India’s Covid-19 cases have been significantly concentrated in Maharashtra, Gujarat, Rajasthan, Delhi and Tamil Nadu. These states account for roughly 70% of India’s confirmed cases. Moreover, data from the Health Ministry’s National Centre for Disease Control (NCDC) revealed a consistent pattern, where these states also accounted for most cases of Swine Flu (H1N1) since 2015. The NCDC has recorded this year’s Swine Flu cases as part of India’s Integrated Disease Surveillance Programme.
Key Points: Historical Data of Swine Flu
In 2019, Rajasthan, Gujarat, Delhi, and Maharashtra were responsible for around 54% of Swine Flu cases in India. Meanwhile, Tamil Nadu, Maharashtra, Rajasthan, and Gujarat contributed 65% of the cases in 2018. Despite being among India’s most populous states, Uttar Pradesh and Bihar do not consistently make it to the top list, despite intense migration activities to other states for work-related reasons.
The Comparison between Covid-19 and Swine Flu
Both diseases trace their origins back to pathogens from non-human hosts, yet they belong to different virus families. They are both respiratory viruses that spread through contact. Both diseases infiltrate the lungs and cause characteristic pulmonary infections, albeit with varying lethality.
Swine Flu infections often have a higher case fatality rate and can cause significant deaths in children and adults under 60. On the other hand, Covid-19 tends to be more fatal to those above 60, with children largely spared. However, due to the insufficiency of research, scientists aren’t able to definitively identify which age groups are safer or at higher risk.
High Prevalence of Covid-19 and Swine Flu in Gujarat and Maharashtra
Gujarat and Maharashtra have consistently reported high numbers of both Covid-19 and Swine Flu cases. The prevalence of these diseases may be due in part to migration for work.
Influenza Patterns and Observations
Typically, India experiences peak influenza activity (viral infections of the upper or lower respiratory tract) during February and March. Most cases in northern India occur during the summer months whereas, in southern and western India, majority of the cases are reported during the winter months.
Scientists suggest that another wave of Covid-19 infections cannot be ruled out due to the virus’s novel nature. As for Swine Flu, 2020 saw an unprecedented increase in testing and active surveillance across states-a contrast to the past when only a few states had the infrastructure and system to actively report cases.
Both Maharashtra and Tamil Nadu boast 50 testing laboratories each for Covid-19, many of which also serve for Swine Flu testing.
Swine Flu Overview
Swine Flu, caused by the H1N1 virus, is a respiratory tract infection. Its symptoms include cough, nasal secretions, fever, loss of appetite, fatigue, and headache. Historically, it was known to occur in people who had been around pigs, hence its name. This virus primarily spreads through airborne transmission over short-distances, particularly in crowded enclosed spaces. Hand contamination and direct contact are also potential transmission routes.
