Typhoid and Paratyphoid

The disease is distributed throughout China and is distributed throughout the year, with the largest number in summer and autumn, and the incidence is in children, with more young adults. Clinically, it is characterized by persistent high fever, relative pulse slowness, characteristic poisoning symptoms, splenomegaly, roseola and leukopenia. Intestinal bleeding and intestinal perforation are the main complications. The main pathological feature of typhoid fever is the hyperplasia response of the whole body's reticular endothelial system, with the most prominent pathological changes in the lymphatic tissue of the lower ileum. Paratyphoid fever is caused by Paratyphoid A, B, and Propionibacterium. Its clinical manifestations, diagnosis, treatment and prevention are the same as typhoid fever.
