The Ministry of Health issued five prevention and control documents on the 9th and deployed diagnostic and treatment protocols for tsutsugamushi disease. It stated that it was initially determined that most of the cases in Hubei and Henan provinces were related to a new virus infection belonging to the family Bunyaviridae.
Monitoring started in May this year
On the 9th, the Ministry of Health issued the "Guidelines for the Prevention and Treatment of Fever with Thrombocytopenia Syndrome" (hereinafter referred to as the "Guide to Prevention and Control"). In recent years, some provinces such as Henan, Hubei, Shandong, and Anhui have discovered and reported fevers and platelets. Reduction in the incidence of infectious diseases is a major manifestation, and a few of the critically ill patients may be due to multiple organ damage and died of treatment.
The main route of transmission of these diseases is locust bites. In May 2010, the China CDC initiated monitoring of cases of fever with thrombocytopenia syndrome in parts of Hubei and Henan provinces.
After the identification of the virus isolated from the patient’s blood, the analysis of the genome-wide sequence, and the double serum antibody neutralization tests in the acute and convalescent stages, it was found that most of the specimens reported in the two provinces belong to the cloth. New viral infections in the Neiaviridae family, and preliminary determination that the detection of fever with thrombocytopenia related to the new virus infection.
A total of two pathogens were found
The reporter learned that at present, the virus naming and further confirmation work is still underway. Therefore, the disease caused by this virus infection is named fever with thrombocytopenia syndrome for the time being.
Experts explained that this type of fever with thrombocytopenia, the pathogens currently found include human granulocytic Anaplasma and a new subtype of Bunia virus. Among them, regarding the prevention and control of human granulocytic anaplasmosis, the Ministry of Health issued the "Guideline for the Prevention and Control of Human Granulocyte Anaeromatism Prevention (Trial)" in 2008. The diagnosis and treatment plan for this time is mainly focused on the infection of the new Bunia virus.
- Progress Table
â—On September 8, many people in Henan Mall died after being bitten by ticks.

- Doubt
1 acute phase of the patient's blood or contagious
The prevention and control guideline stated that cases of this disease have been found in Henan, Hubei, Shandong, Anhui, Liaoning, and Jiangsu provinces. The cases are mainly distributed in the mountains and hilly areas of the above provinces and are highly distributed.
The disease mostly occurs in spring and summer, and may vary slightly in different regions. At the same time, the crowd is generally susceptible.
However, the current route of transmission is still uncertain. In some cases, there was a clear history of locust infestation before onset. No evidence of human transmission has been found. In the acute phase, the patient's blood may be contagious.
2 There is no specific treatment for infected people
Experts said that at present, there is no specific treatment for fever with thrombocytopenia syndrome, mainly for symptomatic and supportive treatment.
However, experts said that the experimental results also showed that ribavirin has an inhibitory effect on this virus and can be clinically tested. Patients with secondary bacterial and fungal infections should be treated with sensitive antibiotics.
It is reported that the incubation period of the disease is not yet very clear, it may be 1 week - 2 weeks. Severely high fever, up to 40 °C or more.
In addition, the Chinese Medicine Council also issued a Chinese medicine diagnosis and treatment program for fever with thrombocytopenia syndrome yesterday. It is considered that this disease belongs to the category of "plague" in Chinese medicine.
3 generally do not need to isolate the patient
"Fever with thrombocytopenia syndrome diagnosis and treatment plan," said under normal circumstances do not need to implement isolation. However, general protective measures should be taken when healthcare personnel and caregivers contact patients.
For example, the patient's blood, secretions, excrement, and the environment and articles that are contaminated by the patient can be treated with high temperature, high pressure, chlorine-containing disinfectants, etc. When salvaging or nursing critical patients, especially when the patient has hemorrhage such as hemoptysis or vomiting, the medical staff and accompanying staff should strengthen personal protection and avoid direct contact with the patient's blood.
However, when the patient's body temperature is normal, the symptoms disappear, and the clinical laboratory test indicators are normal or significantly improved, they can be discharged.
