When the floods hit the South, the China Meteorological Administration also issued seven high-temperature orange warnings on July 5, and two high-temperature blue warnings. In the summer, temperatures and humidity have increased significantly, and various types of infectious diseases have begun to “make a comedy†and prevent the development of diseases.
Zhang Jing, a researcher at the National Defense Center of the Chinese Center for Disease Control and Prevention, pointed out that common infectious diseases in the summer are intestinal infectious diseases and mosquito-borne infectious diseases such as diarrhea, food poisoning, acute gastroenteritis, Japanese encephalitis, dengue fever, and malaria. However, there may be yellow fever and Zika virus infection.
The reason why the summer is prone to cause disease transmission is because the high temperature and high humidity climate is conducive to the breeding of germs. On the other hand, because summer people are greedy and cool, it is easy to eat some cold food, resulting in decreased resistance of the gastrointestinal tract. They often blow air conditioners. Sleeping in air-conditioned rooms will also reduce people's resistance, which makes it easy for the bacteria to invade the body.
Be alert to children being infected with EV71 virus causing hand, foot and mouth disease
EV71 virus is a kind of human enterovirus, and it is one of the important pathogens causing hand-foot-and-mouth disease in infants and young children. In China, an outbreak of hand-foot-mouth disease caused by the EV71 virus occurred in Fuyang, Anhui in 2008, resulting in the death of 23 sick children. After 2008, a large-scale epidemic occurred in the country. Cases occurred in 31 provinces and a small number of children died severely. Zhang Jing reminded parents: “When the child has HFMD, there are four typical symptoms of high fever, vomiting, mental retardation, and tetany that persist for more than 3 days. These symptoms often indicate severe illness. Treatment and treatment of hospitals."
According to Yuechen Chen, Assistant Researcher at the National Immunization Planning Center of the China CDC, “The EV71 inactivated vaccine of our country was approved for marketing in December 2015. This vaccine is mainly used to prevent hand-foot-and-mouth disease caused by EV71 infection. 2016 5 In July, the Chinese Center for Disease Control and Prevention also issued a technical guide for the use of the inactivated vaccine for enterovirus EV71. It is recommended that children be vaccinated for children aged 6 months or more. In order to better play the protective role of the vaccine, the sooner the inoculation, the better. Shows that the EV71 vaccine is safe, has a good protective effect, and protects hand-foot-and-mouth disease caused by EV71 virus infection by more than 90%.â€
Of course, not all hand-foot-and-mouth disease is caused by the EV71 virus, and there are some relatively common "hand-foot-and-mouth" diseases. Zhang Jing said: "Children may also develop common infectious diarrhea, mainly due to eating unsanitary water and food. Especially in summer, children like to eat cold drinks, or we eat more cold dishes, or Improperly preserved meat foods are stored for a long time, causing the disease to multiply.Especially leftovers, people who eat without heating or cooking are very likely to cause diarrhea.Furthermore, the health of food processors is not doing well. Unhygienic diet may cause diarrhea in children."
For these basic preventive measures of intestinal diseases, Zhang Jing suggested: “The easiest thing is to wash your hands frequently, wash your hands before meals, and develop good hygiene habits. Then, give your children drinking water. Avoid crowding. Places, especially closed places, places where air is not very circulated (part of hand-foot-mouth disease can be transmitted by droplets).Educate children not to urinate or urinate anywhere, and regularly disinfect children’s tableware and utensils, especially bottles and toys. .
Mosquitoes after Zika virus
Summer is a season where mosquitoes are raging. Especially after imported Zika virus infection has occurred in China, although not all types of mosquitoes transmit Zika virus, we cannot neglect the prevention of mosquitoes.
Meng Fengxia, a researcher at the China Center for Disease Control and Prevention of Infectious Diseases Prevention and Control, said: "The summer family mosquito control is very important, and mosquitoes can transmit more diseases, such as dengue fever, malaria, and Japanese encephalitis. In the country, there are now some of the more interesting Zika virus disease that can cause neonatal microcephaly, yellow fever, Chikungunya fever, these are Aedes albopictus and Aedes aegypti In the spread, Culex tritaeniorhynchus is transmitted to Japanese encephalitis J. The prevention and control of mosquitoes requires everyone to pay attention to the fact that homes mainly have screen doors and screens, they can use mosquito nets, and household insecticides should also be prepared. First kill.Farming at home should pay attention to changing the water, the small water in front of the house should be promptly cleaned up, and the weeds around the family should be cleaned up in time.If there are too many mosquitoes, insecticides should be used. It is some measures to prevent mosquitoes, such as a person standing in a place and feeling that there are three or two mosquitoes to bite, this time around to find it, generally do not have ten meters to find mosquito breeding grounds. In places where water is, such as basins, it is OK to turn the basin upside down, if it is a small pool, sprinkle some insecticide or a handful of salt on it.If it is a pickle basin, cover a lid can also be, These little tricks are very easy to use."
In addition, the summer season coincides with the peak season of summer vacations, especially for those who go abroad. They must fight against the mosquitoes. Meng Fengxia pointed out: "Now many infectious diseases are imported from abroad. People who go out to travel and work outside, if they feel uncomfortable, once they come to China, they must first go to the hospital, do not go home, and do not visit. Friends, first come to the hospital to check, so that we can save many resources in our country, and we can also prevent relatives from being infected." (China Youth Network Liu Yirong)
