Current evidence suggests that COVID-19 spreads between people through direct, indirect (through contaminated objects or surfaces), or close contact with infected people via mouth and nose secretions. These include saliva, respiratory secretions or secretion droplets. These are released from the mouth or nose when an infected person coughs, sneezes, speaks or sings, for instance. People that are in close contact with an infected person can catch COVID-19 when those infectious droplets get into their mouth, nose or eyes. As global cases of covid-19 continue to soar and other people with symptoms are expected to be isolated from others, it’s no surprise that a growing number of folks flinch once we hear someone cough, even though they’re 2 meters away – the minimum separation that health officials advise. Research conducted on the new coronavirus and others similar to it, like SARS, suggest the virus can spread through particles within the air and via contaminated surfaces. How does this happen? Moreover, how long can the virus survive on surfaces and what can we do to guard ourselves? Covid-19 is a respiratory disease and is essentially spread via droplets within the air. These are typically expelled when an infected person coughs or sneezes. Although, if you are a student and you’re not able to write your assignment due to lack of resources in this lockdown, don’t worry.

Moreover, touching contaminated objects then infecting ourselves with the germs isn’t typically how the virus spreads. But it can happen. Fears about catching the coronavirus from contaminated surfaces have prompted many folks to spend the past few months wiping down groceries, leaving packages unopened and stressing about touching elevator buttons. But what’s the important risk of catching Covid-19 from a germy surface or object? The question has been on people’s minds lately, and there was some confusion after the Centers for Disease Control and Prevention made some edits to its website last week. Social media sites and a few news outlets suggested the agency had downgraded its warnings which surface transmission was not a worry. Although, the C.D.C. subsequently issued a news release to clarify that indirect contact from a contaminated surface — what scientists call fomite transmission — remains a possible risk for catching Covid-19. “Based on data from lab studies on Covid-19 and what we all know about similar respiratory diseases, it’s going to be possible that an individual can get Covid-19 by touching a surface or object that has the virus thereon then touching their own mouth, nose or possibly their eyes,” the agency wrote. “But this isn’t thought to be the way the virus spreads.” So does this mean we can catch coronavirus from touching a doorknob? Catching a Frisbee? Sharing a casserole dish? The solution, in theory, is yes, which is why you need to wash your hands often and avoid touching your face. a variety of studies of flu, rhinovirus, coronavirus and other microbes have shown that respiratory illnesses, including the new coronavirus, can spread by touching contaminated surfaces, particularly in places like day care centers, offices and hospitals.
However, what they’re saying is that high touch surfaces like railings and doorknobs, elevator buttons aren’t the first driver of the infection. But it’s still a nasty idea to touch your face. If someone who is infectious coughs on their hand and shakes your hand and you rub your eyes — yes, you’re infected. Someone’s drinking from a glass, and you pick it up near the rim and later rub your eyes or mouth, you’re infected. Here’s how fomite transmission works. An infected person coughs or sneezes on their hands. A number of the droplets may splash onto a close-by surface, or the person spreads the germs by touching a faucet or countertop before washing his hands. Studies show that coronavirus can last up to 3 days on plastic and steel, but once it lands on a surface, the quantity of viable virus begins to disintegrate in a matter of hours. Which means a droplet on a surface is way more infectious right after the sneeze — not such a lot a couple of days later. Next, you’ve got to come along and touch the contaminated surface, acquire enough viable virus on your hands, then touch your eyes, nose or mouth. If all goes well for the virus, you’ll get sick.
Furthermore, there’s an extended chain of events that might need to happen for somebody to become infected through contact with groceries, mail, takeout containers or other surfaces. The last step in the causal chain is touching your eyes, nose or mouth together with your contaminated hand, therefore the best way to ensure the chain is broken is washing your hands. A virus associated with a mall in Wenzhou, China, may have been fueled by fomite transmission. In January, seven workers who shared an office in a mall became ill when one amongst their co-workers returned from Wuhan. The mall was closed, and public health officials tracked 24 more sick people, including several women who had shopped at the mall, also as their friends. None of them had contact with the first sick office workers. The researchers speculated that a women’s restroom or the mall elevators had been the source of transmission.
Thereafter, other studies have used invisible fluorescent tracers — fake germs that glow under black light — to trace how germs are spread from surfaces. The findings are unnerving. In one series of experiments, 86 percent of workers were contaminated when spray or powder tracers were placed on commonly touched objects in an office. When tracer powder was placed on a bathroom faucet and exit doorknob, the glowing residue was found on employees’ hands, faces, phones and hair. From a shared phone, the tracer spread to desktop surfaces, drinking cups, keyboards, pens and doorknobs. A contaminated copy machine button added a trail of fluorescent fingerprints transferred to documents and computer equipment. Also, just 20 minutes after arriving home from the office, the fake germs were found on backpacks, keys and purses, and on home door knobs, light switches, countertops and kitchen appliances.
In conclusion, Hand washing is vital not just for fomite transmission, but also for person-to-person transmission. The respiratory droplets we produce when speaking, coughing and sneezing fall mostly onto our hands, and may fall onto other people’s hands if they’re within six feet from us. To avoid contact with these droplets, it’s important to remain a minimum of 1 meter faraway from others, clean hands frequently, and cover the mouth with a tissue or bent elbow when sneezing or coughing. When physical distancing (standing one meter or more away) isn’t possible, wearing a cloth mask is a crucial measure to guard others.
Eventually, I think the C.D.C. is correct when it says that surface transmission isn’t a dominant one. Surfaces frequently touched by an outsized number of individuals, like door handles, elevator buttons, etc., may play a more significant role in spreading the infection than objects touched incidentally, like food packages delivered to homes. The bottom line is that the simplest way to protect ourselves from coronavirus — whether it’s surface transmission or close human contact — continues to be social distancing, washing our hands, not touching our faces and wearing masks.
