Post-H1N1 Cough Can Last Weeks: Tips for Relief
H1N1 is a virus that can cause fever, cough, sore throat and body aches.
Most symptoms improve within several days.
However, the cough can remain for a few weeks after the fever goes away.
This happens because the airways may still be irritated.
Drinking fluids and warm drinks can soothe the throat.
Steam, rest and sleeping with the head raised may also help.
Medicines should be used only when a doctor recommends them.
Antibiotics usually do not help a post-viral cough.
Older people, pregnant individuals, young children and people with other health problems should seek medical help promptly if symptoms worsen.
H1N1 cases are rising in Bengaluru, Delhi, Maharashtra and other parts of the country.
The Indian Council of Medical Research says the increase is linked to a known strain, with no new mutations making it more dangerous.
A dry or tickly post-viral cough may continue for three to four weeks after fever and other symptoms improve.
Hydration, warm fluids, steam, rest, head elevation and saline nasal sprays may help ease the cough.
Worsening cough, recurrent fever, increasing phlegm or breathlessness requires medical evaluation, especially for vulnerable groups.
