New study shows COVID-19 causes severe blood vessel damage

New research published in the New England Journal of Medicine shows that the respiratory virus SARS-CoV-2, which causes COVID-19, causes severe damage to blood vessels, leading to widespread thrombosis, a press release by the Angiogenesis Foundation reports. The study was conducted by an international team of medical scientists who compared the lungs of patients who...

Runners should be further than 1.5 meters apart

The evidence so far indicates that the virus is spread from person to person through small respiratory droplets. When a person sneezes, coughs or even exhales, he or she is emitting small droplets ―often too small to see with the naked eye―, that can carry the virus. The receiving persons can be infected by inhaling...

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,...

Air pollution may be key contributor to COVID-19 deaths

High air pollution could be one of the most important factors in deaths from coronavirus disease. This is indicated by a new study that analyzes what happened in 66 administrative regions in Italy, Spain, France and Germany, and which concludes that 78.5% of deaths from this disease occurred in only five regions, precisely those with...

Doctors are finding damage in kidneys, hearts and elsewhere by COVID-19

The coronavirus kills by inflaming and clogging the tiny air sacs in the lungs, choking off the body’s oxygen supply until it shuts down the organs essential for life. But clinicians around the world are seeing evidence that suggests the virus also might be causing heart inflammation, acute kidney disease, neurological malfunction, blood clots, intestinal...

Testing the association between blood type and COVID-19 infection, intubation, and death

A recent study of patients in China discovered an association between ABO blood type and SARS-CoV-2 infection status by comparing COVID-19 patients with the general population. Authors used observational healthcare data on 1,559 individuals tested for SARS-CoV-2 (682 COVID-19 positive) with known blood type in the New York Presbyterian (NYP) hospital system to assess the...

Hypertension in patients hospitalized with COVID-19 in Wuhan, China

A single-center, retrospective, observational study was conducted at Hankou Hospital, which is one of the hospitals designated to treat COVID-19 pneumonia patients in Wuhan, China. The criteria for suspected and confirmed cases of COVID-19 were based on the criteria previously established by the WHO. A total of 274 patients, 75 with hypertension and 199 without...

Overweight man: the perfect victim of the COVID-19

In Intensive Care Units (ICUs) in Paris, London or New York, the question arises time and time again: why does the coronavirus seem to target the obese male population so much? According to Dr. Matthieu Schmidt, from the Pitié-Salpêtrière hospital in Paris, they find in France a very large proportion of patients who are overweight...

Investigating the likely association between genetic ancestry and COVID-19 manifestation

The novel coronavirus 2019-nCoV/SARS-CoV-2 infection has shown discernible variability across the globe. While infected individuals from some countries have recovered relatively quickly with lower morbidities, those from some other parts of the world appear to remain affected for longer with slower recovery times and demonstrate relatively higher death/recovery ratios, something that is suggestive of a...

Temperature dependence of COVID-19 transmission

The data for the coronavirus disease in many different countries follow a common pattern: once the number of confirmed cases reaches order 10 there is a very rapid subsequent growth, which is well fit by an exponential behavior. The latter is typically a good approximation for the following couple of weeks and, after this stage...
