Key Prevention Steps
We all have a role to play in limiting the spread of germs by practicing these key prevention measures:
- Stay up to date with vaccines. Vaccines are your best defense against severe illness. They can make your symptoms milder and shorter if you do get sick.
- Practice good hygiene, like washing your hands often with soap and warm water, covering your coughs and sneezes with your elbow or tissue, and cleaning commonly touched surfaces.
- Avoid contact with others if you or they are sick and consider staying home if you feel unwell to prevent spreading illness.
- Take steps for cleaner air. This can mean bringing in fresh outside air, purifying indoor air, or gathering outdoors.
- Know your treatment options. Treatments vary depending on the type of respiratory illness. Antibiotics help with bacterial infections. Antiviral medications may be prescribed for certain viral illnesses like flu and COVID.
Additional Prevention Steps
These are extra measures that can further reduce your risk of respiratory illness. They can provide an extra layer of protection and can be especially important in certain settings or when illnesses are increasing in your community.
- Consider wearing a mask if you or those around you are at higher risk of severe illness, or if you’ve been exposed to someone with respiratory symptoms.
- Practice physical distancing. At peak respiratory illness times, keeping distance from others, especially in crowded or poorly ventilated spaces, can reduce the risk of spreading germs.
- Get tested when appropriate. Testing can help identify certain illnesses and inform your next steps. Talk to your health care provider to decide if testing is needed.
Protecting People Most at Risk
Certain groups are more vulnerable to severe illness from respiratory illnesses, including older adults, young children, people who are pregnant, and people with weakened immune systems, underlying health conditions, or disabilities.
If you or someone you care for falls into one of these categories, it’s essential to take extra precautions. Learn about specific considerations for these groups of people by visiting the CDC’s resources.
Treatment and Care
For some respiratory infections, symptoms often improve within a week or two with rest, hydration, and over-the-counter remedies. However, if your symptoms worsen or you are at higher risk of severe illness, contact your health care provider right away.
Antibiotics are used to treat certain bacterial infections. It’s important to treat some bacterial respiratory illnesses with antibiotics early.
Antiviral medications are used to treat some viral infections. They work best when started within a few days after symptoms start.
Your health care provider can help determine the best course of action based on your symptoms and medical history.

Recognizing Respiratory Illness
Respiratory illnesses, caused by bacteria or viruses, typically impact the lungs and throat. They spread easily through coughing, sneezing, or close contact. These illnesses are common during colder months when people spend more time indoors. Other respiratory illnesses caused by environmental factors or family history—like asthma or COPD—do not spread from person to person.
Understanding the range of respiratory illnesses and how they spread helps you take the right steps to stay healthy. Prevention is key, whether it’s through vaccines, everyday prevention practices, or seeking timely medical care.
These viral illnesses are common during fall and winter and can lead to severe outcomes, particularly for older adults, young children, and those with chronic conditions. Vaccines are the best way to protect yourself and others. Antibiotics do not work against these viral illnesses but antiviral medications may help if taken within a few days of feeling sick.
This is a bacterial infection that is very contagious and causes severe coughing fits. It can be dangerous for infants and young children. The best way to prevent whooping cough is to get vaccinated with the DTaP or Tdap vaccine. Antibiotics are often needed to treat whooping cough.
This illness is caused by various bacteria, including those responsible for walking pneumonia (Mycoplasma pneumoniae). It can affect people of all ages, but especially young children. Antibiotic treatment may be required for serious infections, like pneumonia.
Rhinovirus, adenovirus, and other non-vaccine-preventable respiratory illnesses can also circulate year-round. These often cause milder symptoms like runny nose, cough, and sore throat but can still impact daily life.
