Who's Most at Risk for Rotavirus? Understanding the Danger Zones
Published: Apr 19, 2024
While anyone can catch rotavirus, certain groups are more likely to develop severe illness. Knowing who's at highest risk can help you take extra precautions to protect yourself and your loved ones.
Young Children: The Prime Target
Children under 5, especially those between 6 months and 2 years old, are at highest risk for severe rotavirus. Their developing immune systems haven't built up defenses against the virus yet. In countries without widespread vaccination, nearly every child will have had rotavirus at least once by age 5.
Weakened Immune Systems
People with compromised immune systems face greater danger from rotavirus. This includes those with HIV/AIDS, cancer patients undergoing chemotherapy, and organ transplant recipients. For these individuals, rotavirus can cause prolonged illness and more severe symptoms, sometimes requiring hospitalization.
Older Adults in Group Settings
While rotavirus is often thought of as a childhood illness, outbreaks can occur in nursing homes and other long-term care facilities. Older adults may have weakened immune systems and be more vulnerable to dehydration. Close living quarters in these settings can also lead to rapid spread of the virus.
