Adenovirus infection is caused by the adenovirus, a type of virus that is found in many species of animals. The most common adenoviruses that infect humans are those that cause respiratory illness, including the common cold, bronchitis, and pneumonia. Other more serious diseases, such as conjunctivitis, gastroenteritis, and cystitis, can also be caused by adenoviruses. In rare cases, adenoviruses can cause more serious illnesses, such as meningitis and even death.
Adenoviruses are highly contagious and can be spread from person to person through contact with contaminated surfaces or through the air. They are also spread through contact with infected secretions, such as saliva, mucus, and feces. In addition, adenoviruses can be passed from mother to baby during childbirth.
Adenovirus infections typically cause mild symptoms, such as sore throat, fever, and cough. In more severe cases, adenovirus infection can cause pneumonia, eye infections, and gastrointestinal illness. Treatment typically involves rest, fluids, and medications to reduce fever and other symptoms. In some cases, antiviral medications may be prescribed to help reduce the severity of the infection.
Adenovirus infections can be prevented by practicing good hygiene, such as hand-washing and avoiding contact with people who are sick. Vaccines are also available for certain types of adenoviruses. Vaccination is especially important for people who are at risk of severe adenovirus infections, such as infants, young children, and people with weakened immune systems.
