In the second wave of corona, more people living in a house have been hit by corona. That is, if a member of the household got corona infected, then most of the family members could not save themselves from getting infected. The reason behind this is attributed to the Corona Delta variant (B.1.617.2). This variant was first found in India in October 2020.

According to the report of the Times of India, Public Health England (PHE), the health organization of the UK government, has done a study on this. According to the study, the B.1.617.2 variant spreads more rapidly in household settings i.e. people living together in the house than B.1.1.7. The study shows that the delta variant spreads 64% faster in a household than the alpha variant first found in the UK.

Delta variant more dangerous

“Overall, we found B.1.617.2 to be more contagious than B.1.1.7 among households living together,” said the study released on Friday. Through this study, evidence has been found that the delta variant is more infectious.

Delta variant behind second wave in India

According to researchers, it was because of the delta variant that the second wave of corona in India became so dangerous. Many states of South India are currently facing this wave. Due to the different variant of Corona, only one person in a house was getting infected, while the Delta variant infected more than one person in the family.

According to the study, the delta variant is a faster decision as compared to the alpha variant (B.1.17) in the household setting. The Alpha variant was first detected in the UK. However, both the variants were declared as Variants of Concern by the World Health Organization (WHO).

1.80 lakh deaths due to delta variant in India

The second wave in India started on 11 February and turned catastrophic in April. In a study, a variant of Corona has been found in the country, Delta Super Infectious, which spread very rapidly during the second wave. It has killed more than 1.80 lakh people in India. It is not known for sure whether the antibody or vaccine is effective against this variant.

WHO says that the effectiveness of the vaccine on the delta variant, can not say anything on how effective the drugs are. It is also not known how much risk of reinfection is due to this. Preliminary results say that the effectiveness of a monoclonal antibody used in the treatment of Covid-19 has decreased.
