1. Drinking water hygiene.
Do not drink raw water, but only boiled water or bottled water and bottled water that meet the hygiene standards; Water containers must be clean and often emptied for cleaning; Well water, river water, lake water and pond water for temporary drinking must be disinfected; Water with high turbidity and serious pollution must be clarified with alum before disinfection; Disinfectants for drinking water (bleaching tablets, disinfectant effervescent tablets) must be stored in a dark, dry and cool place (such as screwing the cap of a brown bottle). If the tap water pipeline or faucet is polluted, the pipeline should be thoroughly cleaned after the water is drained, and the surface of the faucet should be wiped with chlorine-containing disinfectant and disinfected.
2. Food hygiene.
Food should be thoroughly cooked, raw and cooked separately, tableware should be cleaned and disinfected before use, and hands should be washed before eating; Don't eat spoiled or flooded food; Do not eat drowned or dead livestock and aquatic products; Do not eat leftovers, do not eat cold food; Don't buy food at stalls without food business licenses.

Remove stagnant water, sludge and garbage; Open doors and windows, ventilate, clean furniture, clean indoor items, and disinfect room walls and floors when necessary; Renovating toilets, cleaning toilets, and repairing livestock pens. Don't urinate anywhere, and the feces, excrement and garbage should be discharged in designated areas.
4. Vector control.
Install screen doors, screens, mosquito nets and other anti-mosquito and fly facilities in the residence; It is suggested that household measures such as mosquito-repellent incense, aerosol cans and fly swatter should be used to kill mosquitoes and flies. The flood fighting personnel on duty should be equipped with mosquito-repellent caps and long-sleeved clothes, and mosquito repellent can be sprayed on exposed parts. Efficient and safe anticoagulant rodenticide should be used to kill rats; Search for dead rats in time after deratization, and bury or burn them centrally; When rats die or migrate in the flood, parasites on the body surface escape or escape, and rats are killed, pesticides should be sprayed at residents' resettlement sites to eliminate parasites such as free fleas that leave rats, and rats and insects should be killed together. The abnormal increase of mosquitoes, flies, rats and other vectors should be reported to the local government departments in time.
5. Wash by hand.
Don't rub your eyes with your hands, especially dirty hands. Everyone's towel and washbasin should be used separately. If the washbasin must be used with patients with acute hemorrhagic conjunctivitis (commonly known as pink eye), it should be used by healthy people first, and then used by patients. After use, wash the washbasin with soap and soak it with disinfectant.
How to disinfect after the flood is safe?
Wells should be drained and disinfected.
During the flood, the water source may be polluted by human and animal feces, garbage and corpses, which may easily lead to infectious diseases. In case of flood disaster, temporary water supply is usually needed, and bottled water can be purchased for emergency. Boiling water is a very effective method for sterilization and disease prevention, so drinking boiling water instead of raw water should be advocated in disaster areas. During the disaster, the main disinfection method of drinking water is to use disinfectant for disinfection. There are many kinds of disinfectants, such as bleach. Add disinfectant and leave it for a while before drinking.
If the well is flooded, it is not safe to drink it directly even after the flood recedes. Therefore, the well should be cleaned and disinfected after water intake. For flooded wells, drain the well water first, remove silt, wash the shaft wall and bottom of the well, and then discharge all the sewage. After the well naturally seeps to the normal water level, it is disinfected by over-metering chlorination. The dosage is calculated by adding 180 pieces of bleaching concentrated solution per ton of well water (dissolved and poured). After soaking for 12 hours, drain the well water, and after it naturally seeps to the normal water level, disinfect it according to the normal disinfection method (add 8- 10 pieces of bleaching concentrated solution to each ton of water), and then put it into normal use.
Do a good job of killing mosquitoes and flies
In order to prevent the outbreak of the epidemic, the Provincial Health Planning Commission asked the disaster-stricken areas to actively carry out activities such as eliminating mosquitoes, flies and rats. According to reports, many methods can be used to kill flies, such as drug spraying, bait trapping, sticky catching and so on. To kill flies, household hygienic insecticides approved by relevant state departments should be used, such as aerosol, spray, poison bait, etc.
To kill mosquitoes, we must first pay attention to environmental management, remove stagnant water and control its breeding grounds. In areas where mosquito-borne infectious diseases are prevalent, outdoor adults can be sprayed with dichlorvos, and indoor adults can stay with pyrethroids and spray or soak mosquito nets.
