  • India Thursday reported 2,628 Covid cases and 18 deaths. The cumulative number of cases is 4,31,44,820 (15,414 active cases) and 5,24,525 deaths
  • Global: Over 527 million cases and over 6.28 million deaths.
  • Vaccination in India: Over 1.9 billion doses. Worldwide: Over 11.4 billion doses.
THE CATCH OF THE DAY
Risk of blood clots in lungs doubles in Covid survivors
Risk of blood clots in lungs doubles in Covid survivors
  • Covid survivors are twice as likely to develop dangerous blood clots that travel to their lungs compared to people who escape the virus, according to a large new study from the States Centers for Disease Control and Prevention (CDC). -United.
  • The chances of developing respiratory conditions like a chronic cough or shortness of breath also double in survivors.
  • Sample size: The study was based on more than 3.5 lakh of Covid patient records associated with 1.6 million people in a control group, who had seen a doctor within the same time frame but had not been diagnosed with Covid.
  • The team assessed records of the occurrence of 26 clinical conditions previously associated with long Covid. Participants were followed for 30 to 365 days after infection until any health problems emerged or until the end of the year, whichever came first.
  • The results: The study found that up to one in five Covid-19 survivors aged 18 to 64 and one in four survivors aged over 65 have experienced at least one incident condition that could be attributable to previous infection with Covid.
  • Of all the clinical conditions studied, the risk of developing an acute pulmonary embolism – a clot in an artery of the lung – increased the most, by a factor of two in adults. This can cause serious problems, including lung damage, low oxygen levels, and death.
  • In patients under 65, post-Covid risks increased for most types of conditions, but no significant differences were seen for cerebrovascular disease, mental health disorders or substance-related disorders .
  • “The occurrence of incident conditions after infection could also affect a patient’s ability to contribute to the workforce and could have economic consequences for survivors and their dependents,” the researchers say, not to mention additional pressure on health systems.
TELL ME ONE THING
Vaccination does not really protect against the long Covid
Vaccination does not really protect against the long Covid
  • Vaccination against SARS-CoV-2 offers less protection against long Covid than expected. Getting bitten reduces the risk of developing the condition by just about 15%, a new study reveals.
  • What is that: Long Covid or post-acute sequelae, which are the persistence of health conditions for months beyond the initial phase of an infection, have proven difficult to study. One of the main reasons is that the range of symptoms involved makes the disease difficult to define. Researchers are also struggling to determine the true burden of this syndrome. Some studies claim 1 in 3 survivors have long Covid, others claim the figure is 7% or less.
  • The study: With a sample of over 13 million people, this is the largest cohort ever used to look into the subject.
  • The results: Researchers at the VA Saint Louis Health Care System in St Louis, Missouri, compared symptoms such as brain fog and fatigue in vaccinated and unvaccinated people up to six months after testing positive for Covid. The team found no difference in the type or severity of symptoms between those who had been vaccinated and those who had not.
  • The study, published in the journal Nature Medicine, further reveals that long Covid also manifests in vaccinated people who experience breakthrough infection (BTI).
  • “Our analyzes of BTI versus SARS-CoV-2 infection without prior vaccination show that, comparatively, the magnitude of the risks of death and post-acute sequelae was lower in people with BTI compared to patients not stung,” reads the study.
  • Take-out: Reliance on Covid vaccines as the sole mitigation strategy may not optimally reduce the long-term health consequences of the pandemic. The limited protection provided by vaccines means that withdrawing measures such as mask mandates and social distancing restrictions could put more people at risk, especially those with weakened immune systems.
