Assmmm Want to ask doc..I have a gas mask .. Can it be used for covid prevention 19..rims ..
Wa alaikumsalam, thank you for asking at HealthReplies.com. The WHO has indeed updated their advice on tips for preventing corona virus infection, and that is by continuing to wear masks regardless of whether the person is sick or not. This is based on the large number of people who are infected with corona but show no symptoms, so that even though he is not feeling sick, he can still transmit the virus to others.
Regarding your question, gas masks can be used to prevent corona virus infection, but this is no more effective than other methods, such as the use of surgical masks, N95 masks or cloth masks. For medical staff who deal directly with patients who may cough, sneeze or even vomit before them in the condition of the patient who is unconscious, surgical masks, N95 and cloth masks certainly have a significant difference in protection, but for ordinary people to carry out daily activities outside the room, actually cloth masks that can now be easily obtained or made by yourself are enough.
But if you really want to use a gas mask, pay attention to the filter. Because there are various kinds of filters from gas masks that can have different levels of density and filtering. If you happen to not have a filter, or the density level is low, it is not impossible that the effectiveness is actually lower than a fabric mask.
But apart from that, the use of masks is actually more aimed at avoiding transmission from droplets, which are grains of invisible water vapor that come out of the mouth when someone coughs, sneezes or talks. But the use of masks does not protect you from being infected with this virus through hand contamination. So you also need to understand that it is still important to maintain hand hygiene by routinely washing your hands by following the WHO recommended hand washing steps before touching your eyes, nose or mouth. So, hopefully answering your question.
