Scientists study whether immune response wards off or worsens Covid

Research into antibodies could explain children ’s protection against disease, or why virus causes life-threatening effectsCoronavirus – latest updatesSee all our coronavirus coverageBritish scientists have launched a major study aimed at uncovering the critical role that human antibodies and other immune defences play in the severity of Covid-19 cases.Results could support some scientists ’ belief thatantibodies triggered by common colds could be protecting children against the disease. Alternatively, the study could confirm other researchers ’ fears that some immune responses to the virus may trigger deadly inflammatory reactions that could bedevil attempts to create anti-Covid vaccines.Continue reading...

The COVID-19 pandemic has had a worldwide effect for what seems like an eternity. After shelter-in-place orders became more prevalent in March,  most people probably didn’t think they’d still be wearing masks in October. So the question remains, when will the pandemic end?  It turns out there are quite a few factors that contribute to the rise and fall of a pandemic, some within our control, some that are not. An outbreak becomes a pandemic when it meets two criteria, first, it spreads rapidly and widely, and second, it must qualify as a severe disease. If either of these factors change, it is no long...

I live-tweeted a fascinating and perhaps rather depressing meeting with William Haseltine via a Reuters Newsmaker Broadcast. His talk was upbeat but the message does not offer a positive outlook unless we can collaborate internationally to identify, trace, and isolate and go back to early antivirals to treat people urgently. A vaccine will probably never be found, we must stay on top of this virus when we get communities under control. Moreover, we must recognise that another emergent pathogen could appear any time. These are essentially my notes from Haseltines’s talk. Might we ever achieve herd immunity? There is n...

Conclusion In 1919 George A. Soper1 wrote that the deadly Spanish Flu pandemic that swept around the earth was without any precedents, and that there had been no such catastrophe ‘so sudden, so devastating and so universal’. He remarked that, “The most astonishing thing about the pandemic was the complete mystery which surrounded it. Nobody seemed to know what the disease was, where it came from or how to stop it. Anxious minds are inquiring today whether another wave of it will come again”. With close to 3 million positive cases and around 0.2 million deaths worldwide, the coronavirus has compelle...

Abstract The emerging coronavirus SARS-CoV-2 has caused a COVID-19 pandemic. SARS-CoV-2 causes a generally mild, but sometimes severe and even life-threatening infection, known as COVID-19. Currently, there exist no effective vaccines or drugs and, as such, global public authorities have so far relied upon non pharmaceutical interventions (NPIs). Since COVID-19 symptoms are aspecific and may resemble a common cold, if it should come back with a seasonal pattern and coincide with the influenza season, this would be particularly challenging, overwhelming and straining the healthcare systems, particularly in resource...

If you’re reading this from home due to the COVID-19 pandemic, then you’re likely not the only one. Even at The Medical Futurist, we are working from home to bring you the latest digital health news in a timely manner. One of the latest trends of interest to governments is the immunity passport, or some certified methods to ensure someone has antibodies against SARS-CoV-2 in order to move around. We have already discussed scenarios about how and when the pandemic will end, but we’ve also analyzed the ways that life will drastically change. One of the major changes we could experience is the introductio...

Abstract Coronaviruses are a large group of viruses known to cause illnesses that vary between the common cold and more severe diseases to include severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS). A novel coronavirus was identified in December 2019 in Wuhan city, Hubei province, China. This virus represents a new strain that has not been previously identified in humans. The virus is now known as the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and the resulting disease is called coronavirus disease 2019 (COVID-19). The World Health Organization (WHO) declared the...

In early April, about four months after a new, highly infectious coronavirus was first identified in China, an international group of scientists reported encouraging results from a study of an experimental drug for treating the viral disease known as COVID-19. It was a small study, reported in the New England Journal of Medicine, but showed that remdesivir, an unapproved drug that was originally developed to fight Ebola, helped 68% of patients with severe breathing problems due to COVID-19 to improve; 60% of those who relied on a ventilator to breathe and took the drug were able to wean themselves off the machines after 18...

One of the worst symptoms of any plague is uncertainty—who it will strike, when it will end, why it began. Merely understanding a pandemic does not stop it, but an informed public can help curb its impact and slow its spread. It can also provide a certain ease of mind in a decidedly uneasy time. Here are some of the most frequently asked questions about the COVID-19 pandemic from TIME’s readers, along with the best and most current answers science can provide. A note about our sourcing: While there are many, many studies underway investigating COVID-19 and SARS-CoV-19, the novel coronavirus that causes the illn...

Naveen Ramesh, Archana Siddaiah, Bobby JosephIndian Journal of Occupational and Environmental Medicine 2020 24(1):16-18 Coronaviruses are zoonotic viruses and six species of Coronaviruses are known to cause human disease such as cause common cold, severe acute respiratory syndrome and the Middle East Respiratory Syndrome. In January 2020, scientists in Wuhan, China isolated a novel coronavirus (SARS-CoV-2), responsible for an outbreak of unknown pneumonia that had not been previously reported among humans. This virus spreads from person to person, through respiratory droplets, close contact, and by touching surfaces or ob...
