explain three airborne disease
Answers
Explanation:
An airborne transmission is disease transmission through small particulates that can be transmitted through the air over time and distance.[2] Diseases capable of airborne transmission include many of considerable importance both in human and veterinary medicine. The relevant pathogens may be viruses, bacteria, or fungi, and they may be spread through breathing, talking, coughing, sneezing, raising of dust, spraying of liquids, toilet flushing or any activities which generate aerosol particles or droplets. Human airborne diseases do not include conditions caused by air pollution such as volatile organic compounds (VOCs), gases and any airborne particles.
Airborne transmission is distinct from transmission by respiratory droplets. Respiratory droplets are large enough to fall to the ground rapidly after being produced (usually greater than 5 μm), as opposed to the smaller particles that carry airborne pathogens. Also, while respiratory droplets consist mostly of water, airborne particles are relatively dry, which damages many pathogens so that their ability to transmit infection is lessened or eliminated. Thus the number of pathogens that can be transmitted through an airborne route is limited.
Answer:
The common cold
MillionsTrusted Source 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 5 to 7 days. If you have a weakened immune system for any reason, you can spread it to others 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.
Most people get chickenpox only once, and then the virus goes dormant. Should the virus reactivate later in life, you get a painful skin condition called shingles.
If you haven’t had chickenpox, you can contract it from someone with shingles.
