Dengue is a viral disease transmitted by the bite of a mosquito found mainly in tropical and subtropical areas. The dengue virus causes high fever, muscle and joint pain, rashes and, in some cases, hemorrhagic complications. There are four serotypes of the virus, meaning a person can become infected more than once.
Transmission occurs exclusively through the bite of an infected mosquito, not through direct contact between people. At present, there is no specific treatment that cures dengue, although mild cases are managed with rest, hydration and medication to reduce fever and pain.
Verotoxigenic Escherichia coli infection is caused by certain strains of this bacterium that produce toxins and can cause symptoms such as diarrhea, abdominal pain and, in the most severe cases, kidney complications. It is usually transmitted by consuming contaminated food or water. Typhoid fever, meanwhile, is an infectious disease caused by the bacterium Salmonella Typhi, which can cause high fever, headache, general malaise and abdominal discomfort. It is mainly transmitted by consuming contaminated water or food and requires antibiotic treatment.
