Which bats carry Hendra virus?

Hendra virus is a virus that infects large fruit bats (flying foxes). Occasionally the virus can spread from flying foxes to horses and horses can then pass the infection on to humans. A small number of people who had very close contact with infected horses have developed Hendra virus infection.

Where is Hendra virus most common?

Since 1994, Hendra virus (HeV) has been the cause of death in over 100 horses. Most cases have been the result of spillover infection from flying-foxes. Others have been the result of direct transmission from infected horses. To date, all cases have occurred in Queensland (Qld) and New South Wales (NSW).

Who is a natural host of Hendra virus?

Hendra virus (HeV) infection is a rare emerging zoonosis (disease that can be transmitted to humans from animals) that causes severe and often fatal disease in both infected horses and humans. The natural host of the virus has been identified as being fruit bats of the Pteropodidae Family, Pteropus genus.

How common is Hendra virus in horses?

Hendra is a rare disease, however the death rate related to infection is very high – more than 70 per cent in horses. A small number of people have been infected with the virus, via close contact infected horses. Tragically 4 of the 7 people who were infected have died.

Do flying foxes carry lyssavirus?

Flying foxes in Australia are known to carry two infections which can pose a serious risk to human health – Australian bat lyssavirus and Hendra virus. Human infections with these viruses are very rare and when there is no handling or direct contact with flying foxes, there is negligible public health risk.

What diseases do bats carry in USA?

The two most common diseases associated with bats in the United States are rabies and histoplasmosis.

Can humans survive Hendra virus?

Hendra virus is a rare disease that can be passed from an infected horse to a human. This type of illness is called a zoonotic disease. The cases reported in Australia have all been in people who had close contact with infected horses. Without prompt medical treatment, the complications of Hendra virus can be fatal.

How long does Hendra virus last in the environment?

After 4 days, the highest survival was 29% in July (the month with the highest overall survival) for Kempsey (the location furthest south). Pattern of Hendra virus survival over a 4-day period after excretion showing the mean for 1993–2012 simulated for a each season at Rockhampton and b all locations in July.

Can dogs get Hendra virus from bats?

There are two viral diseases affecting bats that can also infect dogs. These are Hendra virus and Lyssavirus. There have been no cases in Australia, where dogs have been clinically ill from either of these viruses.

Can horses survive Hendra virus?

Approximately 80% of horses and 70% of people infected with Hendra virus die. Properties with confirmed infected animals are jointly managed by Biosecurity Queensland, and the animal owner and their veterinarian until it can be determined there is no further transmission risk.

How fatal is Hendra virus?

Without prompt medical treatment, the complications of Hendra virus can be fatal. There is no cure, human vaccine or specific medical treatment for Hendra virus. A vaccine for horses has been available since 2012. The best defence is avoiding contact with an infected horse.

Do all bats have lyssavirus?

Surveys of wild bat populations have indicated less than one percent of bats carry ABLV. In sick and injured bats, around 7% have been found to carry the virus. ABLV is one of twelve types of lyssavirus which are found around the world. ABLV is the only one of these known to occur in Australia.

Do little brown bats carry diseases?

Little brown bats sometimes carry diseases, but they are otherwise unable to cause much harm to humans. Many people fear bats because they carry rabies. But even though this species can transmit rabies to humans, it’s also exceptionally rare. Do little brown bats attack humans?

Do all bat species carry rabies?

All bats do not carry rabies. Less than 1/2 of 1% of all bats may contract the disease. A variety of wild animals (rabies vector species) can catch rabies, including foxes, skunks, raccoons, coyotes and bats.

Can horses survive Hendra?

The clinical signs of Hendra virus in horses are mainly respiratory and/or neurological usually with a rapid progression to death and with a 79% mortality rate. Some horses diagnosed with Hendra have recovered from the disease, and to date, they have all been euthanased.

Is lyssavirus fatal?

Rabies virus and Australian bat lyssavirus (ABLV) belong to a group of viruses called lyssaviruses. These viruses are usually transmitted via a bite from an infected (“rabid”) animal. They all cause a similar illness known as rabies, which affects the central nervous system and is usually fatal.

Can lyssavirus be cured?

Both are spread by bites and scratches. These diseases can be prevented by rapid and thorough cleaning of the wound and by vaccination. There is no cure.

What percentage of bats in the US have rabies?

Most bats do not have rabies. For example, even among bats submitted for rabies testing in the U.S. (these only included bats capable of being captured), only about 6 percent had rabies. There is no way to determine if a bat has rabies by simply looking at it.
