Rare Bat-Borne Virus Claims Life in Australia, Echoing Rabies-Like Symptoms
A man in his fifties has died in New south Wales, Australia, after contracting a highly unusual virus transmitted through bat contact. Health officials describe the pathogen as a lyssavirus closely related to the virus that causes rabies.
The New South Wales Health service issued a statement emphasizing the rarity of Australian bat lyssavirus (ABLV) infections. “While cases are exceptionally infrequent, there is currently no proven effective treatment available,” the statement reads. The individual, initially hospitalized in critical condition, was aware he had been infected several months prior to his death, following a bat bite.
This virus can trigger a severe and frequently enough fatal encephalitis, impacting the central nervous system. Prompt post-exposure prophylaxis, including vaccination, is crucial to prevent the disease’s progression. Though, initial symptoms can be deceptively mild, frequently enough mimicking the flu with fever, aches, and fatigue. This can delay diagnosis, allowing the condition to rapidly deteriorate, leading to paralysis and neurological confusion.
Australia has recorded only three confirmed cases of ABLV sence 1996. Globally, rabies – a similar lyssavirus – remains a notable public health concern, claiming the lives of approximately 59,000 people annually, primarily due to dog bites. Though, bat-borne lyssaviruses are emerging as a concern in various parts of the world, including Australia, Latin America, and Africa.
According to the CDC, while rabies is eliminated in many developed countries, bats are now the primary source of rabies transmission to humans in the United States. In 2023, the CDC reported 138 animals tested positive for rabies, with bats accounting for the majority of reported cases.
The delayed onset and flu-like initial symptoms of ABLV highlight the importance of seeking immediate medical attention after any bat encounter, notably if a bite or scratch occurs. Public health officials urge caution around bats and advise against handling them, even if they appear sick or injured.
