Can I still infect others after wearing a mask if I have a cold?

If you wear a mask when you have a cold, you will not infect others with a cold under normal circumstances, so you don't have to worry too much, but you should usually do a good job and actively improve the situation of the cold. Cold viruses are usually transmitted by respiratory droplets, and wearing a mask can prevent respiratory foam from spreading from the mouth or nose, which can effectively prevent infection.

If you have a cold, you will basically not infect others after wearing a mask, because you can still block the cold bacteria, unless the quality of your mask is not up to standard.

It is still possible to infect others after wearing a mask after catching a cold, because the mask cannot 100% prevent people from spitting.

Well, if you wear a mask again, it's basically very unlikely that you can just pass it on to others.

Wearing a mask after you have a cold can greatly reduce the chance of infecting others.

If you have a cold, it is normal to infect others with a mask.

If I have a cold, will I still infect others after wearing a mask? I feel like I'm trying to stay away from people.

Summary. Take the new coronavirus as an example, healthy people wear masks and infected people do not wear masks, the probability of infection is 30%; Healthy people do not wear masks and infected people wear masks, and the probability of infection drops to 5%. If neither the healthy nor the infected person is wearing a mask, the probability of infection is as high as 90%.

If both healthy people and infected people wear masks, the virus transmission rate is only there, and when both wear masks and the effective protection distance is greater than meters, then the probability of infection will be reduced to 0%. Although wearing a mask cannot prevent 100% virus infection, it can play a certain role in prevention, especially in closed and crowded environments. Wearing a mask can prevent harmful substances such as viruses from the outside from entering your respiratory tract, and at the same time, you can also avoid droplets from entering the air when you talk or cough, which can effectively reduce the risk of virus transmission.

Is it contagious if one wears a mask and the other does not wear a mask.

I'm sorry I don't understand, but can you elaborate on that?

Wearing a mask can prevent harmful substances such as viruses from the outside from entering your respiratory tract, and at the same time, you can also avoid droplets from entering the air when you talk or cough, which can effectively reduce the risk of virus transmission.

The novel coronavirus is highly transmissible and has been confirmed to be mainly transmitted through droplets and contact, and the transmission route of aerosols and digestive tract has yet to be clarified. From the perspective of preventing droplet transmission, wearing a mask can have a certain preventive effect, but as for chatting with an infected person for a short time, is there a high chance of being infected? According to the characteristics of virus transmission, whether or not to be infected is mainly related to the following three points:

1.Types of masks

First of all, it depends on the type of mask to be worn, and the masks recommended by the state mainly include ordinary medical masks, medical surgical masks and medical protective masks. From the perspective of the protective performance of the mask, it is best to use a medical protective mask, which is mainly used by medical staff to wear in fever clinics or when treating new crown pneumonia patients. The protective performance of ordinary medical masks is average, and they are only suitable for daily wear when the general public has not been in contact with patients infected with the new crown.

From the analysis of the above problems, the situation is already close contact with the new crown infected patients, even if it is just a short chat, then according to the protection requirements, it is necessary to wear a medical protective mask, so that the probability of being infected will be relatively small, but if you only wear an ordinary medical mask, then the probability of being infected is greater.

2.The virus can be spread in other ways

Secondly, it is possible for the virus to spread through the conjunctiva of the eye. A short chat with an infected person, although both parties are wearing masks, droplets from the infected person or the contaminated hands of the contact person are not washed in time, which may cause the virus to spread through the conjunctiva of the eye and cause infection, which is why medical staff also need to wear goggles when treating new crown pneumonia patients, and if they do not wear goggles, they will also increase the chance of infection.

3.Contact distance from an infected person

No matter a person talks, coughs, or sneezes, there is undoubtedly the densest number of droplets within a radius of meters, so experts recommend that regardless of whether you wear a mask or not, it is best to keep a distance of at least one meter when chatting with people to avoid close contact, the closer the distance, the greater the chance of being infected.

Therefore, even if you wear a mask, there is no guarantee that you will not be infected 100%. Of course, since the incubation period or asymptomatic infected people can become the source of infection, if you are sure that you have been in contact with an infected person, even if it is only a short chat and wearing a mask, in order to avoid the re-transmission of the virus, you need to be isolated and observed first, and if possible, you can take a nucleic acid test to confirm whether you are infected by the new coronavirus. Whether or not you will get sick after being infected depends on the patient's immunity, and young people with good immunity may not necessarily get sick.

It's going to get infected. The chance of getting infected while wearing a mask is reduced. Do not come into close contact with an infected person!
