What Is Rhinovirus?
The common cold is caused by a virus. More than 200 different viruses are known to cause the common cold. One such type of virus is the rhinovirus.
Rhinoviruses (from the Greek word rhin, meaning "nose") are the cause of the common cold in an estimated 30 to 35 percent of all adults. More than 110 distinct rhinovirus types have been identified. This virus belongs to the Picornaviridae family of viruses. A rhinovirus is a very small RNA virus.
Rhinovirus types are most active in early fall, spring, and summer. They can live up to 3 hours on your skin. They also can survive up to 3 hours on objects such as telephones and doorknobs.
These viruses grow best at temperatures of about 91 degrees Fahrenheit, the temperature inside the human nose.

Common colds are most frequent from September to April in temperate climates. Rhinovirus infections, which are present throughout the year, account for the initial increase in cold incidence during the fall and a second incidence peak at the end of the spring season. Colds that occur from October through March are caused by the successive appearance of numerous viruses, including coronavirus, RSV, and influenza virus, and parainfluenza. Adenoviral infections occur at a constant rate throughout the season.Age
Because antibodies to viral serotypes develop over time, the highest incidence is found in infants and young children. In addition, young children are more likely to have the frequent, close, personal contact necessary to transmit rhinovirus. Contrary to the experience of adults, children may also be more contagious due to having higher virus concentrations in secretions and longer duration of viral shedding.When someone becomes infected with a rhinovirus, he or she will experience what is commonly known as the common cold. The symptoms usually begin 2 to 3 days after infection. The symptoms of infection with this type of virus often include:
- Mucus buildup in your nose (Nose dryness or irritation is often the first symptom and is followed within hours by profuse watery rhinorrhea, nasal secretions typically become thicker and colored after the first few days of illness; nasal congestion, and sneezing.)
- Fever is absent or low grade. Infants and preschoolers are more likely to experience fevers, which are often 100-102oF
- Nasal obstruction can interfere with sleep and feeding
- Swelling of your sinuses
- Sore throat
- Cough
- Headache
An infection rarely causes serious problems.
How Is It Transmitted?
Transmission of the rhinovirus occurs in one of two ways:
- Touching your skin or environmental surfaces, such as telephones and stair rails, that have the rhinovirus on them and then touching your eyes or nose
- Inhaling drops of mucus full of rhinovirus from the air when a contagious person coughs or sneezes.
Just like with any other common cold virus, there are no treatments that can kill a rhinovirus. Therefore, treatment involves relieving symptoms as the body fights the rhinovirus infection. Some ways to reduce symptoms caused by an infection include:
- Drinking plenty of fluids
- Resting in bed
- Taking common cold medicine
- Gargling with warm salt water or using throat sprays or lozenges
- Using a cool-mist humidifier.
There are several ways you can reduce your chances of getting a rhinovirus infection. Suggestions include:
- Washing your hands regularly
- Keeping your hands away from your nose, mouth, and eyes
- Limiting exposure to infected people
- Practicing healthy habits
- Using disinfectants.
