Japanese encephalitis detected in Eastern Australia


Japanese encephalitis virus (JEV) has been detected in piggeries in New South Wales, Queensland and Victoria.

Date published:
1 March 2022
Media type:
Media release
Audience:
General public

Japanese encephalitis virus (JEV) has been detected in piggeries in New South Wales, Queensland and Victoria.

Australian Chief Veterinary Officer Dr Mark Schipp said JEV had been confirmed by laboratory diagnosis at one piggery in Victoria’s north, six piggeries in NSW, and in one piggery in Queensland.

“JEV is a mosquito-borne viral disease that mostly occurs in pigs and horses, but can cause disease in people and rarely other animals,” Dr Schipp said.

“Animals and people become infected through the bite of infected mosquitoes. It cannot be caught through eating pork or pig products. The disease is not transmitted from person to person.

“This is the first time the virus has been detected in southern Australia, and biosecurity authorities are working with their human health departments to understand the implications and risks of human exposure.

“The Department of Health and the Department of Agriculture, Water and the Environment are collaborating closely, together with state and territory counterparts.

“We are meeting regularly and working together to work through the next steps of this situation.

“We’re asking anyone who works with pigs or horses, even if they’re a pet in the backyard, to keep an eye out for and report any possible signs of this disease.

“The most common symptoms in pigs are mummified or stillborn piglets, or piglets who show neurological problems in the first six months of life. The disease tends to be asymptomatic in adult sows, but boars can experience infertility and testicle congestion.

“Horses can experience a range of symptoms. While most infected horses do not show signs of disease, some more severe signs of JEV in horses include fever, jaundice, lethargy, anorexia and neurological signs which can vary in severity.

“JEV is a nationally notifiable disease, which means if you suspect an animal is showing signs of the disease, you must report it (see contact details below). Measures should also be taken to protect animals from mosquitoes – for instance, applying a safe insect repellent and putting a summer rug on horses.”

Acting Chief Medical Officer Dr Sonya Bennett said JEV infections can be contracted by humans through the bite of a mosquito. There are no confirmed human cases in Australia at this stage, although this is under active investigation. “We are aware that several cases of encephalitis of unknown cause have been identified in New South Wales, Victoria and South Australia within the past month.

“JE is also a notifiable disease in humans and health authorities across the country are on the alert for human cases and are in direct contact with people associated with the affected piggeries” Dr Bennett said.

“Pigs are the focus from a human health perspective as they can infect mosquitoes who then infect humans. This is not the case with horses.

“Severe illness arising from JEV infection in humans is rare and most people will have no symptoms at all if infected.

“However, a very small proportion of people infected may develop a serious illness such as encephalitis and experience symptoms including neck stiffness, severe headache and coma, and more rarely, permanent neurological complications or death.

“Encephalitis is the most serious clinical consequence of JEV infection. Illness usually begins with symptoms such as sudden onset of fever, headache and vomiting.

“Anyone experiencing these symptoms, particularly if they’ve visited regions in eastern Australia or South Australia where there has been high mosquito activity, should seek urgent medical attention.

“Clinicians should be aware of the possibility of infection caused by JEV in patients in affected areas with encephalitis and refer people for appropriate testing, after other common causes have been excluded.

“There is work underway to plan for targeted vaccinations. Two different vaccines are available for protection against JEV in Australia and are very safe and effective for both adults and children.

“However, prevention is always better than a cure and there are simple steps we can all take to avoid our exposure to infected mosquitos.

“People in areas of high mosquito activity in Eastern Australia should use mosquito repellent containing picaridin or DEET on all exposed skin.

“Wear long, loose fitting clothing when outside, and ensure accommodation, including tents, are properly fitted with mosquito nettings or screens.

“We will continue to meet with health authorities in the states and territories to progress the public health response to this disease.”

To report suspected JEV in pigs or other animals, contact your local veterinarian or call the national Emergency Animal Disease Watch Hotline on 1800 675 888.

Several more patients in NSW were undergoing testing and more cases were expected to be confirmed in the state over coming weeks.

On Thursday night, Queensland Health confirmed a person infected with JEV was being treated in a Brisbane hospital after travelling to the state's south.

Victorian authorities have confirmed eight suspected cases of JEV in the state, connected to a piggery near Echuca in the state's north.

Two children aged under 10 and six adults are among the infected people, six of whom have been taken to hospital. One is also a NSW resident.

Overall, there are 16 human encephalitis cases "of unknown cause" under investigation across NSW, Victoria and South Australia, a federal Department of Health spokeswoman told AAP...
 
Japanese encephalitis virus situation declared a Communicable Disease Incident of National Significance


Australia’s Acting Chief Medical Officer, Dr Sonya Bennett, has declared the unfolding situation in Australia concerning the Japanese encephalitis virus (JEV) a Communicable Disease Incident of National Significance.

Date published:
4 March 2022
Media type:
Media release
Audience:
General public

Australia’s Acting Chief Medical Officer, Dr Sonya Bennett, has declared the unfolding situation in Australia concerning the Japanese encephalitis virus (JEV) a Communicable Disease Incident of National Significance.

The declaration was made under the Emergency Response Plan for Communicable Disease Incidents of National Significance, in consultation with the Australian Health Protection Principal Committee.

Dr Bennett’s declaration followed her giving the National Security Committee of Cabinet a briefing earlier this week on the unfolding situation regarding JEV.

“I have declared the JEV situation a Communicable Disease Incident of National Significance after determining a national approach is required in relation to coordination of health policy, interventions and public messaging,” Dr Bennett said.

“A national working group of communicable disease, vaccine and arbovirus experts has been established to support the response, including mosquito surveillance and control measures and identification of those at direct risk, and for the rollout of vaccines. Public health communications regarding mosquito protection will target affected communities."

“The Australian Government’s health and agriculture departments are working very closely with their state government counterparts to ensure a swift and coordinated response.”

On Thursday evening, Queensland officials confirmed a human case of JEV in that state. The case had recently travelled in regional parts of the state’s south and is being treated in a Brisbane hospital.

The Department of Health is aware of other cases, in multiple states, of encephalitis of unknown origin that are being investigated for arboviral diseases, including JEV.

The Australian Government will work closely with states and territories to educate the community about JEV, what precautions people should take, and symptoms to be aware of.

The Government will also work closely with the states and territories to support the distribution of vaccine doses to at-risk population groups.

JEV is a mosquito-borne viral disease that mostly occurs in pigs and horses, but can cause disease in people and rarely other animals. Pigs are the focus from a human health perspective as they can infect mosquitoes that can then infect humans. This is not the case with horses.

Humans can become infected with JEV through the bite of an infected mosquito. The virus cannot be transmitted between humans, and it cannot be caught through eating pork or pig products.

Less than 1 per cent of people infected may develop a serious illness such as encephalitis and experience symptoms including neck stiffness, severe headache and coma, and more rarely, permanent neurological complications or death.

The vast majority of infected people will show mild or no symptoms at all.

Australia’s Chief Veterinary Officer, Dr Mark Schipp, said JEV had been confirmed at 14 piggeries across NSW, SA, Queensland and Victoria.

“The key signs to look out for in pigs are stillborn or weak piglets, some with an impaired nervous system. Piglets can develop encephalitis or wasting, depression or hindlimb paralysis. Adult sows do not typically show signs of disease,” Dr Schipp said.

“In horses, many cases show no signs of the disease. Some animals may show signs of elevated temperature, jaundice, lethargy or anorexia. Other signs may include lack of coordination, difficulty swallowing, impaired vision or over-excitement."

“Pig producers are asked to be highly vigilant for signs of this disease and report unexplained pig abortions or stillbirths."

“People working with pigs, even if they’re only a backyard pet or a small herd, should take steps to control mosquitoes, as well as continuing to practice good biosecurity."

“Horse owners can also put measures in place to help their horses avoid mosquito bites, including using hooded rugs, fly masks, and applying a safe insect repellent."

“If you suspect an animal is showing signs of the disease, you must report it via your local veterinarian or the national Emergency Animal Disease Watch Hotline on 1800 675 888.”

Rise in suspected Japanese encephalitis cases

03/03/22


People living, working or visiting towns along the Murray River are being reminded to protect themselves from mosquitoes following a rise in suspected Japanese encephalitis virus (JEV) cases.

Since last week, there have been eight suspected human cases of JEV infection in Victoria, including six people who have been hospitalised.

This includes two children under 10 years old and six adults aged between 35 to 75 years old. All cases are awaiting confirmation at this time and several remain in hospital. One is a resident of New South Wales.

Deputy Chief Health Officer, Associate Professor Deborah Friedman said the eight people all had exposure to mosquitos before they became unwell.

“It’s really important for people to protect themselves from mosquito bites, especially anyone who lives, works or plans to visit areas in northern Victoria where mosquitoes are prevalent, especially if they are camping.

“There are some really simple steps people can take, including covering up exposed skin, wearing loose fitting clothing, using repellent and sleeping under mosquito nets if you’re outdoors.”

JEV is a mosquito-borne virus that can cause encephalitis in approximately one per cent of cases who become infected.

Most people who contract JEV will have no or very mild symptoms and fully recover but anyone who develops a sudden onset of fever, headache, vomiting as well as seizures or disorientation should see urgent medical attention.

Children aged under five years old and older people who are infected with JEV are at a higher risk of developing more severe illness, such as encephalitis.

Evidence of JEV has been discovered in pigs in northern parts of Victoria, as well as New South Wales and Southern Queensland within the past month, with human cases now emerging.

People should take steps to limit their exposure to mosquitoes and protect themselves by:
  • wearing long, loose fitting clothes outdoors
  • using effective mosquito repellents containing picaridin or DEET on all exposed skin
  • trying to limit outdoor activity if lots of mosquitoes are about
  • using ‘knockdown’ fly sprays and plug-in repellent devices indoors
  • sleeping under mosquito nets treated with insecticides if you don’t have flywire screens on windows on your home or are sleeping in an untreated tent or out in the open
  • using mosquito coils, which can be effective in small outdoor areas where you gather to sit or eat.

Japanese encephalitis detected in South Australian piggery

Friday 4 March 2022

The mosquito-borne disease Japanese encephalitis (JE) virus has been detected in a commercial South Australian piggery. The disease has also been confirmed in piggeries in Victoria, New South Wales and Queensland.


There are no food safety issues associated with eating pork meat or pork products due to this disease. Shoppers are encouraged to support local farmers by continuing to buy Australian pork.

The Department of Primary Industries and Regions (PIRSA) has established an incident management team, and is working closely with industry on this response. Staff on the ground are conducting surveillance activities and providing information and advice to farmers.

Chief Veterinary Officer Dr Mary Carr said that the mosquito-borne disease causes reproductive failure in pigs, primarily through stillbirths and piglets showing neurological signs including paddling, tremors or convulsions.

“The normal lifecycle of JE is between waterbirds and mosquitos, which may then accidentally spill over to pigs and horses. Mosquitoes become infected with the virus after feeding off an infected animal, and once infected, mosquitoes can spread the virus over long distances,” said Dr Carr.

“There is no treatment available for livestock which have JE, and I emphasise that mosquito management and prevention of mosquito bites is key to preventing the spread of this disease.

“People can also become infected through mosquito bites. PIRSA and SA Health are working closely together, with local industry, and with our interstate counterparts to understand the implications, and to communicate to farmers how they can reduce the risk of human exposure.”

PIRSA is also encouraging horse owners to protect their horses as they are susceptible to Japanese encephalitis if bitten by infected mosquitoes. Symptoms in horses include lethargy, nervous signs or sometimes hyperexcitability. There have been no confirmed cases of Japanese encephalitis in horses in Australia.

“We encourage horse owners to eliminate mosquito breeding grounds near their horses, such as stagnant water, to reduce the chances of them being bitten,” Dr Carr said.

“Horse owners can also stable their animals at night, use a light cotton rug and fly mask and apply a safe insect repellent.”

Japanese encephalitis is a notifiable disease and any suspect cases must be reported. PIRSA urges animal owners to report any cases of unexplained pig deaths, especially piglets, or unexplained horse illnesses, to the Emergency Animal Disease Watch Hotline on 1800 675 888.

Victoria records first Japanese encephalitis death
Cassandra Morgan
By Cassandra Morgan
Updated March 8, 2022 — 9.03pmfirst published at 6.27pm

Health authorities say a man in his 60s from northern Victoria has become the first person in the state to die from Japanese encephalitis.

The Victorian Health Department said it was investigating how the man contracted the mosquito-borne virus after an autopsy revealed it was the cause of his death on February 28.
Concerns over Japanese encephalitis

There are concerns over the spread Japanese encephalitis across several states in Australia.

As of Tuesday, there have been seven confirmed cases of Japanese encephalitis in Victoria, including the man who died.

The cases are the first ever acquired in the state as it is the first time the virus has spread below the country’s northern tip.

A federal Department of Health spokeswoman confirmed the man was the first to die in this outbreak of the virus, but his death was not the first fatal case of Japanese encephalitis in Australia.

Along with the cases in Victoria, two have been confirmed in NSW and one has been confirmed in Queensland...

Four cases of Japanese encephalitis have been confirmed in South Australia with three people acquiring their infections locally, prompting a warning for people to avoid contact with mosquitoes.

Health officials recently investigated 10 people hospitalised with acute encephalitis and said four of those were now confirmed to be the Japanese variety.

Seven of those people remain in hospital. One person has died.

Health department spokesman Chris Lease said with three of the four cases acquired locally, it was important for people to avoid being bitten by mosquitoes...

A man in his 60s has contracted Japanese encephalitis in NSW, while Victorian authorities are reporting two suspected cases.

NSW Health says the man was treated in hospital after contracting the mosquito-borne virus but has since been discharged and is recovering in a rehabilitation facility.

It is the fist confirmed case in the state's Goulburn area, with urgent investigations underway into where the exposure occurred.

Victoria's deputy chief health officer issued an update late on Friday to confirm an additional two probable cases of Japanese encephalitis there.

NSW is also testing several other people for the virus, with more cases expected to be confirmed over coming days and weeks.

The latest infections bring Australia's confirmed number of cases to 17: five in NSW, seven in Victoria, four in SA and one in Queensland.

Two of them have been fatal, one in NSW and another in Victoria...

Why is there an alert

Declaration of a Communicable Disease Incident of National Significance


On 4 March 2022, Australia’s Acting Chief Medical Officer, Dr Sonya Bennett, declared the Japanese encephalitis virus (JEV) situation a Communicable Disease Incident of National Significance. She determined a national approach was required in relation to coordination of health policy, interventions and public messaging.

The declaration was made under the Emergency Response Plan for Communicable Disease Incidents of National Significance, in consultation with the Australian Health Protection Principal Committee.

JEV is a nationally notifiable disease in both humans and animals.

What we are doing

A national working group of communicable disease, vaccine and arbovirus experts has been established.

The working group will support Australia’s response to the JEV situation. This will include:
  • mosquito surveillance and control measures
  • identification of those at direct risk, and for the rollout of vaccines.
Public health communications regarding mosquito protection will target affected communities.

The Australian Government’s health and agriculture departments are working very closely with their state government counterparts to ensure a swift and coordinated response.
