In Hong Kong, Hepatitis E Strain Jumps From Rats to Humans

World's first human case of rat disease discovered in Hong Kong

World's First Human Case Of Rat Disease Found

Dr. Siddharth Sridhar, clinical assistant professor at the University of Hong Kong said, "Previous laboratory experiments have found that rat hepatitis E virus can not be transmitted to monkeys, and human hepatitis A virus can not be transmitted to rats", explaining that when it comes to disease susceptibility, monkeys are the closest to humans.

The man contracted the disease after he underwent a liver transplant following chronic infection with hepatitis B. With no obvious case, the patient continued to exhibit symptoms of abnormal liver function. Scientists estimate that it could take food, pasukim infected droppings. It wasn't until they tested frozen samples of a rat from 2012 that had once roamed the area that they found a potential source: the dead rat had the virus, according to the Post. This is thanks to "lots of commonalities between rats and humans", he said.

The world's first human case of rat disease has been diagnosed in China.

The man is said to be recovering. More than 60% of emerging infectious diseases originate in animals. There are many infections that go "undiagnosed or misdiagnosed" he added.

When they tested rodent samples that health officials had collected in his neighborhood in recent years, they found Hepatitis E in at least one rat.

A man in Hong Kong has been found to have a strain of hepatitis E that had only been seen previously in rats, researchers said Friday.


There is no treatment for hepatitis but it usually clears up by itself. But Adalja said he thinks that the man's suppressed immune system is more likely the explanation for this case.

"We don't know if in future there will be a serious outbreak of the rat hepatitis E virus in Hong Kong", said Kwok-yung.

"This example of it actually occurring means that we probably should start looking more for it, especially in immunocompromised people".

Past year researchers from Oxford University first demonstrated that hepatitis B virus is associated with an increased risk of Parkinson's disease.

Symptoms of the human strain of hepatitis E include jaundice and sometimes tiredness, fever, nausea, vomiting and abdominal pain.

Until now, it has been widely accepted that hepatitis E can not be transferred from rats to humans. Most cases resolve on their own, according to the CDC.
