A meme is circulating on the Internet comparing the statement once COVID-19 is over to the wishful possibility of winning the lottery.
Both might seem very out of reach, but continuing to remain vigilant with frequent handwashing, social distancing, mask-wearing, and cleaning especially as summer winds down and schools reopen could eventually make a difference with the coronavirus pandemic, experts say.
Ernesto Abel-Santos, a professor of biochemistry at UNLV who studies bacteria such as anthrax and the hospital infection, Clostridium difficile (C-diff), said we should continue to be as careful as possible with the daily choices we make, and the activities we partake in as the pandemic continues to persist.
While social distancing, handwashing, and donning a face covering continue to be the most prudent actions people can take, Abel-Santos said being attentive to frequent cleaning is also a critical tool in our arsenal especially in classrooms with students coming and going.
Here, Abel-Santos provides cleaning best practices to keep virus germs at bay.
Frequent handwashing is still the most important action you can take to help prevent the spread of COVID-19. That, combined with social distancing and wearing a mask in the absence of an effective treatment, or a vaccine are the three most vitalthings you can do.
The main way of contracting COVID-19 is through person to person contact. So if someone is sneezing, coughing, talking or singing, it produces aerosols from your mouth, and thats the way that most people contract it.
The virus can also linger on surfaces from hours to days, depending on the surface. We should clean surfaces often, but how often depends on the usage of the area.
Classrooms, for example, where a group of students come in, leave, and then another group follows, should be cleaned after every class. Every person should be responsible for cleaning their desk before leaving. And if youre the person coming into the class, you should disinfect too, because you dont know if the person before you did.
Masks must also be decontaminated continually. People should either use single-use disposablemasks or wash their clothmasks at the end of the day. Cloth masks should be treated as undergarments change them daily.
The virus can stay on cardboard for up to 24 hours. It can stay on copper surfaces for up to four hours, but can linger for two to three days on plastic and stainless steel surfaces. It can hang in the air around you for up to three hours.
Copper tends to be more reactive, so it is able to kill the virus quicker. Rigid surfaces like plastic, stainless steel and perhaps even marble, provide a better environment for the surface to survive. But there are still a lot of things we dont know, which is why we have to be as careful as possible and clean often.
You have to ask yourself, what is the likelihood that a given surface is exposed? If youre isolated at home, and you minimize going out and avoid bars, churches, gyms, or other areas where people congregate in large amounts, your risks are diminished, and you would not need to decontaminate surfaces as frequently. If youre sharing an office, or work in an office where people are continuously coming in and out, you have to clean more often. An office at the end of a hall behind a partition does not pose the same risk as a receptionist coming into contact with multiple people.
COVID-19, like other viruses, are actually quite weak and wimpy outside of the body. You can neutralize them with alcohol. Detergents with quaternary ammonium salts are also effective.
Any disinfectant will kill viruses. But again, one of the most effective strategies is washing your hands. You dont realize how many times in a day you touch your face with your hands. If you touch a surface and then touch your face, it increases the probability of contagion.
One word of caution. You have to be careful right now because theres been a huge increase in alcohol based sanitizers. Manynew companieshave popped up to fill thedemand, but some companiesare adulterating the alcohol content.
Some are using methanol, which is a wood alcohol. Skin exposure is not that bad, but if children get into it, and ingest it, it can cause blindness.
That depends on the disinfectant. Alcohol-based disinfectants, for example, evaporate very quickly. After a few seconds, its gone.
Every disinfectant will list directions on the bottle with its recommended usage. Its important to read the manufacturer directions carefully and follow the directions correctly.
I would not, unless its recommended by the manufacturer. You can use gloves when youre using something like bleach, but thats to protect you from the bleach more than anything else. We use gloves in laboratories, but its not recommended in houses.
Gloves are also counterproductive in situations like shopping in a supermarket. In a lab environment, we use gloves all the time, but we have boxes and boxes of gloves and we continuously change them out.
Once you touch a surface, your gloves are going to be contaminated. Its the same thing if you touch the surface with your bare hands. If you touch your face with a contaminated glove, its going to carry the same risk of catching the virus as if you touched your face with your bare hand.
Quite simply, you cannot. You hope that everyone is taking it seriously and that everyone is following procedures given by the CDC (Centers for Disease Control and Prevention) and the World Health Organization on how to disinfect and keep things safe, but its not a guarantee.
If youre going to go out, I would recommend bringing a small spray bottle of disinfectant and wipe the area. But the ways things are going now, I wouldnt recommend going to places like gyms, bars, movie theaters, or other areas where large numbers of people are congregating.
Cleaning surfaces is important, but it is secondary to measures like social distancing, wearing masks, and washing your hands.
