CORONAVIRUS MIGHT SPREAD MUCH FARTHER THAN 6 FEET IN THE AIR
according to a recent study, air contaminated with the coronavirus (COVID-19) might travel four times farther the 6 feet.
Under the right condition liquid droplets from sneezes ,coughs and just exhaling can travel more than 26 feet and linger in the air for minutes.
HOW COUGH AND SNEEZE DROPLETS TRAVEL
A lot goes into how far the cloud and its droplets travel a person’s physiology ,the environment ,humidity and temperature ,the cloud can reach up to 26 feet for sneezes and less than that for coughs.When someone cough they can spray uo to 3000 droplets a sneeze could yield 40,000.
virus filled droplets smaller than a human hair ,The rapid international spread of coronavirus (COVID-19) suggests that using arbitrary droplets size cutoffs may not accurately reflect what actually occurs with respiratory emissions and lead to inadequate recommendation and more sick people. These droplets can be vey smalls small and invisible as the micron size to the ones that you can see that are on the order of the millimeter . A human hair is 60 to 120 microns thick.
droplets containing virus reach air circulation systems ,pathogen in the cloud potentially reach air circulation systems inside buildings ,there was sampling done in air vents with positive detection of the virus.Now there are other question about whether the detected virus particles are still live.however finding the virus in air vents is more compatible with that longer distance range that can be reached through the cloud.
Fresh air can help rid coronavirus droplets,These findings heighten the dangers for those caring for COVID-19 patients without sufficient air circulation to disperse the cloud its concentrated payload to droplets can linger in hospitals and homes. wWhen one is outside with air circulation or wind th e cloud and its payload is easily dispersed and less concentrated making sure that indoor spaces are aired frequently also reduces the concentration.
Masks protect against floating droplets ,Surgical masks are helpful at blocking large droplets but unlike respirators they do not provide a reliable level of protection from inhaling smaller airborne particles .N95 respirators are tight-fitting and filter out at least 95% of airborne particles as small as 3.0 microns.They have a protection factor (APF) of 10 .Means the N95 reduces the aerosol concentration to 1/10 of that in the room.
Should make a homemade face mask ? The CDC now recommends wear cloth face covering in public setting where it’s difficult to stay at least 6 feet apart. such as grocery stores ,pharmacies.
All this time ,loss of sense of smell and taste are primary symptoms .If you are experiencing either of these ,would highly recommend to self-isolated
