Symptoms of Rickettsia infection

summary

Rickettsial disease is a general term for a variety of acute infections caused by some pathogenic microorganisms in Rickettsiales. It is a worldwide or local epidemic. The clinical manifestations are different. The main vectors of transmission are arthropods, such as ticks, lice, fleas, mites, etc., and it can also be caused by livestock, such as cats, dogs, etc. Symptoms of Rickettsia infection? Let's talk about it

Symptoms of Rickettsia infection

Rickettsia prowazekii is the pathogen of epidemic typhus and typhus. It is short rod shape, 0.8 μ m ~ 2 μ M × 3 μ m ~ 0.6 μ m, or as long as 4 μ m, single or short chain. When people are infected, after 10 to 14 days of incubation period, suddenly onset, severe headache, body pain and high fever, 4 to 7 days after the rash, severe bleeding rash. Some are accompanied by nervous system, cardiovascular system and other parenchymal organ damage. Epidemic typhus is more serious in densely populated and insect flourishing environment. When epidemic, the average mortality rate of patients is 20%, and it can reach 70% in severe cases. The pathogen is transmitted by human louse, so killing louse is an important measure to prevent epidemic typhus.

Rickettsia mooseri is the pathogen of endemic typhus (also known as murine typhus). Its transmission mode is different from that of Rickettsia przewalskii. Its natural host is the house mouse, which is mainly transmitted by the mouse lice in the rat group. If the mouse dies, the mouse lice will leave the mouse and then bite and suck human blood, causing human infection.

Rickettsia rickettsii is the pathogen of typhus in the Rocky Mountains. It was first found in the valley of montpellah in the Rocky Mountains of the United States. When the disease is prevalent, the mortality rate of patients is as high as 90%. Rickettsia rickettsiae parasitizes ticks and the animals they inhabit in nature. People will be infected when they are bitten by ticks.

matters needing attention

For critically ill patients, symptomatic support therapy is very important. When severe patients have respiratory distress, ventilator assisted breathing can be considered. When acute renal insufficiency, dialysis can be considered. At the same time, attention should be paid to correct anemia and coagulation dysfunction.
