Flu

Although it can be anywhere between one and four days, the incubation period for influenza is typically two days.

Despite the fact that many people mistake influenza for a simple cold, it is actually a unique and deadly respiratory virus that can cause hospitalization and even death. Seasonal influenza infection rates are higher among young people. Adults 65 years of age and older, children under the age of 5, pregnant women, and persons of any age who have medical problems that put them at a higher risk for complications from influenza are at the highest risk for influenza-related complications, hospitalizations, and deaths.

Viral and bacterial pneumonia are the most common side effects of the flu. Inflammation of the heart (myocarditis), brain (encephalitis), or muscle is another consequence (myositis). The illness can also worsen chronic medical issues such cardiovascular disease, asthma and diabetes, causes heart attacks and congestive heart failure.
