Why might face masks reduce COVID-19 severity?

Face masks reduce the spread of the new coronavirus and may also lessen the severity of COVID-19. The present study finds that masks increase the humidity of the air that a person breathes. The researchers propose reasons that explain why increased humidity may reduce the severity of COVID-19 cases. Researchers have found that wearing a

One-third of patients may experience ‘long COVID’

A study has found that 32% of people who tested positive for SARS-CoV-2 were still experiencing at least one symptom 6 weeks after their tests. The most common of these symptoms were fatigue, shortness of breath, and a loss of taste or smell. People with relatively mild COVID-19 usually recover within 2–3 weeks of the

COVID-19: Quicker recovery may indicate long-term immunity

Researchers recently found that some people who recovered quickly from COVID-19 continued to have antibodies against SARS-CoV-2 for several months. This discovery suggests the potential for long-term protection among those with a strong initial immune response. According to the Centers for Disease Control and Prevention (CDC), there have been more than 9 million confirmed COVID-19

COVID-19 can disrupt electrical activity in frontal lobes of brain

A review of research suggests that abnormalities in the front of the brain identified by electroencephalography (EEG) tests are common among patients who have neurological symptoms with COVID-19. Estimates vary, but approximately 15–25% of patients with severe COVID-19 may experience neurological symptoms, such as headaches, confusion, delirium, impaired consciousness, seizures, and strokes. Doctors may refer

COVID-19 vaccine successfully protects macaques against virus

A new study has found that a COVID-19 vaccine candidate is highly effective in protecting rhesus macaque monkeys from the disease. Developing a safe and effective vaccine is central to stopping the spread of SARS-CoV-2, the virus responsible for COVID-19. While emergency measures that authorities put in place to promote physical distancing and protect those

Convalescent plasma appears safe for treating COVID-19

Transfusions of plasma from people who have recovered from COVID-19, the illness that SARS-CoV-2 causes, appear to be safe for severely ill patients and may speed their recovery, according to a preliminary study. For more than 100 years, doctors have used convalescent plasma (a component of blood) from people who survived life threatening infections to

5 false claims about coronavirus remedies and why they are wrong

Have you ever heard that taking vitamin D supplements or following a ketogenic (keto) diet will protect you from the new coronavirus? In this Special Feature, we explain why these and other persistent myths are not grounded in science. Even before the World Health Organization (WHO) declared the new coronavirus outbreak a “pandemic,” their director

Novel coronavirus: What we know so far

The current outbreak of infections with a novel type of coronavirus has sparked global anxiety and concern that the virus might spread too far and too fast and cause dramatic harm before health officials find a way to stop it. But what are the realities of the new coronavirus outbreak? We investigate. In December last
