VietNamNet Bridge – Of 25 mice tested by the Ho Chi Minh City
Pasteur Institute, three are positive for virus Hata that causes acute renal
failure. All of them are sewer-rats.
The Ho Chi Minh City Pasteur
Institute’s representative said the institute made the test after a patient who
was bitten by a rat had continuous high fever and signs of kidney failure.
Scientists randomly caught 25
rats, including sewer-rats and house-rats in the area around the patient’s
home, for testing in order to find pathogens that can harm human. Three rats
were detected to carry the Hanta virus.
On October 17, a 55-year-old man
from Ward 9, District 3, Ho Chi Minh City, was brought to the Hospital for
Tropical Diseases in a state of prolonged high fever. The next day the patient
patients showed signs of kidney failure. Tests showed that he carried the Hanta
virus from mice. The patient said that he had previously been bitten to the leg
by a rat during sleep.
Dr Tran Phu Manh Sieu, director
of the HCMC Preventive Health Center, said Hanta virus transmits through the
mouse bites or the contact with mouse urine. The HCM City Hospital for Tropical
Diseases occasionally received patients infected with this virus and all of
them were exposed to rats.
According to the doctors, the
disease may go away after 7-10 days. However, it is dangerous that there is no
preventive vaccine for this disease. Fortunately, not everyone is bitten by
rats and not any sewer-rat carries this virus.
