Navigating Respiratory Challenges: Understanding COVID-19, Flu, and RSV

什么是流感？

The flu is a contagious respiratory illness. It’s caused by influenza viruses that infect the nose, throat, and sometimes the lungs. It can lead to problems like ear infections or bacterial pneumonia. Sometimes it can lead to a hospital stay or even death. It can also make chronic conditions like asthma, diabetes, cancer, and others worse. Click 此处了解更多信息。

流感症状包括：

肌肉疼痛
疲劳
咳嗽
咽喉痛
头痛
Fever (not everyone with the flu gets a fever)
Some people also have vomiting and diarrhea. This is more common in children than adults.

什么是呼吸道合胞病毒 (RSV)？

RSV is also a contagious respiratory virus. It usually causes mild, cold-like symptoms, but it can sometimes be serious. Most people who get RSV will feel better in a week or two.

RSV is very common. Most children will get RSV by their second birthday.

RSV symptoms usually show up within four to six days of getting infected. RSV symptoms usually are:

流鼻涕
Lower appetite than usual
咳嗽
打喷嚏
发烧
喘息

Symptoms don’t usually appear all at once. Very young children with RSV may only have symptoms of:

易怒
Lower activity than usual
呼吸问题

Call your doctor if you or your child:

呼吸困难。
Cannot drink enough fluids.
Have symptoms that are getting worse.

Most RSV infections will go away on their own in a week or two. But some people are more likely to get very sick from RSV. This includes adults age 60 and older, pregnant people, and young children.

How can I protect myself and others from flu, a cold, COVID-19, or RSV?

Flu season begins in October and can last through May. You can get a cold any time of the year, but people are most likely to get colds from August to April. You can get COVID-19 any time of the year. RSV season begins in October and can last through April.

There are easy ways to protect yourself and others from these respiratory illnesses:

Wash your hands often. Use soap and water, and wash for at least 20 seconds.
Cover your mouth with your elbow, a tissue, or a shirtsleeve (not your hands) when you cough or sneeze.
Stay home if you feel sick.
Try to avoid direct contact with viruses. You can do this by avoiding kissing, shaking hands, and sharing cups or eating utensils.
Clean surfaces that are touched often, like doorknobs, cellphones, and light switches.

The best way to prevent the flu is to get a flu shot every year. Flu shots help reduce flu-related illnesses and the risk of serious complications.
