Coronavirus Surface Transmission – Facts vs Myths

As the pandemic continues to rise to its peak, we are getting more and more familiar with the newly born coronavirus (COVID-19). This world threat has concentrated all of the masterminds from the entire world around the same periphery. From small to big research centers, all are actively involved in decoding the coronavirus, some of them are trying to sort out the vaccine problem, and some are dealing with various antidotes, while some are still exploring more and more information about COVID-19. Especially, coronavirus surface transmission reality & myths.

This Nobel coronavirus has a very high transmission rate and since WHO has declared that the vaccine formation will take nearly 18 months to be available to the public. So we have to start adapting ourselves to make our defense strong against coronavirus transmission.

As long as the vaccine is not ready for us we should know that the virus will always be one step ahead of us. So we have to be more and more cautious to weaken its every attack.

The virus can transmit among people by as simple means as possible. Generally it gets transmitted from an infected person from small droplets of saliva when he or she sneezes or just talks.

However the tendency of viruses to remain alive for a long time on the surfaces has exaggerated its transmission rate even more, and coronavirus surface transmission has become a major concern for the peoples to know that how many days the virus can be alive on different surfaces.

How long does coronavirus live on surfaces?


Some Researches on Surface Transmission of coronavirus (COVID-19)

According to the latest research on the virus life span on different surfaces in a 71-degree-Fahrenheit room at 65%relative humidity, the virus lasts in different surfaces from few hours to few days

Coronavirus on Printing and Tissue Paper
  • The COVID-19 virus can live up to 3 hours
Coronavirus on Wood and Cloth Fabric
  • The COVID-19 virus can live up to 2 days
Coronavirus on Glass or paper Money
  • The COVID-19 virus can live up to 4 days
Coronavirus on Stainless steel and plastic
  • The COVID-19 virus can live up to 7 days


Even researchers published the interesting fact about coronavirus surface transmission that coronavirus (COVID-19) can live upto 7 day on Surgical mask

However the study is still going on whether the virus they found on the mask after 7 days can infect someone or not.

In the earlier research which was published on March 17 in the New England Journal of Medicine. The virus was tested in a similar condition of the 70-degree-Fahrenheit room at 40% relative humidity.

And here are the results.

The COVID-19 virus can live up to 4 hours on Copper
The COVID -19 virus can live up to 1 day on Cardboard


COVID 19 verses SARS coronavirus

This Nobel coronavirus has a very close resemblance to SARS-CoV. Hence researches are parallelly going on for both viruses to get some boost in research.

According to the Journal of Hospital Infection published on March 1, 2020, the SARS coronavirus at a temperature of 68 degrees Fahrenheit lived in

In Aluminum,

the SARS virus can live up to 2-8 hours

In Steel,

the SARS virus can live up to 2 days

In Wood and glass,

the SARS virus can live up to 4 days

In Metal, plastic, and ceramics,

the SARS virus can live up to 5 days


Coronavirus on Food

We don’t fully understand the various modes of coronavirus surface transmission of the COVID-19 yet, we are still getting updated about it daily. According to Ben Chapman, a professor and food safety specialist at North Carolina State University, there is no evidence of transmission of the virus from foods. however, the food packages in the grocery store might be the carrier but we can easily mitigate that risk by properly washing our hands after handling the packages.


Effect of temperature on coronavirus

According to the Lancet study:

At 4 degree Celsius in a test tube == the virus was alive for 2 weeks

At 37 degree Celsius in a test tube == the virus was alive for only 1 day

This shows that the virus is weaker in the hot regions and will be much more devastating in the colder regions.

Unfortunately there are no shreds of evidence that the virus cannot be transmitted in Hot and Humid weather. It is transmitting in all areas regardless of the climate.

So the activities like taking a hot bath with extremely hot water and exposing yourself under the sun for the whole day will eventually put you in health risk instead of killing the virus.

Our normal body temperature is 36.5 to 37 degree Celsius regardless of the climate and temperature of your bath.

So, the only known way to protect yourself against the infection is by frequently cleaning your hands.


Disinfecting the surfaces from Coronavirus

The journal of hospital Infection study noted that

The solution that contains 62%-71% ethanol alcohol, 0.5% hydrogen peroxide, or 0.1% sodium hypochlorite, can efficiently inactivate the human coronaviruses within one minute.

Use them wisely to keep you protected against the new coronavirus.


Simple Precautions to protect yourself against Coronavirus pandemic

According to Dr. Iwasaki only one viral particle on your hands you are not likely to be infected. But for some potent viruses 10 particles are enough to get you infected.

According to the Journal of hospital infection, if you touch the infected surface for 5 seconds then 32% of the virus living on that surface could transfer to your hands.

And Graham said “Most humans touch their faces several hundreds of times per day.

So now is the time to change your habit a little bit. Try not to touch your hands in your face. Because your eyes, nose, and mouth are the major pathways for the virus to enter into your body.

CoronaVirus related myths, solved by the World Health Organization

  • Can you hold your breath for 10 seconds or more without coughing or feeling discomfort? If you can do so, that’s ok. But it does not mean that you are free from coronavirus.
  • Drinking alcohol cannot protect you against the coronavirus. But the excessive consumption might help you put in health risk.
  • The novel coronavirus does not transmit through mosquito bites.
  • Hand dryers are not effective in killing the coronavirus. However you can often use them to dry your hands after cleaning them properly.
  • An ultraviolet disinfection lamp cannot kill new coronavirus instead it can cause you the skin irritation.
  • A thermal scanner can only detect the high fever that is the symptom of the new coronavirus.
  • It cannot detect the coronavirus if the person is infected but completely healthy.
  • Spraying alcohol or chlorine all over your body won’t help you kill the new coronavirus if it is already entered into your body. Instead it can harm our mucous membranes severely.
  • People of all ages are equally susceptible to the infection of the coronavirus, however, older people and the people with preexisting medical conditions (like heart diseases, diabetes, and asthma) can appear vulnerable to severe illness.
