Adenoviruses are common viruses that can cause a variety of issues such as cold-like symptoms, bronchitis, sore throat, diarrhea, pneumonia, conjunctivitis, and more.
An adenovirus infection can affect individuals of all ages. However, those who have weakened immune systems, or existing cardiac or respiratory disease, are more likely to have a more severe form of the disease. The adenovirus is an extremely hardy virus that can survive long durations outside a host. There are 52 serotypes of adenovirus and it has therefore been recognized as the etiologic agent of various syndromes.
Transmitted via direct inoculation (i.e. to the eye) , fecal-oral route, bodily fluids (i.e. blood) , and aerosolized droplets, the virus can affect various organ systems. Adenovirus is commonly isolated in both infants and children. In immunocompetent hosts, severe morbidity and mortality are rare.
Symptom #1: Fever
Fever or pyrexia occurs when the set point of body temperature in the central nervous system is abnormally elevated. The increase results in a feeling of coldness and more muscle contractions in an effort to generate and conserve heat. A fever can be caused by various conditions, including infections (viral, bacterial, parasitic, fungal). Different manifestations of adenovirus infection can cause a fever. Some of these syndromes are acute respiratory disease (ARD), pharyngoconjunctival fever, acute hemorrhagic nephritis, and gastroenteritis.
The treatment of fever is generally unnecessary. However, once the cause of the fever has been established by a physician, certain medications can be prescribed to lower body temperature and improve other associated symptoms.
