A study conducted by researchers from Boston University, Icahn School of Medicine at Mount Sinai, and New York University has revealed that SARS-CoV-2 infection can lead to lasting damage to the dorsal root ganglia, resulting in symptoms of Post-COVID Conditions or Long COVID. The study found that thousands of genes associated with neurodegeneration and pain-related pathways were affected even after the viral infection had been cleared. The researchers observed a progressive increase in sensory sensitivity over time in an…

Two recent publications appear to have bolstered the case for a natural origin connected to a “wet market" in Wuhan. These markets sell live animals, often housed in poor conditions, and are known to be sites where new pathogens jump from animal to human. Early cases of covid-19 clustered around this market. But critics counter that there are so many missing data about the epidemic’s initial days that this portrait may be inaccurate. The opposing idea of a leak from a laboratory is not…

In the most comprehensive autopsy tissue study conducted to date, researchers have found traces of the SARS-CoV-2 virus throughout the entire body, from the brain and the heart to the eyes. The findings indicate the virus can cause persistent infections in many parts of the body, months past an initial illness, and support the argument for further research into antiviral drugs as possible treatment for long COVID.Three years have passed since the emergence of novel coronavirus SARS-CoV-2, and scientists are still working…

A new scientific study suggests that the benefit of the original COVID booster shot is reduced for people who had already had a COVID-19 infection. The study also showed that the mRNA COVID-19 vaccines were less protective against Omicron than earlier COVID variants.Primary mRNA <span class="glossaryLink" aria-describedby="tt" data-cmtooltip="<div class=glossaryItemTitle>COVID-19</div><div class=glossaryItemBody>First identified in 2019 in Wuhan, China, COVID-19, or…

Last week, Indian pediatrician Soumya Swaminathan announced on Twitter that she is leaving her post as chief scientist at the World Health Organization (WHO) at the end of this month. She plans to return to India to work on public health there. Swaminathan, 63, joined WHO in 2017 and in March 2019 was named the agency’s first chief scientist, a position created by Director-General Tedros Adhanom Ghebreyesus to make sure “WHO anticipates and stays on top of the…

According to a new research study, all individual COVID-19 infections include multiple variants of the SARS-CoV-2 virus.More detailed tracking of virus genetic variations can provide early warning to public health efforts.Researchers at Case Western Reserve University (CWRU) genetically sequenced the viral infections in 360 COVID patients.

Even as the nightmare involving deadly new variants of COVID-19 had started making people gloomy, the arrival of vaccines changed the grim narrative and infused a lot of optimism. But the need for treatments for those at high risk of severe illness after being infected with COVID-19 and people with a weak immune system who may not generate a robust response to the vaccines was always felt. In the last few months, there has been significant progress in developing effective antibody-based therapies. At present, three such…
