  • Flushing public toilets propels Covid virus 5 feet up in air
    NEW DELHI, APRIL 21 (IANS): Respiratory droplets are the most prominent source of transmission for Covid-19. However, flushing a toilet can generate large quantities of microbe-containing aerosols depending on the design, water pressure or flushing power of the toilet at public restrooms, an Indian-origin researchers-led study has warned. Public restrooms are especially cause for concern for transmitting Covid-19 because they are relatively confined, experience heavy foot traffic an
  • Covid-19: What is gut's response to immunity
    London, April 20 (IANS) Our guts may not provide long-lasting systemic immunity from Covid-19, which is where immune cells circulate through the body to provide protection to other organs, finds a new study that may have implications for oral coronavirus vaccines. A team of researchers from the University Hospital Erlangen, Germany, studied the role of the gut in providing systemic immunity to this virus. An analysis of blood samples from patients infected with SARS-CoV-2 reveale
  • Covid vax 'safe' in people with high-risk allergies: Study
    New York, April 20 (IANS) Severe allergic reactions to Covid-19 vaccines remain exceedingly rare, thus people with high-risk allergy histories can safely take the jabs, according to a study of 65,000 people. Individuals with severe allergies to foods, oral drugs, latex, bee stings or venom can safely receive the Covid-19 vaccines, stated the experts led by allergists at Massachusetts General Hospital (MGH) in the US.

  • This asthma drug can speed up recovery in Covid patients
    London, April 19 (IANS): Inhaled budesonide -- primarily an asthma drug -- can shorten recovery time among Covid patients aged over 50, according to a study. Early treatment with inhaled budesonide cut recovery time by a median of three days in Covid-19 patients at higher risk of more severe illness, said researchers from the University of Oxford. The findings, from the preliminary trial, showed 32 per cent of those taking budesonide recovered within the first 14 days of treatmen
  • 'Is microbial life, including viruses, changing too?'
    New Delhi, April 19 (IANS) With alarms sounded about the declining diversity of plants and animals, a related concern with equally profound implications is posed: Is the variety of microbial life, including viruses, changing too -- and if so, in which direction and how fast? In a paper published on Monday, David S. Thaler of the University of Basel, Switzerland, and Guest Investigator at The Rockefeller University's Programme for the Human Environment (PHE), notes "clearly
  • Symptoms post Covid recovery may impact daily life: Doctors
    New Delhi, April 18 (IANS) Are you a Covid-19 survivor, but still feel fatigued and not having fully recovered? You may be experiencing what is known as "Long Covid". The symptoms may not be life-threatening, but can persist for months and impact daily life, experts say. While most patients who were affected with SARS-CoV -- the virus behind the deadly coronavirus -- and recovered, may do fine, but some are likely to face symptoms, including fatigue, shortness of breath, &
  • This is how highly infectious Covid variant gets neutralised
    New York, April 18 (IANS) Scientists have revealed how a highly infectious variant of SARS-CoV-2 virus binds to host but succumbs to antibodies later, a discovery that could help in the development of more potent Covid vaccines. Large-scale supercomputer simulations at the atomic level showed that the dominant "G form" variant of the Covid-19 causing virus is more infectious partly because of its greater ability to readily bind to its target host receptor in the body, comp
  • Wearing 2 masks doubles protection against Covid virus
    New York, April 17 (IANS) Scientists now report that wearing two face coverings can nearly double the effectiveness of filtering out SARS-CoV-2-sized particles, preventing them from reaching the wearer's nose and mouth and causing Covid-19. The reason for the enhanced filtration isn't so much adding layers of cloth but eliminating any gaps or poor-fitting areas of a mask, according to the study published in JAMA Internal Medicine. "The medical procedure masks are des

  • Global Covid numbers up as cases rise in India, Turkey and Brazil: Greed and Fear report
    New Delhi, April 17 (IANS) Covid cases are now rising again on a global basis which was not the case as recently as late February and this pick up is mainly due to India, Turkey and Brazil, according to Christopher Wood of Jefferies. In his Greed and Fear financial commentary, Wood noted that the 7-day average daily Covid case count globally bottomed at 358,583 on 20 February and has since risen by 378,035 or 105% to 736,618, or only 0.4% below the peak reached in mid-January.

  • Ancient wisdom will help build immunity to beat Covid
    New Delhi, April 16 (IANS): Going beyond precautions and vaccinations, doctors and the World Health Organization (WHO) have advised that proper nutrition and hydration would be key in fighting the second wave of Covid-19. This is a throwback on some essential ancient wisdom. 2500 years ago, Hippocrates, the Father of Medicine, hit the nail right on the head when he said: "Let food be thy medicine and medicine be thy food." In January, the CSIR-Centre for Cellular and Molec
  • Covid survivors may only need one vaccine dose: Study
    Washington, April 16 (IANS) People who have recovered from Covid-19 require only one vaccine dose. A second jab is important for those who have not had Covid-19 to reach strong immunity, suggests a study. The study, led by researchers from the University of Pennsylvania in the US, found that Covid survivors had a robust antibody response after the first mRNA vaccine dose, but little immune benefit was seen after the second dose. On the other hand, those who did not have Covid-19
  • Why wearing mask is not enough to keep Covid at bay
    New Delhi, April 16 (IANS) With Covid-19 spreading fiercely in many parts of the country, it has now become extremely important to follow all the precautionary measures, besides wearing a mask, to keep infections at bay, health experts have said. It is important to understand that the virus responsible for Covid-19 spreads mainly from person to person. Therefore, coming in close contact with a sick person can put them in danger. Doctors have therefore advised that in times like t
  • Young Covid survivors not safe from reinfection: Lancet
    New York, April 16 (IANS) If you are planning to avoid vaccination just because you are a Covid survivor, think twice. According to a new study, despite a prior Covid-19 infection young people can likely catch the virus again and may still transmit it to others. Even after a previous infection and the presence of antibodies, vaccination is still necessary to boost immune responses, prevent reinfection, reduce transmission, and that young people should take up the vaccine wherever po
  • 3rd vax dose likely needed within 12 months: Pfizer CEO
    Washington, April 16 (IANS): Pfizer Chief Executive Officer Albert Bourla said people will likely need a third dose of the Pfizer/BioNTech Covid-19 vaccine within 12 months of getting fully inoculated. Bourla told CNBC News on Thursday that it is possible people will need to get vaccinated against the coronavirus annually, reports Xinhua news agency.

  • Rare blood clotting risk more for COVID-19 than for vaccines: Oxford study
    New Delhi, April 15 (PTI) The risk of rare blood clotting known as cerebral venous thrombosis (CVT) following COVID-19 infection is several times higher than post-vaccination, according to a study unveiled on Thursday. The study led by researchers at the University of Oxford in the UK counted the number of CVT cases diagnosed in the two weeks following diagnosis of COVID-19, or after the first dose of a vaccine.   They compared these to calculated incidences of CVT fo
  • Covid: Air pollution can worsen outcomes in asthma patients
    New York, April 15 (IANS) Exposure to higher levels of air pollution is likely to increase the severity of Covid-19 among people suffering from respiratory conditions such as asthma or chronic obstructive pulmonary disease (COPD), warns a study. Researchers from the University of Cincinnati in the US found that a one-unit increase in particulate matter 2.5 was associated with a 60 per cent higher chance of hospitalisation for Covid-19 patients with pre-existing respiratory disease.
  • Daily exercise in youth can give you a robust life after 40
    New York, April 15 (IANS) Maintaining a daily exercise routine in youth may help reduce risk of high blood pressure or hypertension and dementia in later life, according to a study. People with moderate exercise for at least five hours a week during early adulthood had 18 per cent lower risk of developing hypertension than for those who exercised less than five hours a week. The likelihood was even lower for participants who maintained their exercise habits until age 60. While
  • Why are some Covid-19 survivors at risk of blood clot?
    SINGAPORE, APRIL 14 (IANS): People who have recovered from Covid-19, especially those with pre-existing cardiovascular conditions, may be at risk of developing blood clots due to a lingering and overactive immune response, according to a study. The study, led by researchers from the Nanyang Technological University in Singapore, found that recovered Covid-19 patients had twice the normal number of circulating endothelial cells (CECs) that had been shed from damaged blood vessel wall
