The flu is one of the most common infections in the United States, with over 7 million people hospitalized each year, and it’s an acute infection that can quickly cause serious side effects.

It can lead to a life-threatening respiratory infection called pneumonia, as well as other health problems.

Here are some of the common flu symptoms and ways to avoid them.

Flu symptoms: The first sign of flu symptoms is a mild cough, which can last for a few minutes.

However, this can change to a full-blown cough and then a fever.

The initial symptoms may include fever, a slight headache, a runny nose, and sometimes a slight rash.

If you have any of these symptoms, see your doctor immediately.

If it doesn’t feel better within 24 hours, call your doctor.

If your fever persists, call 911.

If symptoms worsen or you feel more unwell, call an emergency room (ED) or call your local health department (HCD).

Flu vaccines: You can get a flu vaccine for free from your doctor, but you’ll need to buy a second dose each year.

In most cases, you’ll get a booster shot for every 6 months you stay on the vaccine.

It’s also important to get a second shot if you’ve had any other flu-like symptoms in the past week.

If a second flu vaccine isn’t available, you may need to get the vaccine again.

The second shot can help protect against the other flu viruses, but it won’t make you immune to the new ones.

If the flu is mild, you should take the flu shot for two weeks.

After two weeks, it’s safe to go back to regular activities, but flu symptoms may increase again.

If flu symptoms are severe, or if you’re allergic to any of the flu viruses (such as whooping cough or seasonal flu), you may be prescribed a third shot of the vaccine for protection against the more common H5N1 influenza virus.

If both the H5 and H5n1 viruses are present in your body, you can get both flu vaccines.

If one flu vaccine doesn’t work, the other is still effective, but the chances of getting both flu shots are higher.
