Never be afraid to raise your voice for honesty and truth and compassion against injustice and lying and greed. William Faulkner

2) Viruses are not living things. They are tiny particles that can only make copies of themselves inside the cells of living things, like humans. When a virus makes copies of itself, it doesn't always make perfect copies.
2) This study looks at the risks of COVID-19 for people traveling to space. 
2) The Wuhan strain of SARS-CoV-2 caused serious damage to the lungs of infected mice. The mice had a very high chance of dying from this strain. The researchers also looked at the bacteria in the lungs and guts of the infected mice. 
2) A brief reminder :
2) Researchers at WEHI announced that they discovered a new drug that can stop long COVID symptoms in mice. This drug is more effective than the current top treatment, Paxlovid, for both long COVID and acute COVID cases. 
2) Long COVID is a complex condition that affects many people after they have had COVID-19. It can cause a wide range of symptoms that last for a long time. There are not many clear guidelines on how to diagnose and treat Long COVID. 
2) On one hand, they need to spread like wildfire from person to person. But on the other hand, they also have to make tons of copies of themselves inside each infected host.
2) Let me try to explain in simple words.
2) Imagine that SARS-COV-2 succeed to hide inside certain immune cells called macrophages in the lungs, and then spreads from one macrophage to another, allowing it to persist for a very long time.
2) Our body is able to fight off viruses that's making you sick.
2) ...drawing from a wealth of published research due to the intricacy of the topic. 
2) Over 3 years, researchers sampled 1,462 bats in Cambodia Steung Treng province, identifying extensive and diverse coronaviruses co-circulation. Using metatranscriptomic and amplicon sequencing, they generated 33 complete sarbecovirus genomes. 
2) The finding in this study of persistently higher anti-N antibody levels in people with Post-Covid Condition (PCC) compared to those with acute infection only, does seem paradoxical at first glance. 
2) T-cells are like the superheroes of our immune system - they work hard to protect us from germs and viruses.
2) The most important immune components in the nasal tissue for fighting COVID-19 are:
2) With a really fast-spreading virus going around, like the one that causes COVID-19, when someone gets sick, they can pass the virus to other people. But some sick people end up spreading it to a lot more people than others. 
2) ... sensory, and autonomic dysfunction in patients. Researchers propose a "Broken Bridge Syndrome" where COVID-19 disrupts the vital connection between the brainstem and cerebellum, contributing to the diverse neurological symptoms of Long COVID. 
2) These T cell responses are important for fighting off the virus, even as it mutates. 
2) Herpes viruses, like the one that causes cold sores, were 3 times more common in cancer patients with COVID-19 compared to others. Nearly 30% of cancer patients with COVID-19 had the herpes virus reactivate, while it didn't reactivate at all in non-cancer patients with COVID 
2) SARS-CoV-2 leverages major cities as hubs to spread across regions. New variants are often first introduced into populous urban areas, which then act as central points for rapid dissemination to surrounding suburbs and other regional cities. 
2) The researchers found that the children with severe liver inflammation had very high levels of a type of immune cell called CD8 T-cells in their livers.
