但是，不是每位感染者都会出现上述症状哦
Hepatitis A is closely related to insufficient safe water, poor sanitation and poor personal hygiene habits. It spreads mainly through:
◎ Food-borne: Consumption of aquatic products (oysters, raccoons, clams, crabs, etc.), vegetables, and fruits contaminated with hepatitis A virus; prepare cold dishes and lettuce by hand with patients with hepatitis A or recessive infection; wash with water containing hepatitis A virus Raw food dishes can cause hepatitis A transmission.
◎ Water-borne: In places with poor management of faeces and water sources, especially after the rainstorm of the rainy season, faeces overflow the septic tank to pollute the water source, which may cause hepatitis A transmission.
◎ Transmission through daily life: In places with poor sanitary conditions and crowded living, patients can be directly or indirectly transmitted through hands, utensils, tableware, toys, clothes, etc. contaminated by feces.
◎ Other ways: Flies and cockroaches mechanically carry food contaminated with hepatitis A virus, which can also cause transmission of hepatitis A.
Therefore, it is important to close the "entry", ensure water or food hygiene, and do personal protection.
l Wash your hands before and after meals;
l Do not eat undercooked food;
l Do not drink raw water;

l Drug treatment
At present, there is no obvious difference in the efficacy of Chinese and Western medicines for the treatment of acute hepatitis A. Depending on the source of the medicine, local and western medicines should be selected for appropriate local or western medicine for treatment. There should not be too many types of medication, and the time should not be too long. The medication should be simplified. Routine use of corticosteroids for acute hepatitis is not recommended.
