Symptoms of viral asthma may include difficulty breathing, chest tightness, and wheezing. People may also have additional symptoms that are similar to those of the common cold.
Viral-induced asthma, or viral asthma, occurs when a virus triggers an asthma attack. The symptoms of viral asthma may be the same as typical asthma symptoms. They may also accompany symptoms of the common cold, such as a runny nose or sore throat.
In this article, we will look at the symptoms of viral asthma, what causes it, and how doctors treat it.
Asthma symptoms include:
- trouble breathing (shortness of breath)
- tightness or pain in the chest
- a wheezing or whistling sound, especially when exhaling
When someone has viral-induced asthma, they may have other symptoms, such as those of the common cold. It is important to contact a doctor for a diagnosis and treatment, especially for infants and children.
Respiratory syncytial virus (RSV) is the leading cause of bronchiolitis, a viral lung infection
The 2020 review adds that breathing difficulty induced by either of these viruses may have associations with the later development of asthma. Generally, RV is a risk factor for later atopic, or allergic, asthma. Experts more often associate RSV with later nonatopic asthma.
Evidence indicates that RV, the common cold virus, is the most common single trigger of viral exacerbations. It causes up to
Other viruses may also cause bronchiolitis, wheezing, and asthma, including:
Evidence suggests that although scientists have made progress in understanding viral asthma, they need to understand it more to help prevent it. However, a study suggests that oral corticosteroids can decrease wheezing in the 12 months after viral infection and decrease the incidence of asthma by
In some cases, viral asthma may also require emergency treatment or hospitalization.
The virus for the common cold can be a primary trigger for viral asthma. Because of this, it may make sense to utilize strategies to help prevent the common cold in people prone to asthma. The
- washing their hands often
- avoiding touching the eyes, nose, and mouth with unwashed hands
- staying away from people who are unwell, where possible
The American College of Allergy, Asthma, and Immunology advises that any asthma symptom can become serious and even life threatening if a person does not treat it. If adults or children have asthma symptoms, they should consider contacting a doctor or attending the emergency room if symptoms are severe.
Symptoms of viral asthma may be the same as any type of asthma. For instance, chest tightness, trouble breathing, and wheezing are common symptoms of viral-induced asthma. Additionally, someone may have symptoms relating to the virus that lead to asthma exacerbation.
Wheezing in infants may be a sign of bronchiolitis, and a doctor may need to differentiate this from asthma. However, infants who develop bronchiolitis may be more at risk of developing childhood asthma. Other asthma triggers in adults and children may include cigarette smoke, pet hair, or dust mites.
