India’s second wave of pandemic

Date: 10 May 2021 Tags: Reports & Indices

Issue

India’s daily number of cases has been surging over 4 lakh. This has been attributed to the deadly second wave that has hit our health systems hard.

 

Background

India’s daily cases began showing a decline from September 2020. However, the new wave is faster and more severe.

 

Details

  • The major reason for ferocious increase is the lack of Covid appropriate behaviour that includes discarding masks and avoiding physical distancing.

  • There is also blame on election rallies for the surging cases but majority of cases have emerged in states with no elections such as Maharashtra, Delhi and Karnataka.

 

Biological factor

  • Scientists have assumed that biological changes in the virus may have a role to play in increasing number of cases.

  • Viruses mutate regularly so as to avoid anti-bodies. In recent months, several mutants of the virus have been found that further strengthens the theory.

  • Some strains of the virus are assumed to have greater potential to transmit. The B.1.617 variant found in Vidarbha has the ability to transmit at a faster rate and avoid immune response.

 

Other factors

  • The surge in numbers cannot be attributed to a single factor such as mutated versions. Other climatic and demographic reasons could also hold true.

  • Large gathering of people such as weddings, festivals, markets etc could also be the reason for prolonged exposure to virus and increasing cases.

 

Threatening variants

  • The B.1.617 is already under watch by the government. Other sub-variants such as B.1.617.1, B.1.617.2 and B.1.617.3 also have the same transmission capability.

  • The South African and UK variant have also been considered a concern but the Brazilian variant should not be a threat.
