Shire, Teewe Islands,
- 6:28Speaker 2: the Marachai Douctlas daily and also recently we detected it
- 6:32Speaker 2: in West Arnam and there will be further surveillance done
- 6:37Speaker 2: to the east very shortly by the NAKs team and
- 6:42Speaker 2: that will inform us further about the risk and where
- 6:45Speaker 2: the virus might be. Just to put it in perspective though,
- 6:49Speaker 2: we also are testing the mosquitoes who we've tested up
- 6:52Speaker 2: to fifty thousand mosquitos already and we have not found
- 6:56Speaker 2: the virus in any mosquitos today via PCR tests, but
- 7:01Speaker 2: again this work will continue. Next year, the pic testing
- 7:04Speaker 2: will continue and hopefully a lot of vaccine will be
- 7:08Speaker 2: shortly available for people in the Northern Territory.
- 7:12Speaker 1: Well, Nina, we always appreciate your time, but really appreciate
- 7:15Speaker 1: you are giving us a bit more detail about Japanese
- 7:17Speaker 1: in cephalitis this morning. If there is anybody listening who
- 7:21Speaker 1: is concerned and thereafter a bit more info, can they
- 7:24Speaker 1: head to the Anti health website?
- 7:26Speaker 2: Yeah, absolutely, and they can contact Anti Health or Medical
- 7:31Speaker 2: Entomology or the Department of Industry, Tourism and Trade for
- 7:34Speaker 2: further information. And we are also asking people to watch
- 7:38Speaker 2: out for any signs and domestic pick or horses and
- 7:42Speaker 2: neurological science and if they discover anything like that then
- 7:47Speaker 2: please contact the Department of Industry, Tourism Trade straight away
- 7:51Speaker 2: so they can come out and assess the situation.
- 7:54Speaker 1: Well, Nina, we always appreciate your time. Thank you so
- 7:57Speaker 1: very much for having a chat with us this morning.
- 8:00Speaker 2: Thank you, thank you.
- 8:01Speaker 1: That is Nina Kurtz there, who is the director of
- 8:04Speaker 1: the of Medical Entomology, the Medical Entomology Unit with nt Health.
