Delta Covid Variant

Rats collected in the study tested positive for alpha, delta and omicron variants of the SARS-CoV-2 virus.

The administration of Covaxin as a booster dose enhances vaccine effectiveness against COVID-19's Delta variant and gives protection against Omicron variants BA.1.1 and BA.2, a study by ICMR and Bharat Biotech has found.

Out of 279 swab samples tested during the 12th genome sequencing series in Mumbai, 278 were found infected with Omicron sub-variants of coronavirus and 1 with the Delta strain, the Brihanmumbai Municipal Corporation (BMC) said on Monday.

The Omicron subvariants may burn themselves out in the next couple of months and there could be another outbreak of Delta or a different coronavirus strain this summer, according to a modelling study conducted in Israel.

A heat-stable COVID-19 vaccine that is being developed in India and does not need cold chain storage has generated strong antibody response against coronavirus variants, including Delta and Omicron, according to a study on mice.

Official sources say that the growth revenue collections has also boosted country's tax-GDP ratio for 2021-22 to 11.7 per cent

During America's last surge of the coronavirus driven by the Delta variant, people who were unvaccinated but survived Covid were better protected than those who were vaccinated and not previously infected, a new study said Wednesday.

Kerala Health Minister Veena George has cautioned people against the rapid spread of COVID-19 in the state during the third wave and said both Delta and Omicron variants of the virus are contributing to the ongoing unprecedented surge in daily cases.

Indian Council of Medical Research's (ICMR) Head of Epidemiology and Communicable Diseases Dr Samiran Panda on Tuesday said that the Omicron variant of coronavirus is gradually replacing the Delta variant in many states across the country.

Maharashtra Health Minister Rajesh Tope on Friday said there are no clear guidelines from the Centre on the treatment of patients detected with the Omicron and Delta variants, especially on the usage of Molnupiravir, an oral, direct-acting antiviral.

A United Nations report said on Thursday that the deadly wave of COVID-19 Delta variant stole 240,000 lives in India between April and June in 2021 and disrupted economic recovery, and warned that "similar episodes" could take place in the near term.

A preliminary US study of nearly 70,000 Covid positive people showed a substantially reduced risk of hospitalisation and death from Omicron even after controlling for growing population immunity levels.

Singapore can expect an infection wave due to Omicron "several times larger" than the one caused by Delta, Health Minister Ong Ye Kung said in Parliament on Monday as he cited the latest variant's higher transmissibility.

A Cypriot scientist defended his assertion that a new strain of Covid-19 exists that combines characteristics of the delta and omicron variants.

Nearly 80-85% of Covid cases reported in Tamil Nadu were people who had 'S' gene drop in their samples, indicating contraction of Omicron variant while remaining 15-20% was Delta variant, Tamil Nadu Health Minister Ma Subramanian said on Sunday.
