There are 1 cholera cases in Wuhan University, will it be on a large scale in the future?

According to the current domestic health and medical conditions

Choi is unlikely to appear large -scale communication in China

Today, the rumors of "Wuhan University suspected to find a cholera case" finally settled.

The public account of the "Dacheng Wuchang" public account of Wuchang District, Wuchang District, Wuhan City, stated that after review by the provincial and cities, a case of infectious diarrhea occurred in Wuhan University, the serotics condensation test was O139 positive. Choib, toxic gene negative. Patients were mainly vomiting and diarrhea, accompanied by low heat, effective diagnosis and treatment, the condition has been controlled, and the symptoms have disappeared.

Public information shows that cholera is an acute intestinal infectious disease caused by the contaminated food or water intake. The epidemic time in China is March to November, the peak of the disease is in summer and autumn, and the peak of popularity from June to September. The cholera can cause diarrhea dehydration or even death within a few hours. Nowadays, there are about 1.3 million to 4 million cases every year in cholera every year, and 21,000 to 143,000 deaths.

"The source of this choice case in Wuhan is unclear. The specifics depends on the follow -up results of the follow -up traceability." Guo Wei, deputy chief physician of Tongji Hospital affiliated to Tongji Medical College of Huazhong University of Science and Technology, told China News Weekly. At present, I haven't seen this infected person infected with surrounding personnel. Unless the infected person is engaged in the catering industry, the probability of large -scale communication is relatively small. In the future, regular monitoring of the cholera epidemic should be strengthened, and personal health management and diet safety should be strengthened.

What may be the source of communication?

As one of the international quarantine infectious diseases stipulated in the International Health Regulations, the choice is also one of the "mandatory management" of "mandatory management" of the "Prevention and Control Law of the People's Republic of China". The popular strains of the O1 group and the O139 group of cholera have been recognized as the main pathogen of cholera. The most common cause of infection is the most common infection in the water. Hoothye can produce cholera toxins and cause secretion diarrhea.

"When the living standards and hygiene conditions were not so good in the early years, the mortality rate of the choice was about 50%. This also caused the cause of the Class A infectious disease before." Once in a comprehensive third -level A -level A class The hospital's infection department has worked for many years, and now Wang Suna, who has served as a doctor of Healthy infection, has been engaged in the research of infectious diseases all year round. She told "China News Weekly" that cholera bacteria include more than 200 gene subtypes. The diseases are called cholera. Only those who produce cholera toxins can cause typical cholera symptoms. Among these more than 200 gene subtypes, only O1 groups and O139 groups can produce cholera toxins.

On July 10, there was news on the Internet that on the evening of July 9, the dormitory of the Ministry of Engineering of Wuhan University was suspected of finding a cholera, and the students in the whole building conducted a unified anal swab test. Today, the Wuchang District Health and Health Bureau has organized professional institutions to conduct sampling, detection and tracking management of relevant personnel, and conduct temporary closed control management and disinfection disposal of relevant places. No new cases are found.

Wuhan is located in the eastern part of the Jianghan Plain. The middle reaches of the Yangtze River and the Yangtze River and Hanshui are located. In recent years, the number of cholera cases in Wuhan has been very scarce and emitted. The Wuhan Disease Prevention and Control Center has detected non -popular strains of O43 group cholera in 2010 and 2014. So why did the cholera epidemic appear in Wuhan this time? What is the source?

"At present, there are no more cholera distribution cases in Wuhan, or small -scale outbreaks." In Guo Wei's view, it is hard to say that the sudden cholera cases are related to the local situation in Wuhan, but now it seems More like an individual cases caused by occasional factors.

"If the flow traceability is clear, it is still expected to find the source of the communication." Guo Wei said, for example, the infected person has just been to areas with cholera cases some time ago, or have been exposed to overseas personnel. Adjust information.

Wang Suna told "China News Weekly" that if there are no new infections in the future, this case is not much different from the previous cases of exfoliating cases, and you don't have to panic. However, if there are only one infected person, it is difficult to trace the source of the infection, because the lack of clear communication chain.

"As of now, there are only one choice case in Wuhan. If there are no new cases in the future, there is no need to panic. The infection and communication of cholera have a lot to do with the environment and personal hygiene. Therefore, for most people, at present It is the most important thing for active prevention. "Guo Wei said that once symptoms such as diarrhea occur, you should go to the hospital's intestinal clinic in time. In addition, you should also pay attention to the safety of diet, avoid cold or cooked food, as well as unprecedented water. In your daily life, you should wash your hands frequently, avoid spreading agents such as flies, cockroaches such as flies, cockroaches in the living environment, and family hygiene.

Most of the domestic cases are distributed, it is difficult to pass on people

Chilen often spreads through food and water. Due to the short incubation period and urgent onset, in areas lacking food and drinking water safety guarantee, a characteristic of the choice epidemic is suddenly outbreak, spreading rapidly, which can lead to large -scale popularity across regions, or even even Causes global popularity. According to literature, in the past three decades, the number of cholera cases reported to the World Health Organization every year mostly between 100,000 and 600,000 cases, up to more than 1.2 million cases, and the mortality rate is between 0.2%and 4.5%. It is mainly concentrated in the backward economic level of Asia, America, and Africa, and countries and regions that have suffered serious natural disasters and humanitarian crises. As of now, seven cholera worlds have occurred around the world, and it is still in the seventh popularity worldwide. "As a kind of intestinal infectious disease, cholera cannot be completely removed. On the one hand, overseas input risks from poor sanitary conditions such as Africa and India continue to exist; on the other hand When you are waiting for the place, there is a risk of infection. "Guo Wei said.

In the 11 years from 1949 to 1960, cholera was almost extinct in China. After that, there were three cholera peaks in China, which occurred in the 1960s, 1980s, and 1990s, respectively. People are generally susceptible to cholera. Due to gastric acid and immune capacity, they are not infected with cholera. But no matter whether or not or not, people who infected the vycese vycene are the source of the disease.

For China, the temperature is high from July to October each year. It is the peak period of the onset. The coastal areas and the area near Haikou of the river are the main popular areas. However, due to the development of transportation, trade exchanges, and a large population flow, there are cholera inland areas.

In recent years, with the improvement of people's living standards, improvement of hygiene conditions, and improving health awareness, the probability of domestic cholera's large -scale outbreaks and popularity of popularity, and cholera cases are basically distributed. Except for a cholera epidemic in the southeast coastal areas in 2005, the number of cases in most years was tens to one or two hundred cases, and there were less than 20 cases of cholene annual reports in some years. Wang Suna said that in fact, there are cholera cases every year, just because the number of cases is rare and it has not been widely spread. These cases emitted in China are often water -based or food -based. For example, some people have eaten imported seafood products that are not cooked.

She analyzed that cholera can spread between people, but it mainly depends on how high the content of cholera in the infected person's body. If it is a patient with severe illnesses, the number of choleram in the 1-liter of this patient can reach 10 billion to 10 billion, so that after using the bathroom and sink of the toilet, the second person will contact this. The environment, if you do not wash your hands, you may be infected with cholera. "Now everyone pays more attention to personal hygiene, wash hands before meals, and does not have the situation of pollution water sources, so it is difficult to appear in the large -scale spread of the cholera crowd."

"Not everyone's infection of cholera is severe, the severity is related to their own health status and their own degree of strength." Wang Suna added that the treatment of cholera is relatively mature. Generally Proper use of antibacterial drugs. If you go to the hospital in time after the infection is found, basically 99%of people can be cured, and the mortality rate is very low. Conversely, if you do not seek medical treatment in time, continuous diarrhea will cause severe dehydration and electrolyte disorders in the body, so the risk of death is relatively high.

It is worth noting that there are oral two -price vaccines for cholera in China, mainly for the O1 group and O139 groups of cholera. "Because there are too few domestic cases, few people usually take vaccination, and there is no need to vaccinate. For those who go to the high incidence of cholera epidemic such as Africa, the cholera vaccine in advance will not lose a good way to prevent it." Guo Wei said.
