H3N2 cases in Delhi: Doctor's tips on how to prevent viral fever, cough, covid-like signs

What starts as a chill and a fever can quickly turn into something far more unpleasant. In many patients, symptoms drag on — persistent coughs, sore throats, nasal congestion, body aches and extreme fatigue are common. “While most people recover within 5 to 7 days, we are seeing cases where coughing lingers for weeks, sometimes leading to complications,” says the expert.

In rare cases, nausea and vomiting may also occur. Those severely affected might struggle to breathe, a red flag that medical intervention is urgently needed. At-risk groups — children, elderly citizens, pregnant women and individuals with underlying health conditions — are particularly vulnerable. “It’s crucial they don’t delay seeking professional help,” Dr Minz adds.

Small habits can stop a big spread

Despite the alarming rise in numbers, experts believe the situation can be brought under control with responsible public behaviour. That starts with simple preventive measures: mask up in public spaces, wash your hands often, avoid touching your face unnecessarily and practise cough hygiene — like covering your mouth and nose with a tissue or your elbow.

“You’d be surprised how effective warm water, proper hydration and nutritious meals can be in strengthening your immune system. It’s old-school advice, but it still holds true,” he says.

If the symptoms continue for more than a week, don’t dismiss it as a minor bug. “Early diagnosis could prevent the virus from taking a more serious turn. With such a high rate of household infection in Delhi-NCR, it's time for community awareness, vigilance, and timely medical care. This flu season, caution and care could make all the difference,” the expert says.
