How does the adenovirus spread


What are adenoviruses?

Adenoviruses are non-enveloped viruses of the family Adenoviridae. They are highly contagious and spread around the world. Because of its environmental resistance, the virus is infectious for weeks at room temperature. It is only transmitted to humans and can cause a variety of diseases, including infections of the eyes, respiratory tract, or gastrointestinal tract.

How are adenoviruses transmitted?

Adenoviruses belong to the notifiable viruses in many countries, including Germany, provided they come from the conjunctival smear of the eye in order to determine the number of highly contagious eye infections. The virus is transmitted from person to person through direct contact and droplet infection, for example through the transmission of eye secretions. However, it can also be transmitted through indirect contact, for example via contaminated hands, contaminated instruments in doctor's offices and hospitals, or towels in communal washrooms. Follicular conjunctivitis and pharyngoconjunctival fever can also be transmitted through contaminated swimming pool water.

How does the disease manifest itself?

After an incubation period of 5 to 12 days, symptoms such as eye problems, respiratory diseases or gastrointestinal problems with nausea and diarrhea occur. More signs of a Adenovirus- Urinary tract infections, hepatitis and meningoencephalitis can also be infected. Infections of the eye, corneal inflammation or conjunctivitis are the most commonly transmitted. Affected people feel a foreign body sensation in the eye. The eye can itch, water and become sensitive to light. After 2 to 4 weeks, the eye inflammation usually subsides on its own and usually heals without any consequences. A patient is considered contagious until the virus can no longer be detected in excretions. After the first symptoms appear, this takes an average of 2 weeks.

Significance for infections in hospitals and in the outpatient sector

The meaning of Adenoviruses as a trigger of hospital outbreaks is secondary. As the cause of adeno-conjunctivitis, they are in the middle of the field in the statistics of notifiable diseases.

Survival time of the pathogen on inanimate surfaces

7 days to 3 months
