"The IDSP-IHIP data from health facilities indicate that during the month of January 2023, a total of 397,814 cases of Acute Respiratory Illness/Influenza Like Illness (ARI/ILI) were reported from the country that increased slightly to 436,523 during February 2023. In the first 9 days of March 2023, this number stands at 133,412 cases," the Health Ministry said in a statement.
"Seasonal H3N2 flu is a human flu from H3N2 that is slightly different from one of the previous year's flu season H3N2 variants. Seasonal influenza viruses flow out of overlapping epidemics in East Asia and Southeast Asia, then trickle around the globe before dying off. Identifying the source of the viruses allows global health officials to better predict which viruses are most likely to cause the most disease over the next year," said Shuchin Bajaj, a doctor, and director at Ujala Cygnus Hospitals.
Meanwhile, the ministry has said: "Oseltamivir is the drug recommended by WHO. The drug is made available through the Public Health System free of cost. The government has allowed the sale of Oseltamivir under Schedule H1 of the Drug and Cosmetic Act in February 2017 for wider accessibility and availability."
