Continual surveillance of natural bats for emerging viruses is needed

Findings from a study conducted by Chinese researchers suggest that similar species of bats carry similar viruses and that when these bats reside in overlapping areas, transmission between species occurs more easily.

Stray dogs possible origin of COVID-19 pandemic

After tracing coronavirus signatures in different species, a new research article published in the journal Molecular Biology and Evolution shows that stray dogs (more specifically dog intestines) may have acted as the origin of current severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic.

California COVID-19 herd immunity theory debunked

A recent theory suggesting that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was doing the rounds in California as early as November 2019, infecting thousands undetected and leading to herd immunity, was debunked by experts from the scientific community. Antibody testing by a group of Stanford Medicine researchers was linked to the theory.

Ebola drug effective against key enzyme of coronavirus that causes COVID-19

Scientists at the University of Alberta have shown that the drug remdesivir is highly effective in stopping the replication mechanism of the coronavirus that causes COVID-19, according to new research published today in the Journal of Biological Chemistry.

Re-thinking the built environment to limit coronavirus transmission

The coronavirus disease (COVID-19) global pandemic has taken a toll on many countries across the globe. The hardest-hit countries are now grappling to contain the spread of various through social distancing measures, while others are now in total lockdown.

How does COVID-19 attack the body?

The coronavirus disease (COVID-19) attacks the lungs, leading to pneumonia, and eventually, a cascade of serious complications. But how does COVID-19 kill? Is it the virus itself or the result of the person’s immune system response?

Novel coronavirus attacks and destroys T cells, just like HIV

The immune system has many components that work together in protecting the body from foreign invaders. One of the most important types of immune cells is T lymphocytes or T cells, a type of white blood cell that acts as the core of adaptive immunity, the system that modifies the immune response to specific pathogens.

Extend lockdowns to stave off second wave of COVID-19

Social distancing, keeping people at home, and lockdowns are being implemented in many nations to prevent the spread of the highly infectious severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Some countries that have seen declines in the number of new infections due to lockdowns are now looking to allow people to return to more normal daily routines.

Cost of ‘repurposing’ existing drugs to treat COVID-19

The paper looks at repurposed drugs that might demonstrate efficacy against COVID-19, and if they could be manufactured profitably at very low costs to ensure affordable access to vital treatments for COVID-19 at low prices globally.

Monitoring loss of smell could be key to COVID-19 detection

Researchers have found that persons who test positive for COVID-19 disease have common symptoms, including fever, cough, shortness of breath, and a temporary loss of the sense of smell.

Missing COVID-19 antibodies suggest mystery immune response

Researchers at Shanghai Public Health Clinical Center have made important discoveries about the immune response among patients who have recovered from mild COVID-19 disease that could help to inform prevention and treatment methods, as well as improve the efficacy of community testing.

Remdesivir shows promise in post-infection treatment for COVID-19 disease

The coronavirus disease (COVID-19) has no approved treatment or vaccine as the world grapple with its wrath. The viral infection has so far infected 1.8 million and killed more than 114,000 people. Now, a team of scientists has shown that an experimental antiviral drug, remdesivir, has shown promise in treating patients with severe COVID-19.

Physical-distancing slows spread of COVID-19 and reduces ICU admissions

The world is now at a standstill, as many countries have imposed restrictions to stem the spread of the coronavirus disease (COVID-19). Nations are in lockdowns indefinitely, until the situation improves. The vast spread of the novel coronavirus is now inevitable, as the number of confirmed cases topped 1.85 million, many scientists are determining health measures that could help mitigate the global pandemic.

Cats, ferrets more vulnerable to COVID-19 than dogs

A recent Chinese study published on the preprint server BioRxiv finds that cats and ferrets appear to be extremely vulnerable to the virus, but dogs, pigs, and poultry do not seem to contract it. As preprints, papers are not yet peer-reviewed, undergoing only basic scientific screening.

Recovered South Korean COVID-19 patients test positive again

Following the reports from different countries of patients recovered from coronavirus disease (COVID-19) but testing positive again during the control diagnostic appraisal, South Korea's Centers for Disease Control and Prevention (CDC) documents a similar occurrence in 51 patients.

Novel ventilator bed hoods keep coronavirus contained within ICU

Researchers from the University of Melbourne have come up with devices called ventilation hoods that could help decrease the spread of COVID-19 from ICU patients to health workers who treat them, and to other patients.

Testing One, Two, Three - Over 75% of people with COVID-19 are asymptomatic

A new study published in the British Medical Journal in April 2020 suggests that the number of people infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is astonishingly higher than the number of cases reported so far. This could help shape future social distancing measures.

Hypertensive patients on ACE inhibitors and angiotensin receptor blockers may have improved COVID-19 prognosis

Emerging concerns that common antihypertensive treatment approaches with angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs) – jointly known as renin-angiotensin-aldosterone system (RAAS) inhibitors – may exert a negative effect in COVID-19 patients are not grounded in scientific evidence, as reported by researchers in a recent review article published in Mayo Clinic Proceedings journal.
