Take steps to prevent respiratory illness

Prevention Graphic

Influenza (Flu)

Influenza (flu) is a contagious respiratory illness caused by viruses that infect the nose, throat, and lungs. Flu vaccines decrease the severity of flu-related illness, reducing the need for medical care and hospitalization. Symptoms of the flu include sudden onset of high fever, cough, sore throat, runny nose, headache, nausea, and fatigue.

  • A yearly flu vaccine is recommended for everyone ages 6 months and older. It's best to get your family immunized by October.
  • For those who are at higher risk of developing severe disease, vaccination is especially important. These groups include:
    • Older adults
    • Adults with certain chronic health conditions, such as asthma, heart disease, diabetes, and chronic kidney disease
    • Pregnant people
    • Children younger than 5 years, and especially those younger than 2 years old

Respiratory Syncytial Virus (RSV)

Respiratory syncytial virus (RSV) is a common respiratory virus that typically causes mild cold-like illness. Most people recover in a week or two, but infection can be serious for infants and older adults. 

  • Infants and young children: Monoclonal antibody treatments are CDC-approved and will soon be available to protect infants and young children from severe RSV. Parents can discuss this treatment option with their pediatrician.
  • Older adults: Vaccines are currently available for adults 60 years and older to protect against severe disease.
  • Pregnant people: This fall, pregnant people will be able to receive an immunization to protect themselves and their newborn(s) against severe respiratory illness and hospitalization.


Many people with COVID-19 have mild illness, but some people can become severely ill. Symptoms may include headache, fatigue, muscle aches, runny nose, fever, loss of sense of taste and smell, and fatigue. Convenient at-home tests can help determine if you have COVID-19. Updated 2023-2024 vaccines will soon be available.

  • COVID-19 vaccination is recommended for everyone ages 6 months and older. Vaccination is especially important for individuals at greater risk for severe disease including older adults and people with weakened immune systems. Vaccination decreases disease severity and helps prevent Long COVID, which can last for an extended duration following infection.

When to seek medical attention

If you have mild symptoms and are not at high risk for severe illness, care for yourself or family member at home, taking the following steps:

  • Get plenty of rest
