How Long Can an Adenovirus-Infected Individual Harbor It and When to Call Your Doctor?
The first few days after developing symptoms are the most contagious for adenovirus infections. Some patients, particularly those with compromised immune systems, might harbor the virus for weeks or longer in their tonsils, adenoids, or intestines. These individuals may not exhibit any symptoms, but they can still transmit the infection to others.
The majority of adenovirus infections will go away on their own rapidly. But it’s crucial to contact your doctor if you or your child exhibit any of the following signs:
- 104°F (40°C) or greater fever, or fever lasting more than five days.
- Breathing challenges.
- Dehydration.
- Decreased activity or alertness.
- Agitation or restless sleep.
