10 post COVID-19 trends

There will be a before and after of this confinement. The return to normalcy so longed for by many will not be a return to the previous daily routine. Now we are all experts in epidemiology and coronavirus (COVID-19). We are hyperinformed, even info-informed, because unfortunately not all the information we receive is real and...

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...

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...

Italian researchers isolate COVID-19 virus in tears

Human-to-human transmission occurs mainly through respiratory droplets, but other routes are under investigation, because SARS-CoV-2 has been detected in several body fluids. With regard to COVID-19, unprotected ocular exposure was thought to be responsible for infections that occurred in the Wuhan Fever Clinic in January 2020; in addition, SARS-CoV-2 RNA was detected in conjunctival secretions...

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...

Surgical and N95 masks

The rapid global spread of SARS-CoV-2 and the resulting coronavirus disease (COVID-19) pandemic has led to urgent efforts to contain and mitigate transmission, leading to significant and widespread socioeconomic disruption. As of April 3rd 2020, over one million cases have been reported worldwide, as well as over 60,000 deaths, with ongoing spread in most parts...

COVID-19 outbreak associated with air conditioning in restaurant

A new publication studies what happened in a restaurant and how air conditioning, an ordinary element in any place that serves food, could have helped infect at least nine people with COVID-19. This is the first work to suggest that air conditioning could play a role in COVID-19 transmission. The analyzed date took place on...

City size and COVID-19 attack rate

The current outbreak of novel coronavirus disease 2019 (COVID-19) poses an unprecedented global health and economic threat to interconnected human societies. Until a vaccine is developed, strategies for controlling the outbreak rely on aggressive social distancing. These measures largely disconnect the social network fabric of human societies, especially in urban areas. A new study estimates...
