As heavy rains continue to lash parts of south China, people's safety and health are at risk. How can we prevent the outbreak of epidemics after flood disasters? Lin Jinlan, a specialist from the Office of Infection Control and Disease Prevention, Beijing Tsinghua Changgung Hospital, gave some suggestions for clean-up and recovery.

First, do not return home until the authorities have declared it safe, and follow their instructions. Garbage in and around homes should be removed in a timely manner.

Second, maintain good hygiene during flood clean-up by minimizing contact with floodwaters or anything that may have been polluted. Wear protective clothing, including rubber boots and gloves, safety glasses, a hard hat, and a dust mask.

Third, do not use tap water if you notice a change in its color, taste, or odor; throw away any food that has been in contact with floodwater, which is a breeding ground for bacteria and mold; and throw away soft plastic and porous items that have likely absorbed whatever the floodwaters brought in.

Fourth, heavy rains and increased humidity often cause pest activities. Large numbers of mosquitos, flies, fleas, ticks, and rats come out and multiply. Mosquito repellents and insecticides should be used to prevent contagious diseases, but be sure to keep them in a safe place out of reach of children and use them according to the instructions since most insecticides are poisonous.

Fifth, gas appliances and pipes may break during floods, causing a gas leak. If you suspect a leak or smell of gas, leave your home immediately and call the gas company. If you have any gas appliances that have been flooded, you need to clean the sludge out of the pilot and burners. But first turn off the gas.

Lin also warned that the elderly, children and people with chronic diseases are more susceptible to infectious diseases after flooding. Family members and relief workers should focus on providing them with as much protection as possible.
