According to official reports from Shaanxi Provincial Center for Disease Control and Prevention and Xi’an Center for Disease Control and Prevention,Since the beginning of winter, Xi’an has successively received many cases of hemorrhagic fever, which has always been the city with the peak incidence of hemorrhagic fever. The main source of infection is Apodemus agrarius.

Hemorrhagic fever, the full name of hemorrhagic fever with renal syndrome, is a natural foci disease caused by Hantavirus, and rodents (Apodemus agrarianus and Rattus norvegicus) carry the virus and spread. It is clinically characterized by fever, hemorrhage and kidney damage As the main feature.

The disease can occur throughout the year, and there are two peaks of incidence each year, of which there will be a large peak from October to January of the following year, called the autumn and winter peak, and a small peak from April to June (or May to July) , Called Chunfeng.

It can be transmitted through a variety of ways, including contact transmission, respiratory transmission, digestive tract transmission, mite vector transmission, and vertical transmission.

The most common infections are infections caused by contact with the excreta (saliva, urine, feces, etc.) of virus-carrying animals, or infections caused by ingestion of food and water contaminated by venomous rodents, and inhalation of feces contaminated by venomous rodents Aerosol infection.

After the human body is infected with the virus, after an incubation period of about 2 weeks, symptoms such as chills and fever, “three pains” (headache, low back pain, orbital pain) and “three reds” (redness of the face, neck and upper chest) appear.

Data show that from January to August 2020, the number of epidemic hemorrhagic fever in China was 4,359 cases, and the death toll was 21; in 2019, the number of epidemic hemorrhagic fever cases in China was 9,596, and the death toll was 44.The overall average mortality rate in the past two years was 0.47%.

Song Rui, chief physician of the Infectious Disease Diagnosis and Treatment Center of Beijing Ditan Hospital, pointed out: “Hemorrhagic fever is not a respiratory infectious disease such as SARS and influenza A, and it will not spread from person to person, Is mainly spread by contact after contaminated by rodent secretions or excrement, so there will be no large-scale leap-over infection. “

The Xi’an Center for Disease Control and Prevention reminded that the current peak period of hemorrhagic fever is also a period of high incidence of respiratory infectious diseases. The symptoms of hemorrhagic fever in the early stage of onset are similar to those of colds and fevers, which can easily be ignored and delayed treatment. If symptoms such as colds and fever occur at this time, be wary of hemorrhagic fever and go to a regular hospital for treatment immediately. Do not take your own medicine to avoid delaying the condition.

At the same time, the following protective measures should be taken:

1. Anti-rodent and anti-rodent:

Heatstroke prevention and rodent control are the key to preventing the epidemic.

The rodent board can be used to kill rodents to block the rodent holes to prevent wild mice from entering the room; poison bait can also be put in, rodent-proof boards are used at the door, sewer gates and wire mesh are used to prevent rodents from entering.
