A Worker in Yunnan Gets Sick and Dies While Resuming Hantavirus, Doctor: Early Detection Can Cure

30 migrant workers in Lincang City, Yunnan Province returned to Shandong on their way back to work. During the journey through Shaanxi, a migrant worker developed hemorrhagic fever and died after rescue. More than 30 people from their colleagues were also collected for examination.

Hantavirus infection is the cause of epidemic hemorrhagic fever in China. On March 24, Xu Tianmin, the chief physician of the Department of Infectious Diseases of the Third People's Hospital of Changzhou, Jiangsu Province, and Yu Gaoping, the director of the Department of Infectious Diseases of the Haiyang People's Hospital of Yantai, Shandong Province, told Peng Mei News (www.thepaper.cn) in their clinical diagnosis and treatment. No person-to-person transmission of the disease has occurred during the experience. For example, none of the escorts and related medical staff had ever detected the infection. Therefore, even in the same car, the patient is unlikely to infect his or her companions.

Xu Tianmin said that the mortality rate of hemorrhagic fever is not high, and most of them can be treated early.

According to Yu Gaoping, he treats patients with epidemic hemorrhagic fever every year. Most of these patients are from rural areas. They are infected with hantavirus due to food or drinking water contaminated by rodent waste such as guinea pigs or direct contact with rodents. Usually within one to two weeks, patients will see a doctor for symptoms of fever. Such patients may also experience symptoms such as gastrointestinal bleeding, vomitus, blood in the stool, and subcutaneous bleeding. If you seek medical treatment early, most can be cured, and some mild patients will even heal themselves. However, due to multiple reasons, a few patients may have more severe symptoms, involving multiple organ systems, and even progressing to critical cases until death.

Xu Tianmin said that epidemic hemorrhagic fever, also called renal syndrome hemorrhagic fever, is because the target organs attacked by hemorrhagic fever are mainly the kidneys.

The main symptoms of the patient during the onset were fever; three pains, including headache, low back pain, orbital pain. Three reds, including red face, cat-like bleeding points on the back and front chest, renal failure, shock.

Xu Tianmin said that in the past, the mortality rate of hemorrhagic fever was very high. The main cause of death was renal failure. "There was no dialysis at that time, the patient did not urinate for seven days, and finally died of renal failure." But now with the dialysis equipment, patients are basically Will not die of renal failure, and there is already a vaccine available, the main cause of death is intractable shock caused by untimely treatment.

On March 24th, the staff of Ningshan County Health and Health Bureau, Ankang City, Shaanxi Province, told Peng Mei News that the first nucleic acid test results show that in the bus involved, except Tian Moumou, the rest of the same crew members had the new crown virus and Hantan.

Viral nucleic acid test results were all negative. At present, two fever patients and one accompanying person are being observed in isolation at the Ningshan County People's Hospital, and the remaining personnel have been placed in a centralized isolation point.

Diagnosis of epidemic hemorrhagic fever

For the diagnosis of epidemic hemorrhagic fever, Yu Gaoping introduced that the diagnosis is relatively easy. Patients usually go to the hospital due to high fever, blood tests, and often find their white blood cells increased, thrombocytopenia, and consider hemorrhagic fever caused by hantavirus infection. It is simple and fast to test with relevant antibody test strips, which can give accurate results within half an hour. Of course, if conditions permit, you can also confirm the diagnosis by detecting viral nucleic acid.

According to Xu Tianmin, the source of infection for hemorrhagic fever is mainly mice. The excreta of mice carrying the virus is dispersed in the air in the form of aerosols and infects people through the respiratory tract. 

Second, humans ingest food contaminated by rat excreta and spread it through the digestive tract. May cause infection. In addition, if humans come in contact with feces of rats, they can spread through wounds, insects and mites. In the 1990s, China was the hardest hit area for hemorrhagic fever. Zhejiang, Jiangsu, Shandong, Anhui, Heilongjiang and other places were all high-incidence areas.
Moreover, hemorrhagic fever has two epidemic peaks in a year. The peak in the first half of the year is from April to June, and the peak in the second half of the year is mainly from November to January.

Why did hemorrhagic fever spread in China for a while, with a large number of cases?

 Xu Tianmin said that in the past, many people participated in agricultural labor and field labor, and worked in farmland all day long, making it easy to come into contact with rats. In addition, in the winter, water conservancy works are popular, and migrant workers live in the wild, causing hemorrhagic fever to occur frequently among migrant workers.

He also said that poor living conditions in the countryside at that time, and that the living space of rats coincided with people more were all the reasons for the high incidence of hemorrhagic fever. In recent years, there have been very few cases of hemorrhagic fever. With the development of agricultural mechanization and the improvement of living conditions, people's exposure to the field has decreased, and their contact with rodents has decreased. The incidence has also dropped. "We only received about five or six cases in 2019," he said, but like fish farmers, who live by the pond and are exposed to the wild are vulnerable to infection.

Prevention of epidemic hemorrhagic fever

For the prevention of epidemic hemorrhagic fever, Yu Gaoping said, kill rats, pay attention to home hygiene and protection during field work, and try to avoid direct contact with rats and feces. Usually pay more attention to clean your hands to prevent food and drinking water pollution, that can effectively prevent the disease. At present, there is an epidemic hemorrhagic fever virus vaccine that can be easily obtained by injection to obtain long-lasting immunity to the disease, which has a very good preventive effect.
