Strawberry is the "mastermind" of haemorrhagic fever
Recently, hemorrhagic fever-related topics have been on the hot search list on social media and attracted attention.
The rumors ranged from "rats eating strawberries everywhere causing hemorrhagic fever" to "eating strawberries causing hemorrhagic fever", and once let strawberries lie down.
What is hemorrhagic fever?
Who is spreading hemorrhagic fever?
Will I get hemorrhagic fever if I eat strawberries?
In response to recent reports of hemorrhagic fever in many places, experts from the Beijing Centers for Disease Control and Prevention said that the "mastermind" of this disease is actually it, and it is important to understand prevention knowledge.
No more than 10 cases per year in Beijing
Epidemic hemorrhagic fever, also known internationally as hemorrhagic fever with renal syndrome, is a severe acute infectious disease that is transmitted by rats and caused by Hantavirus, and clinically characterized by fever, bleeding and kidney damage.
The population is generally susceptible, with a case fatality rate of about 1%.
It is understood that my country is a large country with hemorrhagic fever with renal syndrome, and 90% of the global cases occur in my country.
The disease was first discovered in China in 1931, and it was classified as a Class B infectious disease in 1956.
In most areas, there are varying degrees of incidence or epidemic every year.
In Beijing, the main type is house mouse, and the number of cases has been less than 10 in recent years.
Most people only have fever and are easily confused with a cold
After being infected with Hantavirus, more than 80% of people will have a dominant disease.
A typical case has five clinical stages, that is, the main manifestations are fever, symptoms of systemic poisoning, symptoms of capillary damage, and kidney damage.
Sun Yulan, deputy chief technician of the Municipal Center for Disease Control and Prevention, said that the symptoms of systemic poisoning include body aches, headaches, low back pain and orbital pain. Headache, low back pain and orbital pain are generally referred to as "three pains"; capillary damage is the main manifestation It is a sign of hyperemia, bleeding, and exudative edema.
Skin congestion is common in the face, neck and upper chest skin congestion and flushing, that is, "three reds".
However, most cases have mild symptoms, with only mild symptoms such as fever, which can be easily confused with a cold.
Currently, there are no specific drugs for hemorrhagic fever with renal syndrome, and most of them are supportive treatments.
As long as the patient achieves "three early and one treatment": early detection, early rest, early treatment and nearby treatment, most people have a good prognosis.
Hemorrhagic fever is transmitted to people by it
Sun Yulan introduced that humans are not the source of infection, and it is generally believed that hemorrhagic fever with renal syndrome will not be transmitted from person to person.
The disease itself has nothing to do with eating strawberries. The mouse with the virus is the "culprit."
According to different host mouse species, hemorrhagic fever with renal syndrome can be divided into apodemus type (transmitted by Apodemus agrarius, etc.) and house mouse type (transmitted by Rattus norvegicus, etc.). The disease of the apodemus type is more serious, and the peak season of onset is autumn. In winter, the type of house mouse is relatively mild, and the incidence is mostly in spring.
There are three main ways of transmission of hemorrhagic fever with renal syndrome:
Infected by virus-carrying mice to humans, mice bite human skin or mice’s urine, feces, saliva contaminate the wounded skin and mucous membrane; mice’s urine, feces, saliva contaminate food; mice’s urine, feces, saliva contaminate dust When raised, it is inhaled into the human respiratory tract.
Parasitic mites The mites that live on mice or in holes bite people.
The incubation period of vertical mother-to-child transmission is usually 7 to 14 days, and occasionally as short as 4 days or as long as 2 months.
There is nothing terrible about mastering the prevention method of hemorrhagic fever
Rodent and rodent prevention of hemorrhagic fever with renal syndrome is a natural foci disease mainly transmitted by rodents. Rodent and rodent prevention is a successful experience and main measure to prevent and treat hemorrhagic fever with renal syndrome.
Clean the environment and improve indoor and outdoor environmental sanitation.
Keep the room dry and ventilated, and keep no sundries and food under the bed; remove the accumulated garbage in time; kill and prevent mites.
Do not provide breeding space for rats, clean the utility room regularly; wear masks and gloves during the cleaning process, and do a good job of disinfection.
Beware of disease from the mouth to do food hygiene, food disinfection and food preservation; food, food, etc. should be stored in tight and seamless containers, and covered to prevent rodent contamination, do not expose and store; do not eat by rodents Nibbled vegetables, fruits and other foods.
In the wild, pay attention to protection. Do not directly touch the rodents and their excrement with your hands, do not sit on the grass or haystacks, and pay attention to protect the skin to prevent cuts or mite bites.
Vaccination against hemorrhagic fever my country has developed a bivalent inactivated vaccine for hemorrhagic fever with renal syndrome, which is the most economical and effective measure to prevent hemorrhagic fever.
