The current scenario in India:
Currently, many people are having a high fever and cough that lasts for more than 2 weeks. Hospitals and clinics are filled with outpatients having fever as the main concern. According to doctors and experts, this is due to the sudden change in the season and the spread of the H3N2 virus, a subtype of influenza A virus. The mornings (early) and nights are cooler, while the days are sunny. This change in temperature has caused most people to fall sick.
Also, the early spring has been the reason for the worsening of symptoms in vulnerable individuals having respiratory conditions like sinusitis, asthma, allergies, etc.
