Schistosomiasis, also known as bilharziasis or snail fever
Amoebic dysentery is caused by the protozoan parasite Entamoeba histolytica, not a vector in the traditional sense like insects. The infection is typically transmitted through contaminated water or food, often in areas with poor sanitation. Individuals can also spread the cysts through fecal-oral transmission. Thus, while there is no specific vector, contaminated sources play a crucial role in the transmission of the disease.
Schistosomiasis is a parasitic disease caused by flatworms called schistosomes. It is a significant cause of morbidity and mortality in many parts of the world, particularly in tropical and subtropical regions. Prevention strategies include controlling the freshwater snails that act as intermediate hosts for the parasite, providing access to safe water sources, and promoting hygiene practices. Treatment involves medication to kill the worms.
It is called a vector
It is caused by the bacterium Yersinia pestis, which is normally carried by fleas. So technically every animal who has fleas can carry the above bacterium, and therefore any animal may be carrying the black death. However this bacterium left Europe in the 19th century.
The vector is how the illness is spread. In cholera's case, the vector is contaminated water. That is how cholera is spread.
Polio was spread human-to-human, not by a vector.
A disease which is carried and spread by an agent (animal or microorganism) is a vector spread disease. Eg. Mosquitoes are the vectors for malaria.
what is the role of a vector in the spread of a disease
There is no vector of strep throat. I spread by droplet infection.
Chlamydia trachomatis doesn't have a vector. It is spread by infected humans.
Snails can transmit diseases such as rat lungworm (Angiostrongylus cantonensis) and schistosomiasis to humans. These diseases can be contracted through contact with contaminated snails or their slime.
There is no vector for the spread of TB.It is primarily spread person to person
no its only spread from person to person
The Aswan High Dam was built in Egypt. The dam prevented annual flooding, which had previously limited the spread of schistosomiasis. Once the flooding ceased, snails that carry the parasite were able to thrive in the stagnant water created by the dam, leading to a surge in schistosomiasis cases.
