Third Wave Alert in India (2022):
India seems to be clearly in its third wave of Covid-19. According to genome sequencing reports, Omicron has been responsible for most positive infections across Delhi NCR, Mumbai and Kolkata. However, even though Omicron is considered more infectious than the Delta variant, their severity (higher hospitalisation rates, ICUs and deaths) is likely to be lower.
Cause of Third Wave:
There are several reasons:
- Genetic Mutations: The Omicron variant has about 30 mutations in its S-Proteins compared to the Delta variant, which has only about 9. The higher the S-Protein mutations, the higher can be its transmissibility rate. i.e., a single person can infect up to six other people. (considering the recent events in South Africa).
- Social Gatherings: The risk of spreading the infection in crowded places or places with insufficient ventilation is higher. Outbreaks have often been reported in places where people gather in large numbers, often in crowded indoor settings such as restaurants, bars, festivals, and places of worship.
- Not following COVID-19 protocols: It includes not wearing masks and not maintaining good hygiene.
COVID Second Wave and its Cause in India:
The second wave in India had come as a surprise for most people and the new variants, especially with the number of COVID-19 cases spiralling down towards the end of 2020. As a result, people let their guard down, which allowed the virus to spread, even more, causing the second wave of COVID-19.
