Can schistosome liver disease be transmitted

summary

Although I am also a medical worker, I have never heard of schistosomiasis liver disease before, but my father was found to have this disease, and my family is also worried about schistosomiasis liver disease. Now let's popularize the science about whether schistosomiasis liver disease can be infectious.

Can schistosome liver disease be transmitted

First, schistosomiasis liver disease is not infectious, mainly because the eggs of Schistosoma are deposited in the liver tissue when they flow through the portal vein system, which can form egg granuloma. In the calcified eggs, the miracidia released antigen, the granuloma shrank, the eggs disappeared and replaced by fibrosis.

Second: it can lead to cirrhosis, hepatosplenomegaly, portal hypertension and other syndromes. However, the schistosome that does not flow through the liver enters the intestinal cavity through the intestinal wall and enters into the water with the excretion of feces. The miracidium can enter the snail and develop into cercariae. Cercariae can penetrate into the skin of the host and infect the host. People can also eat snails to infect schistosomiasis.

Third, the route of transmission. In each link of the transmission route, the feces containing schistosome eggs pollute the water source, the existence of snails and people's contact with infected water are three important links. The main pathological changes of schistosomiasis occur after the incubation period, that is, after the larva develops and lays eggs. Due to the stimulation of mechanical and egg toxin, phlebitis, especially the colon, mesentery and liver, is caused by the egg. The pathological changes caused by the egg are more extensive and serious than those caused by the adult. Therefore, it can be considered that "the pathological changes of schistosomiasis are caused by the egg".

matters needing attention

Schistosomiasis liver disease sounds very frightening, in fact, as long as the heart with the doctor's treatment, coupled with the family's careful care, add a little more nutrition, so that the treatment will be twice as effective, this disease is generally not infectious Oh!
