What is cholera?
1
What is cholera
Cholera is an acute intestinal infectious disease, a legal Class A infectious disease in my country, and one of the quarantine infectious diseases stipulated in the Border Health Quarantine Law. The popularity time in my country is from March to November, and June to September is the peak of the popularity. The cholera incubation period is several hours to 5 days, usually 2 to 3 days. It is contagious during feces positive period, and antibacterial drugs that are effective against Vibrio cholerae can shorten the infectious period.
2
pathogenic bacteria
Vibrio cholerae is the "master of the scenes" that triggers cholera. It is sensitive to dryness, sunlight, heat, acid and general disinfectants. The popular ones include O1 and O139, which can secrete cholera intestinal toxins and cause various human symptoms.
3
Clinical symptoms
In most cases, infection only causes mild diarrhea or no symptoms at all. The typical symptoms are severe painless watery diarrhea, and severe diarrhea more than a dozen times a day. After cholera infection, if the treatment is not timely or inappropriate, it will cause severe dehydration and cause death.
4
infection source
cholera infection source is patients and carriers. The excrement and vomit of cholera patients contain a large amount of Vibrio cholerae. Frequent diarrhea and vomiting can lead to water and food contamination; bacteria carriers include bacteria carriers during incubation, bacteria carriers during recovery, and healthy carriers. Although there are no typical clinical manifestations, bacteria can be carried everywhere.
5
transmission pathway
cholera will not be transmitted through the air, nor can it be directly transmitted through the skin. It is mainly transmitted through the fecal oral pathway. Simply put, it is that disease enters from the mouth. However, if the skin is infected with Vibrio cholerae and does not pay attention to hygiene and wash hands, it may also lead to infection.
6
susceptible population
regardless of race, gender or age, and people are generally susceptible to cholera. A certain amount of immunity can be obtained after illness, but the possibility of reinfection still exists. Especially those living in areas with poor sanitary and medical conditions are the most common people with cholera disease.
7
Treatment Measures
Cholera is very contagious. Once cholera is found to be infected with cholera, both mild or bacteria-carrying people should be isolated and treated. There are no special drugs yet, so we can only undergo symptomatic treatment, and water and electrolytes are replenished in time, supplemented with antibacterial treatment. Those with severe vomiting should stop eating. After the vomiting and diarrhea are relieved, they can give liquid diet . At the same time, attention should be paid to the occurrence of complications.
The symptoms of cholera disappear. After stopping the antibacterial drugs, those who have not detected Vibrio cholerae in fecal culture for two consecutive days can be lifted out of isolation. If you are infected with cholera, you do not receive isolation treatment. It is a violation of the " Law on the Prevention and Control of Infectious Diseases of the People's Republic of China". In addition, patients and bacteria carriers must cooperate with the staff of the Centers for Disease Control and Prevention to do a good job in epidemiological investigations, sampling of close contacts, disinfection of epidemic points at home, etc.
8
How to find out that you are infected with cholera?
has diarrhea symptoms, especially severe painless watery diarrhea. You should go to the hospital immediately and undergo a culture examination for Vibrio cholerae. People who eat with people infected with cholera or have close contact should also collect feces or anal swabs to determine whether they are infected. If you have been to the cholera epidemic area or have recently been to the cholera epidemic area, you should go to the hospital in time and leave feces for bacteriological examination of cholera.
How to prevent cholera?
1
Strengthen personal protection
If citizens go to the country or region where cholera epidemic occurs, please try to avoid direct contact with confirmed cases of cholera or suspected of having symptoms of cholera. If you have any discomfort, please report it actively for timely treatment.
2
Pay attention to dietary safety
Improve environmental sanitation, strengthen drinking water disinfection and food management, protect water sources, prevent pollution, improve drinking water supply conditions, do not eat raw and cold, rotten or spoiled foods, and do not eat raw or semi-cooked aquatic products; develop good personal hygiene habits, wash hands before and after meals, and use the correct hand washing methods.
3
Improve disease resistance
Persist in exercising and improve disease resistance. Key groups such as environmental sanitation, dietary service personnel, medical staff and water residents should be vaccinated in a timely manner.
