Hepatitis patients are contagious at the end of the incubation period, especially at the beginning of the disease when the contagion is strongest. If someone in the family shows weakness, fever, loss of appetite, abdominal congestion or fullness, it is important to seek medical examination for early detection, diagnosis, isolation and treatment. Hepatitis disease is best treated in isolation. Family members should promptly perform a thorough disinfection of the patient’s used items while the patient is hospitalized. If there is no condition for hospitalization, isolation treatment at home, should do “one alone”, “two protection”, “three apart”, “four disinfection “One alone Let the patient use utensils such as tableware, tea sets and toiletries alone. Two protection One should ensure regular disinfection, for example, dishes, cups and spoons should be disinfected at meals; indoor floors and toilets used by patients should be disinfected daily. Secondly, we should ensure the disinfection effect, such as the concentration of disinfectant solution should be sufficient, and the time of soaking and fumigation should be done strictly according to the requirements, not sloppy. Three separate, that is, live separately, eat separately, wash and put household items separately. Let patients live in a single room. The room should be kept free of flies, the door handle should be wrapped with gauze soaked with disinfectant solution, and disinfectant solution should be dripped frequently. If there is little room, the patient should sleep in a bed alone. Second, let the patient eat a single meal, do not mix with family members at a table to eat, and do not give the patient’s leftovers to others to eat. Third, the patient’s utensils and clothes should be disinfected and then washed and put in a single place to avoid cross-contamination. Four disinfection refers to four common methods of disinfection. 1, boiling disinfection pot steaming, boiling water to last half an hour after the water boils, in order to kill all types of hepatitis virus, this is the most simple and easy method in the family. This method is more suitable for the disinfection of eating utensils, nursing utensils, towels and bath towels, clothes, but this method cannot be used for plastic products, synthetic fibers and fur products. 2, liquid disinfection with 3% bleach clarified solution spraying the living room floor, white walls, closed doors and windows for 2 hours. For patient’s vomit, secretion and feces, disinfect with bleach and then flush or dump; for toilets, toilets and garbage, spray disinfection can be used; containers containing dirt can be soaked in 3% bleach clarification solution for 2 hours. Peroxyacetic acid disinfectant solution is suitable for disinfection of indoor surfaces, patient supplies, tableware, wooden furniture, plastic supplies, etc. Contaminated items can be soaked in 0.05% peroxyacetic acid solution for 2 hours; indoor disinfection can be achieved by spraying at a concentration of 0.75 to 1 gram peroxyacetic acid per square meter and confining for 30 minutes. Patients and their families should soak their hands in 0.2% peroxyacetic acid for 2 minutes before and after meals. The commercially available “disinfectant” is actually a chlorinated disinfectant and can be used according to the instructions. Some experiments have shown that the disinfection effect of Neosporin and chlorhexidine on hepatitis B virus is not yet certain, and that Dumefin, Lysol, rice vinegar, and balsamic vinegar have no effect on hepatitis B virus. 3. Sun disinfection of large items such as clothes and quilts can be exposed to the sun for 4-6 hours. 4, the fire patient’s waste can be burned by fire to eliminate future problems. There is no need to be nervous about having a hepatitis patient at home, as long as other members pay attention to isolation and disinfection, and develop good hygiene habits, you can avoid infection. People who are in close contact with hepatitis patients should have their liver function and hepatitis B surface antigen reviewed regularly to be on the alert for infection.
