Influenza A virus subtype H3N2: H3N2 influenza, a subtype of the virus that causes flu and causes more hospitalisations than other variants, is thought to be responsible for the surge in cases of persistent cough, fever, and Covid-like symptoms that have been reported in recent days across the nation.
“This year we are seeing a lot of Flu cases. Symptoms are slightly different and more severe than what was seen in previous years. Lots of patients are complaining of persistent cough or bouts of cough which keep going on for many days sometimes even for weeks after the flu settles. Normally, we don’t see flu cases in North India in February, or March. Till now, we are seeing a lot of cases coming in. Seasonality has got extended in most of the countries,” said Dr Sandeep Budhiraja, Group Medical Director – at Max Healthcare & Senior Director – Institute of Internal Medicine.
The influenza A subtype H3N2 is causing respiratory issues for many Indians, according to the Indian Council of Medical Research (ICMR) and the Indian Medical Association (IMA).
It results in a three to five-day fever and a three to four-week-long cough. Patients are exhibiting all H3N2 symptoms, including fever, coughing, fatigue, headaches, muscular aches, sore throats, and nasal congestion.
The IMA has advised physicians to avoid giving patients antibiotics before determining whether the ailment is bacterial because this can lead to resistance. Antibiotics are not necessary for the majority of present cases of fever, cough, sore throat, and body aches, which are caused by influenza.
