Adenovirus is a type of virus that can cause a number of respiratory illnesses, including bronchitis and pneumonia, in children. Adenovirus can last anywhere from a few days to several weeks, depending on the individual case.
In general, symptoms of adenovirus such as fever, sore throat, and runny nose usually resolve after about a week. However, the virus can remain in the body for several weeks, even after symptoms have disappeared. This means that the virus can continue to be spread during this time even if the child does not appear to be sick anymore.
In terms of treatment, antibiotics are not effective against adenovirus, since it is a virus. Instead, supportive care is recommended to help the child cope with the symptoms, such as rest, fluids, and pain relievers. In some cases, antiviral medications may be prescribed, although the effectiveness of these medications is still uncertain.
Adenovirus can also be spread through contact with an infected person or through contact with contaminated surfaces. It is important to practice frequent hand washing and to clean and disinfect surfaces that may be contaminated with the virus, such as door handles and toys.
In conclusion, adenovirus can last anywhere from a few days to several weeks in children, depending on the individual case. Although there is no specific treatment for the virus, supportive care such as rest, fluids, and pain relievers can help the child cope with the symptoms. Additionally, it is important to practice good hygiene to help prevent the spread of the virus.
