When a virus-carrying person coughs, sneezes, or speaks, respiratory droplets are generated that transmit the infection. A person close may inhale these droplets or they may land in their mouth or nose. You might contract the virus if you kiss someone or engage in other sexual activities and come into touch with their spittle.

How long will COVID-19 endure in contact with surfaces?
The duration of SARS-CoV-2 survival on various porous and non-porous surfaces has been investigated by numerous researchers 10, 11, 12, 13, 14, 15. Studies show that viable virus cannot be found on porous surfaces for minutes to hours whereas it can be discovered for days or weeks on non-porous surfaces. Compared to non-porous surfaces, SARS-CoV-2 appears to inactivate more quickly on porous surfaces, which may be due to capillary action and quicker aerosol droplet evaporation 16.
On typical non-porous surfaces like stainless steel, plastic, and glass, data from surface survival tests show that a 99 percent drop in infectious SARS-CoV-2 and other coronaviruses can be anticipated within 3 days (72 hours) of typical indoor environmental conditions. 10, 11, 12, 13, 15. However, real-world parameters such as initial virus amount (for example, viral load in respiratory droplets) and elements that can remove or degrade the virus, such as airflow and shifting environmental conditions, do not always reflect experimental settings on porous and non-porous surfaces. 8, 9. Additionally, they do not take into consideration the inefficiencies in the virus’s ability to move from surfaces to hands and from hands to mouth, nose, and eyes. 8, 9. Actually, investigations in the lab aim to maximize the recovery of viruses from surfaces (e.g., purposefully swabbing the surface multiple times or soaking the contaminated surface in viral transport medium before swabbing). The likelihood of fomite transmission after a person with COVID-19 has been in an interior space is minimal after 3 days (72 hours), regardless of when it was last cleaned 8, 9, 10, 11, 12, 13, 15, when taking into consideration both surface survival data and real-world transmission parameters.
Can you contract COVID-19 by touching something?
The virus, SARS-CoV-2, primarily travels from person to person. Exhalation causes people to expel respiratory fluids in the form of droplets in a variety of sizes, such as while speaking, singing, exercising, coughing, or sneezing. These droplets spread illness and carry viruses. Within seconds to minutes, the biggest raindrops swiftly depart from the atmosphere. Small enough to remain suspended in the air for minutes to hours are the tiniest very tiny droplets and aerosol particles that are created when these thin droplets rapidly dry.
Within three to six feet of an infectious source, where the quantity of these extremely small droplets and particles is highest, there is the greatest risk of transmission. The virus can enter your body if you swallow them or breathe them in. Even while some virus carriers don’t show any signs of illness, they might nevertheless pass the infection to others.
Although it is less common, you can potentially contract the virus by touching your mouth, nose, or perhaps your eyes after contacting a surface or object that has the virus on it. The majority of viruses can survive for a number of hours on a surface. According to a study, SARS-CoV-2 can survive for several hours on a variety of surfaces:
- 4 hours for copper (coins, tea kettles, kitchenware)
- Boxes for shipping made of cardboard: up to 24 hours
- 2 to 3 days Plastic (milk bottles, detergent bottles, bus and subway seats, elevator buttons)
- 2 to 3 days for stainless steel (refrigerators, cookware, sinks, some water bottles).
How long does the coronavirus disease take to recover from?
Early studies claimed that your body may recover from a mild illness in 2 weeks and from a serious or critical illness in up to 6 weeks. According to more recent statistics, recuperation differs for various persons depending on factors including age and general health. The symptoms that were most likely to linger were fatigue, headaches, and breathing difficulties.
According to CDC recommendations, you should confine yourself to your house while you recover from your illness.
- You haven’t taken a fever-reducer for a fever over the past 24 hours.
- Even though they might not entirely be gone, your symptoms are better.
- At least 5 days have passed since the onset of your symptoms.
Can you contract COVID-19 via a kiss?
The coronavirus is well known to infect the body’s airways and other areas, however recent findings suggest that the virus may also attack mouth cells. Kissing a COVID carrier is not advised.
Most people with COVID-19 are no longer contagious 5 days after they first have symptoms and have been fever-free for at least three days.
One of your first thoughts might be to be tested right away if you’ve been exposed to COVID-19. A false-negative result and, even worse, a false sense of security could occur from testing too soon during the incubation period.
The period of time between contracting an illness and developing symptoms is known as the incubation period. For COVID-19, that window might range from the first day following exposure to five days following the onset of no symptoms.
We are aware that trying to remember all the various suggestions and rules might be confusing. A timeline of COVID-19’s incubation phase is provided below, along with responses to some of your most pertinent queries. It’s crucial to see your doctor if you have tested positive for COVID-19 or have been exposed. They can keep track of your symptoms, decide on a course of treatment, and provide advice on testing and quarantine.

What kind of shelf life does COVID-19 have in the open air and on other surfaces?
According to a recent study published in The New England Journal of Medicine by researchers from the National Institutes of Health, CDC, UCLA, and Princeton University, the virus that causes coronavirus illness 2019 (COVID-19) is stable for several hours to days in aerosols and on surfaces. SARS-CoV-2 was shown to be detectable in aerosols for up to three hours, for up to four hours on copper, for up to 24 hours on cardboard, and for up to two to three days on plastic and stainless steel, according to the researchers. The findings indicate that SARS-CoV-2, which causes COVID-19 disease, is stable and that humans can contract it by breathing it in or by touching infected objects. After the researchers posted the details of the study on a preprint server in order to immediately share their findings with others, the study’s information has been widely disseminated during the previous two weeks.
The National Institutes of Health (NIH) scientists investigated how the environment impacts SARS-CoV-2 and SARS-CoV-1, which causes SARS, at the Rocky Mountain Laboratories site in Montana. Like its descendant, which is currently spreading over the world, SARS-CoV-1 originated in China and infected more than 8,000 people between 2002 and 2003. Through diligent contact tracing and case isolation procedures, SARS-CoV-1 was completely eradicated, and no new cases have been found since 2004. The human coronavirus that is most similar to SARS-CoV-2 is SARS-CoV-1. Sadly, the stability study’s findings that the two viruses behaved similarly leave us unable to understand why COVID-19 has grown into such a significant outbreak.
The goal of the NIH study was to simulate how a virus might spread from an infected individual to common surfaces in a home or hospital setting through coughing or touching objects. The duration of the virus’s contagiousness on various surfaces was then examined by the researchers.
The researchers noted the following additional findings from their research:
- Why are there more SARS-CoV-2 infections if the two coronaviruses are similarly viable? New information reveals that SARS-CoV-2 carriers may spread the virus before or before they even notice any symptoms. As a result, disease prevention strategies that were successful against SARS-CoV-1 might be less successful against its successor.
- SARS-CoV-2 secondary cases of virus transmission appear to be more common in community settings than in healthcare settings, in contrast to SARS-CoV-1.
- However, healthcare facilities are also susceptible to the introduction and dissemination of SARS-CoV-2, and it’s possible that the virus’s capacity to survive in aerosols and on surfaces helps disseminate it there.
The results support the advice of public health experts to take preventative measures akin to those for influenza and other respiratory viruses in order to stop the spread of SARS-CoV-2:
- Stay away from sick people’s close quarters.
- Don’t touch your lips, nose, or eyes.
- When you’re sick, stay at home.
- Use a tissue to cover your cough or sneeze, then discard the tissue.
- Use a common household cleaning spray or wipe to clean and disinfect commonly touched objects and surfaces.

The frequency of Paxlovid rebound.
Ho meticulously monitored his illness. In his lab at Columbia University, he had access to PCR testing, genetic sequencing, and fast antigen kits for at-home testing. He began taking Paxlovid the next day after developing cold symptoms and a positive antigen test result. Ho kept taking the prescribed daily therapy of two separate medicines for five days after a PCR test on day two confirmed the infection. His antigen testing came back negative every day from day 4 to day 9, and the two PCR tests that were run on days 5 and 7 likewise came back negative.
However, he experienced a headache, runny nose, and a light cough on day 10. Ho made the decision to test himself at home, and to his astonishment, a PCR test revealed that he was once more positive. His colleagues analysed the virus to compare it to the genetic sequence from his earlier infection and discovered that it was the same virus that he had been exposed to days before, indicating that the virus hadn’t changed to become resistant to Paxlovid or that he hadn’t contracted it again. After being contained for a few days, the same virus had returned with a vengeance.
“He recalls, “I was shocked to witness the rebound.” “I assumed Paxlovid would take care of everything.
How long before COVID-19 recovers?
The majority of persons appear to recover and stop testing positive around three days later without requiring more covid-19 therapy, and so far there have been no reports of severe sickness in those who have suffered covid return.
Should I refrain from touching anything when I’m shopping because of the COVID-19 pandemic?
According to research, respiratory droplets from people who are in close proximity to one another disseminate COVID-19 more frequently than contact with surfaces. While unlikely, it is nonetheless conceivable for those droplets to land on surfaces and for a person to become infected by touching their own mouth, nose, or eyes after having previously touched the surface (source). This issue can be resolved by often washing your hands with soap and water (or using hand sanitizer with alcohol as an ingredient). Wearing a mask and being at least 6 feet apart from others are two more crucial precautions to take when shopping to avoid contracting the illness.
