Henan Province hit by extremely heavy rainfall

The rainstorm will eventually pass, and after this disaster

Epidemic prevention work should arouse people's

Attach great importance

In cities, flooding can damage water pipes, sewers, and garbage disposal systems. Bacteria, viruses, protozoa, parasites, and other microorganisms and protozoa in them will spread with sewage. Some animals, such as rats, will move to higher places to avoid floods, increasing the chances of contact with humans.

In rural areas, if puddles, stagnant water, dead livestock, garbage, feces, etc. after floods are not handled promptly and effectively, mosquitoes are likely to breed, which will cause the spread of related infectious diseases. Therefore, self-protection and personal hygiene must be strengthened after the disaster.

Today we will study:

What should we pay attention to when drinking water after a disaster?

How to prevent post-disaster diseases?

What precautions should we take after heavy rain and floods?

Drinking water after disaster

After a flood, even if it is determined that the original water source has been treated with mature technology and the initial output state can be guaranteed to meet the drinking water standards, it will be affected by large-scale serious waterlogging in the urban area, and it is very likely to be re- contaminated by toxic and harmful chemical substances and biological pathogens during the water transportation, distribution and storage process.

If people in the disaster area follow their previous habits and use raw water to wash vegetables and fruits, and wash pots and dishes, it is very easy to cause food poisoning and water-borne diseases .

In rural areas, floods cause pesticides, fertilizers and other chemicals to be soaked, washed and dissolved by flood water, directly contaminating shallow water sources such as well water and stream water, and secondarily contaminating food.

Especially in the hot summer, microorganisms will multiply in large numbers in a very short period of time, which can easily cause intestinal infectious diseases such as typhoid/paratyphoid, bacillary dysentery, cholera, hepatitis A, hepatitis E, other infectious diarrhea and food poisoning .

It is particularly noteworthy that infectious diseases caused by flood-affected water and food often break out, aggravating secondary disasters. Therefore, everyone in the flood-affected areas must not take it lightly and must not drink raw water !

After the flood recedes, relevant departments should immediately assess the water source, and professionals should guide the cleaning and disinfection of water supply and storage pipelines. During this period, residents need to actively cooperate and disinfect their own tableware and utensils.

Post-disaster diseases

Floods will not only cause a certain degree of damage to residents' living facilities and environment, but also change living and sanitary conditions, making it easy for various infectious diseases to occur, especially intestinal infectious diseases, insect-borne and natural epidemic diseases, and infectious diseases through close contact.

1. Do not eat poultry and livestock that have been soaked in flood waters

After the flood disaster, because the market supply and transportation of food were affected, most people followed the principle of not wasting and saving, and dried the food that had been damp or even soaked by the flood before eating.

However, under the high temperature and high humidity conditions during the flood season, any food that has come into contact with flood water is extremely susceptible to contamination. The World Health Organization has also issued an urgent reminder: all food that has come into contact with flood water must be discarded!

In particular, livestock and poultry that have drowned or starved to death cannot be slaughtered and eaten cold; when fields are flooded, the various microorganisms in the soil will multiply , so unharvested and mature grains, potatoes, vegetables and fruits should also be discarded.

2. Do a good job in preventing flies, rats and mosquitoes, and prevent intestinal and insect-borne infectious diseases

Flies are the main source of infectious diseases such as hepatitis A, cholera, typhoid fever, and dysentery. Rats contain hemorrhagic fever virus, leptospira, and plague bacteria. Mosquitoes are the main source of infectious diseases such as Japanese encephalitis, malaria, dengue fever, filariasis, and yellow fever.

3. Wash your hands frequently and do not share personal items such as towels and handkerchiefs.

Hands are the organs of the human body that come into contact with the external environment the most. Infectious diseases can be easily spread by touching food, rubbing eyes, picking noses, etc. Infectious diseases transmitted through hands include intestinal infectious diseases such as hepatitis A, dysentery, cholera, typhoid fever, hand, foot and mouth disease, skin and mucous membrane diseases such as "pink eye", and respiratory infectious diseases such as influenza.

In addition, fever, vomiting, diarrhea and rash may be early signs of serious infectious diseases. Once they occur, seek medical attention as soon as possible to prevent an outbreak of the infectious disease .

Pay attention after heavy rain and floods

1. Prevent indoor mildew

In summer, the temperature is high and continuous heavy rains increase the air humidity to more than 80%. This, coupled with sufficient oxygen, provides an "excellent" soil for the growth and reproduction of mold. Active mold can cause furniture to mold and food to spoil. Its massively multiplied microscopic spores may also be inhaled by the human body, causing bronchitis, tonsillitis, asthma, etc.

In the bathroom and kitchen, water should be removed promptly after use, and water stains on the floor should be mopped up. Charcoal, bamboo charcoal or some granular dehumidifiers can be used in furniture and cabinets to help absorb moisture.

Keep kitchen bowls, chopping boards, towels, etc. dry. They can be disinfected in a special sterilizer or boiled in hot water . Once the weather clears up, all items should be exposed to the sun.

2. Prevent clothes from getting wet

Due to continuous heavy rain, clothes are difficult to dry and always feel damp, which not only affects the comfort of wearing, but in serious cases can also cause mold, which is harmful to human health.

Daily clothes can be dried in a dryer after washing, or when the clothes are almost dry, use a hair dryer or electric fan to help evaporate the remaining water from the clothes. Clothes soaked in rainwater should be washed again and dried according to the above method.

If clothes in the closet are found to be damp, they should be taken out and placed in a ventilated place to dry or dry in a tumble dryer.

3. Prevent dermatitis in the area soaked in rainwater

If heavy rain is not drained in time, it will cause water accumulation on the road. If your legs are soaked in the water for a long time, the soaked parts may turn white and swell, and in severe cases, it may also cause infection and ulcers .

If you have waded through water, wash the wet parts with clean water and soap and dry them immediately after returning home. Sprinkle talcum powder on the wrinkled parts such as between the toes to keep them clean and dry. It is recommended to wear rain boots when going out on rainy days. Change socks every day and brush shoes frequently.

No matter what the situation, if you experience symptoms such as itching and erythema on your feet, you should seek medical attention immediately . You can also keep some compound ointments containing antifungal ingredients at home.
