Away from home
Crowding buses, taking the subway, staying in hotels...
It is inevitable that there will be times when you sit on a hot bench
But recently
#Why can't you sit on someone else's hot stool#
Rushed to the hot search
A netizen asked a question, saying that someone got off the bus and a boy next to him wanted to sit, but was reminded by an aunt on the bus to wait for the seat to cool before sitting. I heard my mother say something similar, and I wonder why?
The topic quickly sparked discussion
Some netizens said
You can't sit on a hot stool that someone else has been sitting on
It is because there is a possibility of contagious diseases
Truly anecdotal
And there are many netizens who think so
But
Some netizens think
There is no scientific basis for this claim
Is there a risk of contagious disease when sitting on a hot stool?
Most of the disease pathogens transmitted by contact often do not survive long in dry and hot environments, and they often need sufficient quantity and activity to penetrate the skin barrier.
Therefore, as long as a person's skin barrier is intact, it is difficult for the residue on these benches to pose a threat to the individual's health.
However, there are some pathogens, such as chickenpox, cutaneous candidiasis, scabies, ringworm and other diseases, if the patient's skin site is directly in contact with the bench, and directly touches the skin of the next person without complete inactivation, there is a possibility of infection.
Chief physician Pan Hongying, director of the Department of Infectious Diseases of Zhejiang Provincial People's Hospital, said that no matter what kind of infectious disease, the transmission route is the key, such as contact transmission, blood transmission, respiratory transmission, etc., and simple "stool fever" will not cause infection.
Now that the weather is getting hotter and everyone is dressed cooler, assuming that the pathogen is to be transmitted through stools, the most likely is contact transmission, but this contact also has preconditions.
For example, if the skin of the previous person sitting on the stool directly touches the stool, the surface of the seat may leave its dander, sweat, sebum and some germs on the surface of the skin. The latter person sits up immediately after the other person leaves, and may be exposed to these germs.
Pan Hongying said:
It is not that you will be infected if you contact germs, most pathogens transmitted by contact are sensitive to temperature and humidity, and will die quickly after leaving the human environment, and it is very unlikely that they need sufficient quantity and activity to penetrate another person's clothing and skin barrier, so there is no need to worry too much.
Of course, it does not mean that this risk does not exist at all, such as a patient with chickenpox, skin candidiasis, scabies, ringworm and other diseases because of the skin affected area, left body fluids on the seat, someone happened to sit in this position immediately after he left, and unfortunately there is also skin damage in the contact with body fluids, then there is still the possibility of infection.
What should I pay attention to when touching public facilities?
For regularly cleaned, dry and hygienic public places, there is not much risk of infectious diseases. However, when touching public facilities, you still need to pay attention to the following points:
1. Keep away from places with humid and poor cleaning conditions.
Some places, such as public restrooms, have poor cleaning conditions and are relatively humid, which is easy to become a breeding ground for germs, or try to stay away.
2. Wash your face and hands as soon as you go home.
Airborne dust tends to settle in the pores of the skin, and hands can come into contact with a large number of public facilities every day, and in the absence of cleaning, contact with the nose and mouth is often prone to spreading pathogens. Therefore, washing hands frequently and using hand sanitizer with a bactericidal effect can better protect personal hygiene.
3. Pay attention to avoid occasions where many people gather.
In an environment with many people and poor ventilation, wear a mask, and if you cough and sneeze, pay attention to cover your mouth and nose to protect yourself and others.
