How to tell the difference between H3n2 Influenza and Covid-19?

H3N2 Influenza: A significant source of worry is India's dramatic increase in cold and flu illnesses. Scientists from the Indian Council of Medical Research (ICMR) have linked these cases of fever and a prolonged cough to influenza A subtype H3N2.

Types of Influenza

Seasonal influenza can often be divided into kinds A, B, C, and D. According to the World Health Organization, seasonal epidemics of sickness are brought on by the spread of influenza A and B viruses (WHO).

Difference between H3N2 influenza and COVID-19 Symptoms

The viruses that cause COVID-19 and H3N2 influenza are both highly contagious. They have the capacity to significantly modify as well as disseminate via droplets. Although each of these respiratory infections are very contagious, they are caused by different virus families. H3N2 is a subtype of the influenza A virus that is currently circulating in humans, whereas COVID-19 is brought on by the SARs-CoV-2 virus. According to reports, compared to other strains, the latter can result in more hospitalisations.

Major Symptoms of Influenza

Up until now, upper respiratory tract symptoms have been reported in the majority of flu cases. This covers symptoms including a dry cough, headache, fever, sore throat, and runny nose, among others. A persistent cough that just won't go away has been noticed, though. The Indian Medical Association (IMA) estimates that a seasonal fever will last five to seven days, but that the cough may linger for as long as three weeks in certain people.

How to know if it is COVID or Influenza?

The only guaranteed method to determine if you have the flu or COVID is to get tested for it. You can choose between an RT PCR test, which is more accurate but takes longer to produce results, and a rapid antigen test, which delivers data more quickly. A respiratory sample, such as a nasal swab, is required for flu and COVID tests in order to detect the flu virus.
