An upper respiratory infection (URI) is an infection that affects the nose, sinuses, throat, and upper airways. The common cold is the most frequent type of upper respiratory infection. Most URIs are caused by viruses, although some infections may be caused by bacteria.
Common upper respiratory infections include:
Most upper respiratory infections are mild and improve on their own within 7 to 14 days with rest, fluids, and symptom management. Because most URIs are caused by viruses, antibiotics are usually not needed unless a bacterial infection is suspected or confirmed.

Upper respiratory infections are among the most common illnesses affecting people of all ages. Adults typically experience two to four colds each year, while children may have six to eight or more because their immune systems are still developing.
URIs occur throughout the year but are most common during the fall and winter months when respiratory viruses spread more easily.
Common Cold – CDC

Provides information about the common cold, how it spreads, and prevention strategies.
Symptoms vary depending on the virus or bacteria causing the infection.
Common symptoms may include:
Most symptoms gradually improve over one to two weeks, although a cough may last longer.
Your healthcare provider will review your symptoms, recent exposures, and medical history, and perform a physical examination.
Most upper respiratory infections are diagnosed based on your symptoms alone. Additional testing may be recommended if influenza, COVID-19, RSV, strep throat, or another illness is suspected.

Most upper respiratory infections are caused by viruses that spread easily from person to person.
Common causes include:
Less commonly, bacterial infections may develop after a viral illness.

Most upper respiratory infections improve within 7–14 days, although a cough may last up to 3–8 weeks after the infection has resolved.
Most people recover completely without long-term problems. However, some individuals—especially older adults, infants, or those with chronic medical conditions—may develop complications such as sinus infections, ear infections, bronchitis, or pneumonia.
Follow up with your healthcare provider if symptoms persist or worsen.
Home care is one of the most important parts of recovering from an upper respiratory infection.

No. Most colds and upper respiratory infections are caused by viruses, so antibiotics do not help.
A cough often improves within
, although some coughs may continue for several weeks after the infection has resolved.
Light activity may be acceptable if your symptoms are mild and limited to above the neck (such as a runny nose or sore throat). If you have fever, chest congestion, shortness of breath, or significant fatigue, rest until you recover. If you are unsure, ask your healthcare provider.
In general, you should stay home until your fever has resolved without fever-reducing medication and you feel well enough to participate in normal activities. Follow your healthcare provider’s recommendations.
Many can be prevented by washing your hands frequently, avoiding close contact with sick individuals, staying current on recommended vaccinations, and maintaining healthy lifestyle habits.
Consider asking your healthcare provider:
Most upper respiratory infections are managed by a primary care provider. Depending on your symptoms or medical history, your provider may recommend seeing a specialist.

Most upper respiratory infections are temporary and resolve completely with rest, fluids, and supportive care.
Because most URIs are caused by viruses, they improve as your immune system clears the infection. Bacterial infections may require antibiotics. Most people recover fully without lasting complications.
