DenpaNews The use of masks to prevent transmission of COVID-19 is allegedly ineffective if those who wear them are healthy people. Instead of wearing masks, people are advised to maintain personal hygiene and limit contact with sick people. The reason is, the spread of some diseases caused by coronavirus does not pass through the air ( airborne ), but droplets .
The spread of disease through the air and droplets are often associated with each other. Although similar, the two have some differences. The ability of transmission, the distance of spread , and the disease that is transmitted can also be different between the two. So, what are the differences?but now we know the omicron variant
Know the various methods of spreading disease
Bacteria, viruses, and causing germs can be transmitted in various ways. Transmission of disease in the medical world is known as transmission. Each type of germ can spread by different transmission methods.
Launching the American Animal Hospital Association , so far it is known that there are five types of transmission, namely:
Direct contact with the patient’s tissues or body fluids. Germs of disease enter the body of a healthy person through the eyes, mouth, or open wounds.
By air, either directly ( airborne ) or droplet . Airborne and droplet usually occurs in respiratory tract diseases .
Orally from contaminated food, water, or item surfaces. Germs are usually found in the feces , urine, or saliva of patients.
Through vectors, namely living things that can spread diseases such as mosquitoes, fleas, rats, and so on.
Zoonoses, which means from animals to humans. Zoonotic transmission can occur through direct contact, air, vector, or oral.

Of the various types of transmission, spread by direct contact is the most common and the risk is very high. However, airborne spread also needs to be watched out for because it can cover many people at once.
The difference between the spread of disease through the air and droplets
The spread of disease through the air occurs when a sick person talks, coughs, or sneezes thereby expelling germ particles from his body. The germs then fly in the air and stick to the eyes, mouth, or nose of healthy people.
If germs are spread through the air, disease transmission can occur even if the patient does not have direct contact with a healthy person. In fact, germs can spread into the air when the patient exhales.
Because germs can survive in the air, airborne transmission tends to be difficult to control. This is why airborne such as chickenpox and tuberculosis are more difficult to prevent and treat. Transmission is also fairly fast and covers a wide area.
The spread of disease through the air and droplets are often considered the same. Though, there is a difference between the two. spread Droplet occurs when a sick person coughs or sneezes, releasing droplets containing germs.
If a splash of liquid containing germs enters the eyes, mouth, or nose of a healthy person, that person can contract the disease. This method of transmission occurs in colds, Ebola infection, and COVID-19 which is currently endemic in several countries.
Prior to COVID-19, the most severe outbreaks similar to the spread of SARS-CoV-2 were MERS and SARS. Both diseases that attack the respiratory system are also known to spread through droplets , not air. For example, the spread of SARS and MERS occurs through close person-to-person contact. prevent too from hit by omicron.
However, recently the WHO has appealed to medical workers to increase their vigilance because the COVID-19 virus is thought to be able to survive in the air . Although the power of the virus may not be able to infect other people, you still need to be vigilant by maintaining a distance.
dispersal Droplet is usually limited to one meter. However, droplets can also stick to surfaces, especially doorknobs, cell phones, and banisters. You run the risk of contracting the disease if you touch contaminated items and then touch your eyes, nose or mouth without washing your hands with soap
Prevent the spread of disease through the air and droplets
disease Airborne is very difficult to prevent, but you can reduce your risk of contracting COVID-19 by taking the following steps:
- Limiting close contact with people showing symptoms of COVID-19 .
- Stay home when you are not feeling well.
- Cover mouth and nose with a tissue when coughing or sneezing. If you don’t have a tissue, use your sleeve to cover your mouth and nose.
- Wear a mask if you have to be in a crowd.
- Do not touch your face or other people before washing your hands.
- Wash your hands regularly for at least 20 seconds, especially after coughing or sneezing.
You can also do a similar way to prevent disease transmission through droplets . However, the best way to actually prevent it is to wash your hands regularly and limit close contact with sick people.
COVID-19 also spreads through droplets . The transmission distance is very limited so a person must be less than 2 meters from the patient to be infected. This is why you can prevent COVID-19 in the same way you can prevent the flu, cold, and other diseases that are transmitted by similar transmission.
Meanwhile, the use of masks is recommended for people who are sick so they are at risk of infecting others. If your body is healthy enough, you can protect yourself by washing your hands regularly and limiting contact with sources of infection.
