Airborne diseases
You can catch some diseases simply by breathing. These are called airborne diseases.
Airborne disease can spread when an infected person coughs, sneezes, or talks, spewing nasal and throat secretions into the air. Certain viruses or bacteria take flight and hang in the air or land on other people or surfaces.
When you breathe airborne pathogenic organisms in, they take up residence inside you. You can also pick up germs when you touch an infected surface, and then touch your own eyes, nose, or mouth.
Because these diseases travel in the air, they’re hard to control.
Types of airborne diseases
Many diseases are spread through the air, including these:
The common cold
Millions of cases of the common cold occur each year in the United States. Most adults get two or three colds a year. Children tend to get them more frequently. The common cold is the top reason for absences at school and work. There are many viruses that can cause a cold, but it’s usually a rhinovirus.
Influenza
Most of us have some experience with the flu. It spreads so easily because it’s contagious about a day before you notice the first symptoms. It remains contagious for another five to seven days. If you have a weakened immune system for any reason, you can spread it to others for longer than that.
There are many strains of the flu, and they are constantly changing. That makes it difficult for your body to develop immunities.
Chickenpox
Chickenpox is caused by the varicella-zoster virus. If you have chickenpox, you can spread it for a day or two before you get the telltale rash. It takes up to 21 days after exposure for the disease to develop. What you can do to prevent spreading an airborne disease
Although it’s impossible to completely avoid airborne pathogens, there are some things you can do to lower your chances of getting sick:
- Avoid close contact with people who have active symptoms of disease.
- [B]Stay home when you're sick. Don't let vulnerable people come in close contact with you.[/B]
- [B]If you must be around others, wear a face mask to prevent spreading or breathing in germs.[/B]
- Cover your mouth when you cough or sneeze. Use a tissue or your elbow to cut down on the possibility of transmitting germs on your hands.
- Wash your hands thoroughly (at least 20 seconds) and often, especially after sneezing or coughing.
- Avoid touching your face or other people with unwashed hands.
