The patient is currently undergoing treatment on ventilator support at the Government Medical College, Kozhikode.Health Minister K. Muraleedharan said officials have been directed to remain vigilant, noting that the patient’s symptoms and initial test results indicate a likely Nipah infection. Authorities are preparing a detailed contact list and monitoring those who may have been exposed, including healthcare workers. The state government has assured that necessary medicines and treatment facilities are available, while urging the public to remain calm until the final test results are received. 

Kerala has heightened surveillance measures after a preliminary test indicated that a 43-year-old man from Kozhikode may have contracted the Nipah virus, officials confirmed on Thursday.

Health authorities said the patient’s samples have been forwarded to the National Institute of Virology (NIV) in Pune for definitive testing, with confirmation results expected soon. Meanwhile, the Health Department has begun identifying and monitoring individuals who may have come into contact with the man, a businessman from Feroke.

Officials stated that the patient was first admitted to a private healthcare facility before being transferred to the Government Medical College in Kozhikode on Wednesday. He is currently receiving treatment on ventilator support. Kerala has witnessed several Nipah outbreaks since 2018, with fruit bats recognised as the primary carriers of the virus.

Speaking to reporters late Wednesday, Health Minister K. Muraleedharan said health authorities in Kozhikode had been instructed to remain on alert. He noted that while final confirmation from NIV is still awaited, the patient’s symptoms and initial test findings strongly suggest a Nipah infection.

The minister said the patient had interacted with numerous individuals before being hospitalised. He had visited a hospital’s outpatient department and later underwent MRI and echocardiography procedures, prompting authorities to advise potentially exposed healthcare workers and others to remain in quarantine as a precaution.

Muraleedharan added that all necessary preparations have been made at Kozhikode Medical College to manage the situation. He urged the public not to panic, explaining that the patient had recently cleaned a rented warehouse himself, which is suspected to be the source of exposure. According to the minister, the man initially developed a fever that subsided before recurring, eventually leading to his admission to hospital.

Information available on the website of Kerala’s Directorate of Health Services describes Nipah virus as a zoonotic infection that can spread between animals and humans. Fruit bats, commonly known as flying foxes, are considered the natural hosts of the virus, which can also infect pigs and humans.

The virus can cause encephalitis, or inflammation of the brain, resulting in illnesses ranging from mild symptoms to severe disease and death. Outbreaks are reported almost every year in parts of Asia, particularly in India and Bangladesh.

The health advisory notes that infection risks can be reduced by avoiding contact with infected bats and pigs and by refraining from consuming raw date palm sap that may be contaminated. During outbreaks, strict infection-control measures in healthcare facilities are considered essential to limit person-to-person transmission.

Muraleedharan also announced that he would convene a meeting with health officials on Thursday to assess the evolving situation. Efforts are underway to map the patient’s movements and identify all contacts, with authorities noting that the contact list is extensive. He added that required medicines are available at the Medical College and that further action will depend on the final test results from NIV.
