We Are Mutating Coronavirus, but It Is Evolving Back

Study reveals mutations of SARS-CoV-2, the virus that causes COVID-19, may not be a random process, but instead, humans are mutating it as part of a defense mechanism to degrade the virus. The findings may help in the creation of a vaccine for coronavirus. Read More

COVID-19: Using wastewater to track the pandemic

Examining wastewater is helping researchers track coronavirus infection trends. The waste reflects the viral load excreted by a population within a few hours and can help establish COVID-19 community hot spots. While researchers will not be able to calculate the exact number of community cases of coronavirus by examining wastewater, they can trace the increase of SARS-CoV-2 concentration and track the level of infection rate.

Hopes of COVID-19 pandemic respite this spring may depend upon what happens indoors

In addition to physical distancing and improved personal hygiene practices, the seasonal moderation of relative humidity indoors could help slow rates of transmission for COVID-19. However, the virus can still be transmitted via contact and close proximity to those infected, regardless of the season, researchers warn. Read More

Samples from those who had COVID-19 could illuminate true infection rate, lethality, and vaccines

VirScan, a new antibody detection tool, can analyze blood samples collected from people who have recovered from COVID-19 to learn about how the virus affects the immune system and the epidemiology of the infection. Read More

COVID-19 pandemic likely to go in waves

A new mathematical model shows the current COVID-19 pandemic could decline during the summer months, but return in the fall, with a major resurgence next winter. The model takes into account the seasonal variations of other closely related respiratory coronaviruses. Based on other coronavirus data, the model reveals infections were ten times more common between December and April in the northern hemisphere than between July and September. Researchers emphasize this model only attempts to examine possible scenarios, as we are currently unsure how warmer temperatures will affect SARS-CoV-2. Read More

Tuberculosis BCG-based vaccine may be effective against COVID-19

VPM1002, a vaccine candidate based on the tuberculosis BCG vaccine, may be effective in protecting against COVID-19. Previous studies in mice have shown the BCG vaccine is effective at protecting against several respiratory viral infections. If effective against coronavirus, researchers hope the vaccine can bridge the time gap until a specific SARS-CoV-2 vaccine is available. Read More

Research team has isolated the COVID-19 virus

A team of Canadian researchers has isolated SARS-CoV-2, the viral agent responsible for COVID-19. Isolating the virus will help researchers worldwide to develop better diagnostic tests, treatments, and vaccines for the pandemic virus. It will also help researchers to better understand the virus biology, evolution, and viral shedding. Read More
