Macaques show low neutralizing antibody and cellular immune response to SARS-CoV-2

A new study published on the preprint server bioRxiv* in August 2020 presents a cynomolgus macaque model that develops symptomatic SARS-CoV-2 infection in a mild form, with low or no antibody responses, making it suitable to study human responses to vaccines and drugs targeting the virus.

COVID-19 causes significant dilation of lung blood vessels, indicates study

A new pilot study from the Icahn School of Medicine at Mount Sinai suggests that COVID-19 is causing significant dilation of the blood vessels of the lung, specifically the capillaries.

Researchers compare COVID-19 transmission risk when singing, speaking and breathing

Now, a new study* set to determine if singing and playing of woodwind and brass instruments produce more respiratory droplets and aerosols than speaking. Further, they want to know if the size and temperature of the venue will make a difference in the accumulation of aerosol droplets in the air.

Study: Biological components combined with socioeconomic factors increases tooth decay

Nationally, rates of early childhood caries, or tooth decay, among Hispanic, American Indian, Native Hawaiian and Other Pacific Islander children are almost double those of white children, making it the most prevalent chronic disease among these populations--occurring five times as frequently as asthma.

No evidence of active SARS-CoV-2 in breastmilk of infected women

A recent study published in the journal JAMA in August 2020 suggests that SARS-CoV-2 RNA does not represent replication-competent virus and that breast milk may not be a source of infection for infants.

Geographers conduct first daily surveillance of emerging COVID-19 hotspots

Over the course of the coronavirus epidemic, COVID-19 outbreaks have hit communities across the United States. As clusters of infection shift over time, local officials are forced into a whack-a-mole approach to allocating resources and enacting public health policies.

Lack of consistency in COVID-19-related data could harm prevention efforts

Since COVID-19 emerged late last year, there's been an enormous amount of research produced on this novel coronavirus disease.

Influenza A virus can spread by airborne aerosolized fomites, finds study

Viruses like the influenza virus and even the novel coronavirus are capable of spreading from person to person via airborne droplets as well as dust, fibers, and other surfaces. Now, a new study provides evidence of airborne virus transport on microscopic particles called “aerosolized fomites.”

Genetically engineered mosquitoes to be released in Florida Keys

Mosquitoes are known to be vectors or bearers of several viral and protozoal infections such as dengue, Zika, yellow fever, Chikungunya, and malaria. These infections are known to infect and even kill millions around the world each year. In order to tackle this vector-borne menace, researchers have genetically engineered mosquitoes that could replace the infection carrying species of the mosquitoes.

Research finds link between COVID-19 mortality and morbid obesity

The prevalence of morbid obesity in a population is associated with negative outcomes from COVID-19, according to an analysis by researchers at The University of Alabama of morbid obesity data and reported COVID-19 deaths in the United States.

Websites selling home-based COVID-19 testing kits providing inadequate or misleading information

In the UK and US, many websites are selling direct to user self-sampling and testing kits to detect SARS-CoV-2. Recently, a cross-sectional observational study was carried out to check the completeness and accuracy of information provided by these websites.

New SARS-CoV-2 vaccine effective in macaques

Researchers from the biotechnology company Novavax in Gaithersburg, Maryland, have developed a vaccine against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that successfully induces immunogenicity and protection against the virus in macaques.

COVID-19 could compromise key element of immune response

Researchers at the University of Melbourne have made the unsettling discovery that infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) might compromise the activation of the CD8+ T-cell responses that would usually ameliorate disease and drive recovery in cases of respiratory disease.

Post-mortem study of dead COVID-19 patients finds lung damage and blood clots

A new post-mortem study of patients who have died from COVID-19 found severe damage to the lungs and signs of blood clotting in major organs.

Whey protein from human breastmilk inhibits SARS-CoV-2 infection

Many scientists have reported the effects of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection on pregnancy and the virus has been detected in breastmilk. Now a new study published on the preprint server bioRxiv* in August 2020 shows that whey protein in human breastmilk efficiently prevents infection with SARS-CoV-2 as well as post-entry viral replication.
