Health authorities said that the condition of none of the patients was critical.

In Kerala, facilities to conduct the tests to confirm the disease are currently available only at the unit of the National Institute of Virology in Alappuzha. However, as the Institute is overburdened with samples, the results for H3N2 tests are being delayed. In view of the situation, the authorities have initiated procedures to conduct tests for H3N2 at the Public Health Laboratory in Thiruvananthapuram also.

Meanwhile, the Directorate of Health Services (DHS) advised elderly people, young children, expectant women and people suffering from serious ailments to exercise caution regarding H3N2. They should seek treatment as soon as symptoms of the disease, which is a variety of influenza (flu), are observed, said DHS authorities.

Persistent cough, sometimes accompanied by fever, being reported across the country for the past two to three months is due to Influenza A subtype H3N2, Indian Council of Medical Research (ICMR) experts said recently.
