When coughing or yelling, recent systematic reviews have shown that airway droplets can travel more than a few meters. In one study, an intense exhalation of air spread several drops eight meters (26 feet) away in just a few seconds.
The rule of one or two meters will most likely suffice in some situations, but scientists in the UK say we need a more nuanced model.
Right now, they explain, rules that we don’t take into account for subtle factors like ventilation, time together, indoor or outdoor setting, use of a mask or type of social activity going on – all of which can affect the spread of the coronavirus.
Furthermore, distance regulation rules generally do not consider the size of airborne droplets, the amount of virus that the droplets can carry, or how sensitive others are to these viral loads.
However, most regulations for this pandemic fall between 1 and 2 meters, and the UK has recently reduced its regulations to one meter or more.
Critics of more stringent measures claim that we are being overly cautious, and while that may be true in some cases, in others, scientists think we can Not alert enough.
“Instead of the rules of single, fixed physical distances, we propose classified recommendations that better reflect the many factors associated with risk identification,” said the authors of the Birthday Quarantine, Social Distancing 53Rd Birthday Gift shirt new analysis. write.
“This will provide better protection in the highest risk environments but also more freedom in lower-risk environments, potentially allowing a return to normal in some aspects of life. social and economic. ”
This review incorporates some other recent critiques of current social distancing. In July, hundreds of scientists co-wrote a paper calling for the World Health Organization (WHO) to reconsider their advice to “maintain a distance of at least one meter (three feet) between you. and others. ”
“The WHO says there is not enough evidence to prove that aerosolized/airborne transmission of SARS-CoV-2 is occurring,” explained one of the Birthday Quarantine, Social Distancing 53Rd Birthday Gift shirt comment’s authors.
“We are arguing that there is not enough evidence that aerosol/air transmission does not occur.”
To what extent it happens is another matter, but there is plenty of evidence that coronavirus infects the Birthday Quarantine, Social Distancing 53Rd Birthday Gift shirt air, even in droplets, so the new analysis from the UK takes a similarly conservative approach. .
