Author:Look at the think tank Time:2022.07.12
On the evening of July 10, the media reported that a cholera case was suspected of having a suspected case of the Ministry of Engineering of Wuhan University.
On the morning of July 11th, the WeChat public account of "Dacheng Wuchang" posted news. Wuchang District Health and Health Bureau reported that on the evening of July 9, Wuchang District Disease Control Center received a report from the hospital that there was a case of infectious diarrhea in Wuhan University, which was based on vomiting and diarrhea. Lord, accompanied by low heat, serotics condensate test is O139 positive. After reviewing the provincial and municipal third -level disease control centers, the serum science condensation test of this case is O139 positive, diagnosed with cholera, and the toxic gene is negative.
Patients have been effectively diagnosed and treated, their condition has been controlled, and symptoms have disappeared. Our bureau has organized professional institutions for sampling detection and tracking management of relevant personnel, and temporarily closed control management and disinfection disposal of related places. No new cases are found.
The news of cholera cases in Wuhan University has attracted great attention on the Internet.
Hooois is an acute intestinal infectious disease, a legal category A infectious disease in my country, and one of the quarantine infectious diseases stipulated in the "National Health and Quarantine Law". The "People's Republic of China Infectious Disease Prevention and Control Law" stipulates that infectious diseases are divided into three categories: Class A, C, and C, a total of 39 types. There are only two types of infectious diseases, which are plague and cholera.
After the news of the choice of the University of Wuhan University, the screening method of the anal swab also attracted the attention of netizens.
A clinician of the infection department introduced that generally not diarrhea infectious diseases need to be used to obtain the sample for virus tests. If it is a patient with diarrhea, it can be tested with feces.
Our new crown screening has also been used in the new crown screening. The purpose is to detect whether there is a new coronal virus in the suspected infected digestive tract.
The anal swab sounds like a very uncomfortable detection method. The detection of digestive tract infectious diseases is very effective. When you have to use it, you have to grit your teeth.

Wuhan University has not yet released the summer vacation, and the school has strengthened management
The news of cholera cases in Wuhan University was circulated on the Internet yesterday. Xiao Li (a pseudonym), a student who is studying a graduate student of a liberal arts at Wuhan University, said that there is a dormitory of the Ministry of Engineering that appears in cholera cases. There is a distance of 3 kilometers. Therefore, his life has not been affected at present, nor does he do anal swab screening.
The student said that the counselor pulled the WeChat group last night, and there were more than a hundred students in the group. The counselor reposted the "Warm Tips on Strengthening the Prevention of Summer Infement infectious Diseases" released by the "Graduate Graduate of the Wuhan University".
According to the students of Wuhan University, according to the school calendar, Wuhan University has not officially released the summer vacation, so there are still a lot of students in the school, but at present, everyone's life and study are basically normal.
In recent decades, the cholera epidemic has occurred in China. Generally, the scale is not large, and it rarely causes death. In 2010, dozens of residents in Mengcheng, Anhui were infected with cholera, and belonged to a large -scale epidemic.
Every year, about 3 million to 5 million people in the world are infected with cholera, and the number of deaths reaches 100,000 to 120,000, mainly in countries with relatively low economic levels.

Anal swab detection, not as scary as you think
Students from the Ministry of Engineering of Wuhan University performed anal swab detection yesterday. Why do you do anal swab? Is this detection terrible?
Let's take a look at how the cholera is contagious.
The pathogens of the cholera are cholera. Patients with cholera and bacteria are infected. There are no symptoms or symptoms in patients with bacteria and mild patients, but there are germs in their excrement, so it is easier to infect the bacteria to the next person.
Under normal circumstances, the gastric acid in human gastric juice can eliminate the cholera in the food, and they can only survive for 4 minutes in normal gastric acid. But when gastric acid decreases or consumes a large amount of cholera, it can enter the intestine through the stomach.
The environment in the intestine is conducive to the reproduction of cholera, producing cholera bowls and leading to the occurrence of disease. Patients have spitting up and diarrhea, and the diarrhea is "rice -like water" and contains a large amount of pylori, which is a typical feature of the disease of cholera.
Summer is the peak season for cholera. When the disease is the worst, the patient's water loss can be as high as 1 liter per hour. Due to the loss of large amounts of water and electrolytes, water loss, metabolic acid poisoning, low alkaline and low -volume shocks and inconsistency and kidney failure. After treatment, patients can die within 12 to 24 hours, and the mortality rate is as high as 25%to 60%.
Vibrio Vibrius is mainly caused by contaminated water and food. Secondly, close contact with flies medium and life can also lead to spread. Regardless of race, age, and gender, crowds are generally prone to infection of cholera.
The cholera will not spread through the air, nor can it be spread directly through the skin. It is mainly transmitted through the septic channel. In short, the disease is from the mouth. However, if the skin is contaminated to cholera, not paying attention to hygiene and not paying attention to washing, it may also cause infection.
Huroish bacteria breed in the digestive tract, so you need to detect whether there are germs in the digestive tract. If there are diarrhea symptoms, you can detect it from the feces; if there is no diarrhea symptoms, the accuracy of detection through the anal swab is relatively high. Therefore, if it is a suspected cholera infection, it is a better diagnostic method to make anal swab, and it may be a bit uncomfortable, but you still need to bite your teeth to bear it.
Anal dove detection was also used in the new crown epidemic.
On January 20, 2021, an epidemic prevention and control conference in Beijing announced that at the time, a 9 -year -old boy was added to Daxing District, Beijing Daxing District. Nasopharyngeal swabs, oral pharmaceutical swabs, anal swabs and serum detection. The purpose of increasing anal swab detection is to reduce the diagnosis, because the new coronal virus can infect the digestive system in addition to the respiratory system, and some patients even have only the symptoms of the digestive system.
However, the anal swab screening in the new crown epidemic is not used on a large scale, but only the necessary suspected infected people or infected people who are necessary.
On June 28, the "Notice on Printing and Distributing New Coronatte Virus Pneumonia Prevention and Control Plan (Ninth Edition)" was released. Collect respiratory tract specimens (upper respiratory specimens or lower respiratory samples), and severe cases are prioritized to collect the lower respiratory tract specimens; specimens, whole blood specimen, serum specimen and urine specimen according to clinical needs. Items and environmental specimens are collected according to monitoring needs. For those who are not convenient to retain the stool, the anus swab can be collected.
This guide describes the acquisition of the anus swab: Gently insert the anus with a disinfection cotton swab 3 to 5cm, then gently rotate and pull out, and immediately put the 15ml external spiral cover of the 15ml of the 3 to 5ml virus preservation liquid In the middle, abandon the tail and tighten the tube cover.
After getting sick, there is no too "comfortable" service, so everyone still pays attention to personal hygiene, and the best health is healthy.
