Flaccid fever is also known as septic fever. It is a condition in which the body temperature is consistently above 39 degrees, with large fluctuations, and the range of temperature fluctuation is more than 2 degrees in 24 hours, but all are above normal level. The temperature of human body is formed by the heat generated from metabolic activities, skeletal muscle movements, etc. The balance of heat production and heat dissipation in the body is maintained through the thermoregulatory center in the lower thalamus, so the body temperature of normal people is relatively constant. The temperature of a normal person is relatively constant, but sometimes varies slightly depending on the time of measurement, location, age, diet, and exercise. So, what are the causes of persistent flaccid fever? The following is a brief introduction: 1. Infectious sources:The main infectious sources associated with humans are sheep, cattle and pigs, followed by dogs. Patients can also discharge bacteria from feces, urine and milk, but instances of human-to-human transmission are rarely seen.
2, the transmission route: through the skin mucous membrane contact infection, through the gastrointestinal tract infection, through the respiratory tract infection.
3.Susceptible people: Humans are generally susceptible, and they can obtain certain immunity after the disease, and there is cross-immunity between different species of Brucella, and there are 2-7% of re-infection, and residents of infected areas can be immunized because of recessive disease.
