What is H3N2?
H3N2 is an influenza virus which spreads from pigs to humans. H3N2 is a subtype of influenza A virus after H1N1. It is highly contagious that spreads from one person to another. According to the Centers for Disease Control and Prevention, the virus was first identified in US pigs in 2010. People of all-age groups could be vulnerable to H3N2. Elderly patients with comorbidities need to be more careful.
What health experts say
According to health experts, these viruses generally spread during weather changes as viruses find conducive time to multiply and transmit among people rapidly. The infection of H3N2 virus may continue for five to seven days. People generally take a week to recover while in some patients, recovery period has been seen 10 to 12 days.
Doctors and health specialists are of the view that the rising cases of H3N2 influenza is not a cause of concern, but people are advised to stay safe. People are advised not to panic but they should follow Covid pandemic protocols. Maintaining basic health hygiene, social distancing, avoiding crowded places, wearing masks, getting sound sleep, eating balanced diets, staying hydrated, practicing Yoga and physical work-out will enable a person to keep the flu at bay.
Medically, a symptomatic treatment is recommended to ease symptoms like fever, cough and nasal congestion. Adequate rest with home-cooked fresh food and proper hydration is deemed to be the best medicine to get recovery. However, painkillers, paracetamol, cough suppressants and nebulizers are recommended by doctors to give relief to patients.
It is quite difficult to differentiate the symptoms between Covid and flu. There are some common symptoms seen in both patients of Covid and flu: sore throat, cough, headache, body ache, weakness, tiredness and fever. As per health experts, H3N2 can cause throat hoarseness, while in the case of Covid 19 a patient could have a fever or stuffy nose. In the flu, a patient could feel intense body ache and dry cough could last for a longer period. In Covid 19 patients, loss of smell and taste could be seen with rashes on the body.
WHO underlines the famous maxim: “Prevention is better than cure.” According to the World Health Organisation, vaccination is the most effective way to prevent the flu disease. Vaccines are safe and effective, which have been used for more than 60 years. Inoculation is recommended annually to protect against influenza as body immunity gained from vaccination goes down over time.
WHO says that vaccination is quite important for people at high risk of influenza complications. Influenza vaccine provides protection cover among healthy adults, even when circulating viruses are mutants. For elderly people, influenza vaccination can reduce severity of disease
