What causes epidemic hemorrhagic fever? How to prevent it?

Epidemic hemorrhagic fever, also known as hemorrhagic fever with renal syndrome, is a severe acute infectious disease with fever, hemorrhage, and kidney damage as the main symptoms, caused by hantavirus. It has an acute onset, a serious illness, a high mortality rate, and is very harmful to people's health. Most haemorrhagic fever viruses are transmitted by rats with the virus, so rodent prevention and rodent extermination are key to preventing disease.

At present, vaccination is the most important preventive measure, i.e., before the epidemic, vaccination against hemorrhagic fever can effectively prevent viral infection.

Once the cause of fever is unknown, contact with rats, food bitten by rats, and bitten by rats, you must go to a regular hospital in time, early detection, early diagnosis, early rest, early **, and nearby ** are the basic requirements for reducing the mortality rate of hemorrhagic fever. Vaccinations 3 times, with an interval of 14 days between the first two vaccinations. It's also worth noting that the second injection for any reason is not timely.

If administered on time, this round of hemorrhagic fever will restart immunization. At the same time, it is important to note that the HFRS vaccine is an inactivated vaccine (dead virus vaccine), and the vaccine does not cause HFRS to occur due to infection with live virus.

In addition to clinical blood fever, in addition to clinical **, I think we should also strengthen dietary care. The study found that the duration of the patient's disease was significantly shortened by the care of the patient's diet. The disease is clinically divided into five stages: febrile stage, hypotensive shock stage, oliguric stage, polyuria stage and recovery stage, and the diet is different in different periods.

**Mostly symptomatic**. Early detection, early rest, early ** and local isolation ** are the principles of disposal. At the same time, the local disease control situation is reported according to the category B infectious diseases.

Individuals should try to strengthen their personal protection against contact with infection. Avoid contact with rodents and their excreta (urine, feces) or secretions (saliva, etc.); Do not eat food, water, and drinks contaminated with rats; Avoid mucosal damage. If there is damage, iodine should be disinfected.

Wear a mask, hat and gloves when cleaning up dirty debris and waste. There are almost no infections between people, so there is no need to worry.

In fact, it is a cold type of disease, and it will have a great impact on the body, the injury is also a virus infection or serious harm to the respiratory tract, and the digestive tract will also be affected.

Epidemic hemorrhagic fever is caused by hantavirus, mainly by rodents as the main source of infection, usually must not be in contact with mice, if there are symptoms, must also be detected early, early rest and early **.

Epidemic haemorrhagic fever is an infectious disease caused by a viral infection; We should do a good job of rodent extermination, rodent prevention, wash hands frequently, and avoid contact with sick patients.

Epidemic haemorrhagic fever is an acute systemic illness transmitted by wild rats such as the Haddock squirrel. In China, because epidemic hemorrhagic fever is mostly accompanied by renal impairment, it is also called renal syndrome hemorrhagic fever, referred to as "outflow fever", which is caused by a virus called hantan. According to reports, China is the country most seriously affected by "outflow fever" in the world, with 460,000 cases occurring every year in the past 10 years, and there are sporadic cases throughout the year, with the peak period of the incidence being March and May every year, and the area is widely distributed.

The epidemic was mainly in rural areas in the past, but now it has spread to some central cities, and the population is generally susceptible, with a high incidence of floating population, young and middle-aged people are more likely to have a search and search, children are rare, and males are higher than females. Therefore, the disease is still a viral infectious disease that seriously threatens people's health in addition to viral hepatitis in China.

There are more than 90 species of host animals that are the source of infection of the disease, but they are mainly transmitted to humans through rodents. Secondly, rabbits, cats, dogs, poultry, etc., all have the possibility of transmitting the virus. The virus invades the human body through the blood, saliva, feces, and urine of these animals, from the damaged **, mucous membranes (such as the digestive tract), and can also be caused by the bite of mites parasitic on rodents, and even through the respiratory tract inhalation through the dust contaminated by excrement.

In view of the fact that outflow fever is mainly prevalent in rural areas and floating populations, when working in the field and sleeping in the suburbs, try to achieve three taboos: first, avoid lying and sleeping in the mountains, forests and grasses; 2. Do not dry bedding and clothes on the lawn; 3. Don't wear clothes and pants ** too exposed. Urban residents should keep a certain distance from domesticated cats, dogs and other pets to avoid being scratched by pets.

In addition, vaccination against epidemic hemorrhagic fever has a certain protective effect. When a family member or neighbor suffers from outflow fever, the patient should first be sent to an infectious disease hospital for isolation**, and the food that the patient has eaten should not be eaten again, and the clothes worn by the patient should be exposed to the sun for 4 hours, or soaked, washed, and dried with a disinfectant solution before being reused.

At present, there is no special ** for this disease, and the principle is still "three mornings" and "one on".

Early detection, early diagnosis, early rest, proximity**. Prophylactic and fluid-based comprehensive measures are the basis of "outflow fever", and the key is to control shock, hemorrhage and kidney failure. Once the diagnosis is confirmed, early haemodialysis can reduce the mortality rate.

Practice has proved that with the implementation of foresight, the case fatality rate has dropped from 20 30 in the past to 3 10. Some scholars have pointed out that patients with heavy bleeding, low urine output, coma, prolonged prothrombin time, pulmonary edema, heart failure, intracranial hemorrhage, secondary infection, stage II or stage III overlap and multi-organ failure should go to a qualified hospital in time to improve the curative effect.

Hemorrhagic fever is an infectious disease that causes bleeding, also known as hemorrhagic fever syndrome. Common hemorrhagic fevers include Ebola virus disease, lead hepatitis C, dengue fever, bush fever, Lassa fever, etc. Here are the **, symptoms, and ** methods of hemorrhagic fever:

**: Hemorrhagic fever is an infectious disease caused by viruses, bacteria, and parasites. These pathogens can be transmitted to humans through blood or body fluids, usually through contaminated needles, mosquito bites, airborne transmission, etc.

Poor symptoms take the sharp shape:

Symptoms of hemorrhagic fever usually include fever, headache, muscle pain, nausea and vomiting. In the course of its further development, patients may develop symptoms such as mild bleeding, jaundice, abnormal liver function, kidney failure, etc. After haemorrhagic fever virus infection, the disease can become severe within a short period of time (a few days to two weeks), with 100 cases of general ecchymosis and bleeding.

Methods: Hemorrhagic fever needs to be diagnosed as early as possible in order to increase the rate. Typical measures include support (e.g., fluid infusion, symptom relief, electrolyte and acid-base balance, etc.) as well as antimicrobials and antivirals.

However, there is no specific drug for hemorrhagic fever. Therefore, important preventive measures include strengthening personal hygiene, paying attention to food hygiene, and preventing mosquito bites.

First of all, we must pay attention to the diet, we must eat a light diet, we must not eat too greasy, we must eat more fresh vegetables and fruits, such as apples, bananas, oranges, oranges, grapefruits, lettuce, greens, tomatoes, carrots, cucumbers and other foods, and we must also pay attention to the routine of work and rest, do not stay up late.

We must do a good job of protecting each other when we go out, and we must clean our own hygiene and body when we go home.

Pay attention to cleanliness and hygiene, pay attention to disinfection work, prepare measures in advance, pay attention to the improvement of immunity, and do not go to dangerous places.

Epidemic hemorrhagic fever is the most common type of viral hemorrhagic fever, which is a natural epidemic caused by hantavirus and is a group of acute viral infectious diseases with fever, hemorrhage and renal impairment as the main clinical features. The disease was first seen in the Vladivostok region of the former Soviet Union in 1913. In 1935, the disease was first discovered in Sunwu County, Heilongjiang Province, and was called "Hulin fever", "Sunwu fever", "Sandaogang fever" and so on.

In 1942, it was named epidemic hemorrhagic fever, and in 1982, it was uniformly named renal syndrome hemorrhagic fever by the World Health Organization, and China now uses this name.

The causative agent of the disease is hantavirus. The virus was first isolated from the lung tissue of the black rat that was first captured by Professor Lee Ho-wang of Korea University in South Korea in 1976 from the Hantan River near the 38th parallel, hence the name.
