The first significant mutation of the SARS-CoV-2 coronavirus

Epidemiologists have been anxiously waiting for months for the virus responsible for the COVID-19 pandemic to mutate. Apparently it already has. In this way, a new study claims to have found the first really significant mutation of the pathogen, and for now we can breathe easy. Virus mutations occur naturally as the pathogen jumps from...

WHO does not endorse an immunity passport

The scientific evidence gathered so far does not provide certainty that a person who has contracted the coronavirus, has recovered, and has generated antibodies is protected against a second infection, leaving behind the idea of an immunity passport, according to the World Health Organization (WHO). This is WHO’s reaction to claims by some governments that...

Nose cells identified as likely COVID-19 entry points

Researchers from the Wellcome Trust Sanger Institute (United States) have identified two specific types of cells in the nose as points of probable initial infection for the COVID-19 coronavirus. In their work, published in the journal Nature Medicine, they have found that goblet and cylindrical cells in the nose have high levels of the input...

Damage from COVID-19 beyond the lungs

The disease caused by the SARS-CoV-2 coronavirus (COVID-19) continues to be surrounded by many unknowns. For now, everything points to the lungs being the main organs in which the ravages of this infection are shown. But beyond these, its reach could extend to different organs, including the heart and blood vessels, the liver, kidneys, intestine,...

Evidence of stray dogs as possible origin of COVID-19 pandemic

Since the COVID-19 was first detected, virologists work against the clock to complete the full history of SARS-CoV-2. It is a crucial detective job not only when developing a vaccine, but also to prevent future infections. That task is to examine the genetic sequence of SARS-CoV-2 and compare it to that of other known coronavirus...

Clinical manifestations of children with COVID-19

Elderly patients infected with SARS-CoV-2 are at high risk to have Severe Acute Respiratory Syndrome (SARS), complications and death. Due to unknown reasons, children with COVID-19 appear to have a milder clinical course compared to adults, and reports of death are scarce. However, pediatric population may play a major role in community spread of SARS-CoV-2....

Air pollution linked to far higher COVID-19 death rates, study finds

According to a new nationwide (US) study from Harvard T.H. Chan School of Public Health, air pollution is linked to significantly higher rates of death in people with COVID-19 ―dirty air was already known to increase the risk of Severe Acute Respiratory Syndrome (SARS), which is extremely deadly and a cause of COVID-19-related deaths, as...

Effects of temperature on COVID-19 transmission

When the SARS outbreak happened in 2002-2003, SARS-CoV spread to approximately 30 countries only. However, the current outbreak of COVID-19 by SARS-CoV-2 has spread to 176 countries or territories which suggests the enhanced ability of viruses to be aerosolized. Environmental factors such as atmospheric temperature also can modulate the survival and spread of virus aerosols...

Relationship between the ABO blood group and the COVID-19 susceptibility, study finds

A study have compared the ABO blood group distribution in 2,173 patients with COVID-19 confirmed by SARS-CoV-2 test from three hospitals in Wuhan and Shenzhen, China, with that in normal people from the corresponding regions. Recent clinical observation suggests that patient age, male sex and certain chronic medical conditions (e.g., cardiovascular disease, diabetes, COPD) seem...

Turning COVID-19 patients upside down is saving lives

Some healthcare professionals turn patients on their stomachs because it seems like an effective way to keep them stable in Intensive Care Units (UCIs). The idea is to help patients get the much-needed oxygen in their lungs by facing them. This has seen cases that have improved in a matter of a very short time,...
