What Is Acute Bronchitis?
4. Causes
The most common cause of acute bronchitis is a type of virus. In the majority of cases, the virus responsible will be the same as those that are responsible for the flu and the common cold. This is one reason why acute bronchitis is often found after the patient has contracted another disease, like those mentioned.
These viruses are often transmitted in infected droplets when a person coughs or sneezes. They tend to be very contagious, making it difficult to completely protect yourself against them. Acute bronchitis will also sometimes be caused by environmental factors such as air pollution, fumes, vapor, and cigarette smoke.
