How Does RSV Affect Different Age Range Groups?
Respiratory syncytial virus (RSV) is a common respiratory virus that in most people causes just symptoms or mild illness. Babies, children, and older adults are usually more sensitive to the virus and may become much sicker if they catch it.
Respiratory syncytial virus (RSV) is a common respiratory virus that causes mild illness in most people. However, for babies, young children, and older adults – or anyone else with a weakened immune system – this virus can cause more severe symptoms and serious illness.
RSV affects people of different age groups differently. Infants, young children, and people older than 60 are at greater risk of serious symptoms and hospitalization from RSV than teens and younger adults.
Here’s more information about how RSV affects different age ranges:
Infants and young children are one of the groups that may develop severe illness from RSV. According to the Centers for Disease Control and Prevention (CDC) , about 58,000 to 80,000 children under 5 years old with RSV are hospitalized, and 100 to 300 children younger than 5 die each year from RSV. RSV can lead to more severe illnesses such as pneumonia or bronchiolitis.
RSV symptoms in infants and young children
For infants and children, symptoms of RSV can be difficult to tell apart from symptoms of other viral respiratory illnesses.
Preventable medical errors kill about 22,000 patients a year, according to research from the Yale School of Medicine. That’s much less than a previously reported number of 250,000 deaths a year where medical error is to blame.
Early symptoms may include:
In severe cases of RSV, coughing can progress to wheezing and difficulty breathing.
In very young babies, symptoms can also include:
- irritability
- decreased activity or energy
- decreased appetite
- pauses in breathing that last 10 seconds or more (apnea)
Risk factors for RSV in infants and young children
Children under the age of 5 are at a higher risk of catching RSV than older children. Infants and younger children have immune systems that aren’t fully developed yet, but other reasons some children are at a higher risk from RSV include:
- prematurity
- chronic lung disease
- a weakened immune system
- neuromuscular disorders
- difficulty swallowing or coughing up mucus
Teenagers aren’t as likely to become seriously ill from RSV, although certain medical conditions or immune system conditions can increase anyone’s risk of becoming severely ill from RSV.
Symptoms in teens with RSV
Symptoms of RSV in teens include:
Risk factors for RSV in teens
Most teens and adults develop mild respiratory symptoms from RSV. Symptoms typically begin about 4 to 6 days after infection and may include:
Like teens, most adults can also have RSV without becoming severely ill. Adults with weakened immune systems or certain medical conditions may be at an increased risk.
Symptoms in adults with RSV
Symptoms in adults are similar to those in teens and may include:
Risk factors for RSV in adults
Risk factors in adults include being exposed to someone with RSV. Adults with weakened immune systems or other medical conditions may have more serious symptoms from RSV.
Adults ages 65 and older fall into the age range most seriously affected by RSV. More older adults are hospitalized or die from RSV than children.
According to the CDC , between 60,000 and 160,000 older adults are hospitalized with RSV each year, and between 6,000 and 10,000 die.
Symptoms in adults with RSV
Adults ages 65 and older are usually at a greater risk of getting RSV, but symptoms in this group are similar to the ones in younger adults. However, older adults are more likely to develop severe complications from RSV.
The virus can also worsen underlying conditions older adults may have such as chronic obstructive pulmonary disease (COPD), congestive heart failure, and asthma.
Risk factors for RSV in older adults
Adults older than 65 are also at an increased risk because of the fact that immunity decreases with age. However, adults of any age with a weakened immune system or heart or lung problems also have a higher risk of severe illness.
When to get emergency care
Whether you have RSV or another respiratory infection, get immediate medical care if you or your child develop difficulty breathing.
- shortness of breath
- a blue tinge to the lips or nail beds
- dizziness
- loss of consciousness
