Omicron less severe than Delta for children younger than 5 years

The finding led by researchers at the Case Western Reserve University in the US show that the Omicron variant is 6-8 times more infectious than the Delta variant.

Children younger than five years who are infected with Omicron have less risk of severe health outcomes than those infected with the Delta variant of coronavirus, according to a study.

The research, published in the journal JAMA Pediatrics, is the first large-scale study to compare the...read more

The Karnataka government has identified 31 lakh beneficiaries in the 15 to 18 age group for the first dose of vaccination and 12 lakh elderly people above the age of 60 years The Karnataka government has identified 31 lakh beneficiaries in the 15 to 18 age group for the first dose of vaccination and 12 lakh elderly people above the age of 60 years with comorbidities across the state for a booster dose. Sources in the health department stated that till date, the state government has vaccinated 76 per cent of the targeted population against Covid.

The initiative will be taken with missionary zeal in the wake of fears of the Omicron variant and the third wave of Covid. The health department officials maintained that the number of elders might be more and they will also be covered when the

SARS-CoV-2 can damage heart blood vessels without infecting them

Image
The SARS-CoV-2 virus may contribute to the damage of small blood vessels in the heart as seen in severely-ill Covid-19 patients, without infecting them, a study shows. The research, published in the journal Clinical Science, indicates blocking antibodies could represent a new treatment to alleviate cardiovascular complications. A multidisciplinary research team led by the University of Bristol, UK, analysed how SARS-CoV-2 interacts with heart cells causing the myocardial damage seen in COVID-19 patients. Until now, it remained unclear whether heart cells are infected by the virus or damaged because of an excess cytotoxic defence response.   This response, also known as the cytokine storm', comes from our immune cells, whereby cytotoxic cells attack and kill the infected cells by releasing proteins, called cytokines. The study also investigated whether heart cells contribute to producing excess cytokines. The team led by Professor Paolo Madeddu exposed human heart pericytes, which a
