Fist Bumps vs. Handshakes: How COVID-19 Does/Doesn’t Spread


With greater than 73,000 folks confirmed with COVID-19 an infection as of Feb. 18, and almost 2,000 deaths world wide, questions on how the virus spreads have gotten extra pressing.

Right here’s what you must bear in mind: COVID-19 spreads when the virus liable for the illness, SARS-CoV-2, a coronavirus, is transmitted by one particular person to a different in respiratory droplets. Which means the virus can unfold when an contaminated particular person coughs or sneezes and releases these droplets into the air, the place they’re both inhaled by others, or can land on different folks’s mouths or noses in the event that they’re close to sufficient—typically a distance of about six ft (1.eight meters). As soon as the virus finds itself inside a brand new human host, it will possibly begin infecting cells and trigger illness.

The opposite factor to bear in mind is that whereas medical doctors are nonetheless studying about how this explicit coronavirus behaves within the human physique, evidently SARS-CoV-2 is extra doubtless transmitted when the contaminated particular person already has signs of COVID-19, together with fever, cough and shortness of breath. Primarily based on the instances described up to now, medical doctors imagine it might take SARS-CoV-2 wherever from two to 14 days to trigger signs, so for now, they’re assuming that the virus will be unfold at any time throughout that interval.

Is it higher to fist bump or handshake to keep away from getting COVID-19?

Because the illness spreads by way of respiratory droplets, neither a handshake or fist bump can be a major technique to go alongside the virus. An contaminated particular person must sneeze or cough into his hand, contact another person’s hand, and that second particular person would then have to put that hand in shut contact with their nostril, mouth and even eyes to get contaminated with any virus which may nonetheless be on the hand’s floor. So there’s no actual motive that fist bumps are any safer than shaking arms in terms of COVID-19. And no motive to keep away from shaking arms for that matter both.

Are you able to get COVID-19 by touching contaminated doorknobs, doorhandles or objects?

As with handshakes, touching contaminated surfaces isn’t a significant supply of transmission, for the reason that SARS-CoV-2 virus is most effectively unfold by respiratory droplets. Nonetheless, if the virus lands on a floor after an contaminated particular person coughs or sneezes, and one other particular person touches that floor quickly afterward after which touches their nostril, mouth or eyes, there’s a small chance the virus may very well be transmitted. Specialists aren’t positive but how lengthy the virus can survive on such objects, however for viruses on the whole, it’s not very lengthy.

Are you able to get COVID-19 by using in the identical aircraft, bus or subway as an contaminated passenger? What about sitting in a movie show or enviornment with somebody who’s contaminated?

It’s all about proximity. Since COVID-19 is unfold by respiratory droplets, the vital and limiting issue is how far these droplets can journey when somebody sneezes or coughs. Usually, consultants say that’s about six ft, or a bit underneath two meters. Which means that the folks sitting closest to an individual contaminated with SARS-CoV-2 are at highest threat of getting contaminated.

In a public place, what’s the easiest way to guard myself from getting contaminated?

In the intervening time, consultants on the U.S. Facilities for Illness Management and Prevention (CDC) don’t suggest that wholesome folks put on face masks in public. For now, it’s extra vital for people who find themselves contaminated to contemplate sporting them with their physician’s suggestion so as to forestall spreading the virus to well being care staff and others who’re bodily near them.

There are a number of several types of masks. Disposable paper masks may help to cut Back the possibilities of spreading contaminated droplets, and they need to be thrown out after every use. Masks like N95, named as a result of they’re designed with higher filters to dam about 95% of small particles folks breathe in, are meant for well being care staff who’ve extra direct and sustained contact with contaminated sufferers and are at larger threat of being uncovered to SARS-CoV-2. However for most individuals, the CDC is at present not recommending the usage of both kind.

For wholesome folks, frequent hand-washing is among the greatest methods to push back SARS-CoV-2, since that may take away any virus-containing droplets in your arms that would make it to your nostril or mouth. Well being officers say utilizing cleaning soap and water must be the primary selection for laundry arms, for the reason that lather created by scrubbing your arms with cleaning soap can dislodge germs successfully. Specialists have not too long ago backed away from recommending alcohol-based hand sanitizers; though they’re efficient in killing some germs, they will additionally contribute to the rise of antibiotic-resistant micro organism which might be more durable to deal with and kill.

And for many who are sick, protecting coughs and sneezes with a tissue is one other essential technique to forestall any virus, not simply SARS-CoV-2, from touring to a different particular person.
