The cases of flu caused by the virus H3N2 is spreading across the country, according to recent reports from ICMR. ICMR data show that in the past three months, 10% of SARI (Severe acute respiratory infection) patients hospitalized with H3N2 complications needed oxygen and 7% required ICU care.
People most at risk for H3N2 and other strains of flu are children below 5 years of age, ageing adults, pregnant women, and those with chronic conditions such as diabetes, asthma, kidney disease and heart disease. This viral strain causes prolonged illness and has led to more hospitalizations than flu infections caused by other type of strains. People whose immunity is weak are more likely to suffer from complications such as pneumonia, bronchitis, and seizures, where H3N2 can also be life-threatening in some cases. Various Health Authorities recommend seasonal flu vaccination for high-risk groups such as healthcare workers, pregnant women, people suffering from chronic diseases, older adults above 65 years of age and children between 6 months to 5 years of age.
Dr. Manabendra Nayak, Consultant, Downtown Hospital says, “This year, the H3N2 sub-type of the flu virus has led to a more severe flu illness. 4-in-1 flu vaccination can protect against all 4 strains of flu virus including H3N2.” Dr. Hirumoni Saikia, Consultant, Agile Hospital, says, “Flu infections can cause serious illness in children below the age of 5 years. This year H3N2, the sub-type is the cause of most flu infections and may be severe leading to hospitalisation. Vaccination is one of the effective ways to prevent Flu. It may not only protect against H3N2 but also 3 other subtypes of the flu viruses.”
