Researchers from Hong Kong University has registered its first case of human infection pasukim kind of hepatitis E (HEV).
Just because this is the first case of a rat hepatitis E infection documented in a human, Adalja said, "it doesn't mean it's the first time its ever occurred in history".
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.

The human strain of hepatitis E is typically spread through contaminated water or food, according to the Centers for Disease Control and Prevention. There was no prior evidence the rodent strain could be transmitted to humans. "The patient is cured, as of this stage we can no longer detect the virus in any clinical specimen", said Sridhar.
"We postulate that contamination of food by infected rat droppings in the food supply is possible", they said in a report, as the BBC noted. "Doctors later found that he had a strain of hepatitis that was "highly divergent" from other strains found in humans".
The virus causes hepatitis, an inflammation of the liver, and can not be cured but usually heals on its own.
The man lives in public housing in eastern Kowloon after, and officials said he went through liver transplant surgery in May and was tested for recurring liver problems.
There is no treatment for hepatitis but it usually clears up by itself.
The man is now recovering after being treated in hospital, the Morning Post added.
The infected person will face a variety of symptoms like fever, nausea, discoloration of the eyes, dark urine, pale stools, and an enlarged liver.
A sustained period of hot and humid weather has caused rodent problems in Hong Kong to escalate, multiple sources reported. In most cases, the virus is spread through contaminated water.
Hepatitis E is a major health threat in developing countries in Africa and Asia and in the past has been contracted from eating undercooked pork and deer meat.
Every year, the hepatitis E virus infects about 20 million people worldwide, leading to an estimated 3.3 million symptomatic cases, says the WHO.
