Dengue virus has four confirmed serotypes; infection with one type usually gives lifelong immunity to that type, but only short-term immunity to the others. Subsequent infection with a different type increases the risk of severe complications. [9] The symptoms of dengue resemble many other diseases including malaria, influenza, and Zika. [10]
In a small proportion of cases the disease develops into the life-threatening dengue hemorrhagic fever, resulting in hemorrhage, thrombocytopenia and blood plasma leakage, or into dengue shock syndrome, where shock occurs. Dengue is transmitted by several species of mosquito within the genus Aedes, principally A. aegypti.
The symptoms experienced by those infected with dengue can vary widely: up to 80% of dengue cases are asymptomatic, and while some infections may trigger only flu-like symptoms, more serious cases ...
The Skeeter syndrome should not be confused with another type of reactivity to mosquito bites, severe mosquito bite allergy (SMBA). SMBA is most often an Epstein-Barr virus-associated lymphoproliferative disease that complicates ~33% of individuals with chronic active Epstein-Barr virus infection or, in extremely rare cases, individuals with Epstein-Barr virus-positive Hodgkin disease or an ...
