Kochi: Concerns related to the spread of Nipah in Kerala were allayed further, with Kerala Health Minister K K Shailaja on Friday saying a sample of one more person suspected to be infected with the potentially deadly virus has tested negative.
One more person currently being treated at the isolation ward of the Medical College Hospital in Kochi has tested negative, the minister told reporters in New Delhi.
The government had on Thursday announced that samples of six people, including three nursing staff, who had initially attended on a college student infected with Nipah virus, had tested negative.
The health of the college student, diagnosed with Nipah virus, has improved, the government said here Thursday evening. He is being treated at a private hospital here.
"He is taking food. He spoke to his family members through intercom. Fever has subsided," a government bulletin said here.
Shailaja, who is in Delhi to meet Union Health Minister Harsh Vardhan, said the state will continue to remain alert till July 15. "There is no need for any concern. Result of the sample of the seventh person is also negative," she said.
They are currently being treated at the isolation ward of the Government Medical College Hospital, Kalamassery, here. The minister said she will seek more funds from the central government to set up a virology institute at least of Level 3 standard in Kerala.
The government has also urged people to continue to take precautionary measures to prevent the spread of the disease. A total of 316 people, who were in touch with the infected person, have been kept under observation.
State Health Principal Secretary Rajan N Khobragade said out of the 316 people, 33 have been put in the high-risk category.
The Union Health Ministry has deployed a six-member team comprising an epidemiologist to conduct contact tracing for early detection of suspects and review of isolation facilities.
A designated control room has been established at the district collector's office and an isolation ward established at the Government Medical College in Ernakulam, the Health Ministry had said in a statement Tuesday. Isolation facilities have also been ensured at medical colleges at Kozhikode, Thrissur and Kottayam.
According to the World Health Organisation (WHO), Nipah virus is a newly emerging disease that can be transmitted from its reservoir (natural wildlife host), flying foxes (fruit bats), to both animals and humans.
Symptoms range from asymptomatic infection, acute respiratory infection and encephalitis. Infected people initially develop influenza-like symptoms of fever, headache, vomiting and sore throat.
This can be followed by dizziness, drowsiness, altered consciousness, and neurological signs that indicate acute encephalitis.
