In certain situations, the dog provided a swift sniff to signal the presence of Covid-19 in a person, while in other cases, the dog was presented with a sweat sample for detection, which could take a few minutes.

The study found that at least 20 per cent of Covid-infected people do not develop symptoms or they remain asymptomatic.

Before SARS-CoV-2, the virus that causes COVID-19, spread across the world in 2020, tuberculosis was responsible for more deaths globally than any other infectious disease.

No study had identified a "smoking gun" - a mechanism that might explain this apparent risk imbalance.

There are still unanswered issues about the reasons underpinning why some COVID patients continue to have reduced exercise ability while others recover without this issue.

Pennsylvania State University researchers in the US partnered with Evaxion Biotech on a study that was the first to demonstrate the effectiveness of an AI-generated vaccine in a live viral challenge model.

The rise of Covid and influenza cases in India may lead to fatal as people will be co-infected by the viruses and if not treated on time, said health experts

At 18 months, the effects were more modest in males, with maternal SARS-CoV-2 positivity linked to a 42 per cent higher odds of a neurodevelopmental diagnosis at this age.

The team showed that with the aid of these mutations, several such Omicron recombinant and mutant strains were able to escape from the host's defences and bind more tightly to the host cell.

Health Minister urged people with co-morbid conditions like hypertension, sugar, heart ailments and cancer to be very careful and take precautions from SARS-CoV-2.

The findings, published in the journal Current Biology, indicates that efforts to promote healthy sleep duration ahead of an immunisation could be an easy way to improve vaccine effectiveness.

The team led by researchers at AIIMS Patna noted that COVID-19 can lead to multiorgan damage through the angiotensin-converting enzyme-2 receptor (ACE2), abundant in testicular tissue.

An international team of researchers has identified a pan-variant and ultra-potent neutralising antibody that can offset Omicron variants.

New York: Rather than evolving from regular transmission among millions of humans, the coronavirus variants of concern from chronic, long Covid patients can be more deadly and need urgent attention, scientists have warned. Earlier studies have shown that some immune-compromised people, such as those taking medication for other chronic disorders, have carried active Covid infections […]

Hyderabad: In general, an antibody test (serological test) for Covid-19 is performed in specialized labs, and to get results it takes anywhere from 24 hours to several days. But a new paper test developed by researchers from the Massachusetts Institute of Technology (MIT) has shown that it takes only 10 minutes to find the level of neutralizing antibodies […]

Hyderabad: For a long time we have been told about the overall health benefits of having a cup or two of black tea. It now turns out that the black tea not only has impact on holistic health but also can limit the ability of SARS-CoV-2 virus to replicate. A ground breaking collaborative study by […]

New Delhi: A cancer patient in US’ Connecticut has become the second longest-known in the world to be infected with Covid as he suffered the infection 471 days, according to a pre-print study, not peer-reviewed. An immunocompromised person in the UK is known to have been the world’s longest-known Covid sufferer — at 505 days. […]

California: Researchers have measured the stability and infectivity of four variants of SARS-CoV-2 in 5-10 um-wide aerosolized droplets over a period of 5 seconds to 20 minutes and found a reduction in infectivity by around 90% after 20 minutes; loss of infectivity was associated with relative humidity and aerosol pH, providing insight into the mechanisms […]

Washington: A commercial COVID test can quickly determine if you are infected with SARS-CoV-2. However, if a positive result is obtained, there is no equivalent home test to assess how long you have been protected from reinfection. In the Journal of the American Chemical Society (ACS), researchers are now reporting simple and accurate glucose meter-based […]

Bangkok: A 32-year-old previously healthy female veterinarian contracted Covid after being exposed to an infected cat, according to the first documented case of suspected cat-to-human transmission. Researchers from the Prince of Songkla University in Thailand reported the case of the vet who was diagnosed with Covid after being sneezed on by a cat owned by […]
