HAdV infection can cause a variety of diseases, including pneumonia, bronchitis, cystitis, conjunctivitis, gastrointestinal diseases and encephalitis.
How does adenovirus spread?
The incubation period of human adenovirus infection is generally 2-21 days, with an average of 3-8 days. Symptomatic infected persons and asymptomatic latent infections are both sources of infection.
The transmission routes include:
Droplet transmission: is the main mode of transmission of adenovirus in respiratory tract infection;
Contact transmission: hands contact with objects contaminated with adenovirus Touching the mouth, nose, or eyes without washing your hands;

What are the symptoms of adenovirus infection?
Adenovirus is divided into mild infection and severe infection.
For children with normal immune function, adenovirus infection is usually self-limiting, and the disease is mild and can be cured by itself, and there are few sequelae.
Different types of adenoviruses have different effects. The more common mild symptoms are:
Fever, runny nose, cough, pharyngitis, etc., generally lasting 7 to 10 days;
Watery stools, diarrhea, and possibly vomiting, usually lasting 7 to 12 days;
Pharyngeal conjunctival fever: fever, sore throat, and symptoms of conjunctivitis (red eye) .
For these diseases, general symptomatic treatment measures can be taken: drink plenty of water, rest more, and relieve fever.

But for small babies around 6 months, newborns and even premature babies, or For children with immunodeficiency diseases, their immune systems are immature and do not have corresponding protective antibodies. Once infected, they are more likely to develop severe disease.
Children should be brought to a doctor to make sure there are no more serious infections:
<3 months of age and rectal temperature ≥ 38°C. Children should be brought to a doctor even if they appear normal or healthy;
3 to 36 months of age with a rectal temperature ≥ 38°C for more than 3 days. Seek immediate medical attention if child appears ill or unusually irritable, clings, or refuses to drink fluids;

recurrent fever, even if only for a few hours;
febrile with persistent illness , such as heart disease, cancer, lupus, or sickle cell anemia;
Fever with new rash.

Why are all swimming pools?
Li Tong, chief physician of the Department of Respiratory and Infectious Diseases of Beijing You’an Hospital, said that adenovirus infection is more common in swimming pools.
“It may be that the swimming pool contains adenovirus. If you touch the virus with your hands and then rub your eyes, touch your mouth and nose, you will be infected. It may also be because of the spread of respiratory droplets caused by the gathering of people in public swimming pools. The so-called’ Swimming pool fever’ (i.e. pharyngeal conjunctivitis) is caused by adenovirus and is mainly manifested in respiratory symptoms such as fever, sore throat, nasal congestion, and runny nose after swimming.”

Experts said that if the symptoms of adenovirus infection are mild, symptomatic treatment measures are generally enough, including drinking more water and resting. If you are suspected of being critically ill, you should seek medical attention as soon as possible.
Do a good job of personal protection, and the specific precautions include three aspects:
First, pay attention to hand hygiene, wash your hands with soap or hand sanitizer frequently, and do not rub your eyes with unclean hands, Touch your nose and mouth.
Second, try to avoid taking children to crowded places to avoid the risk of respiratory infection, and be sure to wash your hands in time after playing in public places such as shopping malls.
The third is to avoid gastrointestinal transmission. Do not touch the food directly before washing your hands. Parents must also wash their hands when preparing food for their children.
Currently
there is no vaccine related to adenovirus
and there is no specific medicine for it
so we can only pay attention to personal protection daily
Try to avoid “provoking” it!
