Cryptosporidiosis is a parasitic disease caused by Cryptosporidium parasites, which are transmitted through contaminated food or water sources. The disease primarily affects the gastrointestinal tract, causing symptoms such as diarrhea, stomach cramps, and dehydration. It is particularly dangerous for individuals with weakened immune systems, such as those with HIV/AIDS or undergoing chemotherapy. Research in cryptosporidiosis focuses on understanding the biology and transmission of Cryptosporidium parasites, developing effective diagnostic methods, and exploring treatment and prevention strategies. This includes studying the parasite's lifecycle, identifying risk factors for transmission, and examining potential vaccines or therapeutic interventions. Additionally, researchers are investigating strategies for improving water and food safety to reduce the spread of cryptosporidiosis.
