Adenovirus is a type of virus that belongs to the family of Adenoviridae. It is a non-enveloped, double-stranded DNA virus. It can cause a wide range of illnesses, including upper respiratory infections, conjunctivitis (pink eye), gastrointestinal illness, and rarely, more serious illnesses such as pneumonia and bronchitis. It can also cause urinary tract infections, meningitis, and other illnesses.
Adenovirus is not a bacterial infection, but a viral infection. It is spread through contact with an infected person, through contact with contaminated objects such as toys, or through contact with contaminated water. It is highly contagious and can affect both adults and children. Symptoms may include a sore throat, fever, coughing, and headache. More serious symptoms can include pneumonia, bronchitis, and even death in some cases.
Treatment for adenovirus infections can vary depending on the type of illness and the patient's age. Generally, supportive care is the mainstay of therapy, which includes rest, fluids, and over-the-counter medications such as antihistamines. Severe cases may require hospitalization and antiviral medications. Vaccines are available to help prevent some types of adenovirus infections, but not all.
In summary, adenovirus is a type of virus that can cause a variety of illnesses, ranging from mild upper respiratory infections to more serious illnesses. It is a viral infection, not a bacterial infection, and is highly contagious. Treatment varies depending on the type and severity of the illness, but generally supportive care is the mainstay of treatment. Vaccines are available to help prevent some adenovirus infections.
