Mild cases of dengue fever can easily be confused with several common diseases including Influenza, measles, chikungunya, and zika. [61] [62] Dengue, chikungunya and zika share the same mode of transmission (Aedes mosquitoes) and are often endemic in the same regions, so that it is possible to be infected simultaneously by more than one disease ...
Over the last twenty years, there has been a geographic spread of the disease. Dengue incidence rates have risen sharply within urban areas which have recently become endemic hot spots for the disease. [61] The recent spread of Dengue can also be attributed to rapid population growth, increased coagulation in urban areas, and global travel.
Dengue virus (DENV) is the cause of dengue fever.It is a mosquito-borne, single positive-stranded RNA virus of the family Flaviviridae; genus Flavivirus. [1] [2] Four serotypes of the virus have been found, and a reported fifth has yet to be confirmed, [3] [4] [5] all of which can cause the full spectrum of disease. [1]
A woman whose menstrual cycles ranged in length from 30 to 36 days would be estimated to be infertile for the first 11 days of her cycle (30-19=11), to be fertile on days 12–25, and to resume infertility on day 26 (36-10=26). When used to avoid pregnancy, such fertility awareness-based methods have a typical-use failure rate of 25% per year. [18]

The process of climate change has produced abundant rains and high temperatures, (a phenomenon called tropicalization) favouring the reproduction of the mosquito that transmits the dengue virus, advancing the epidemic this year by several weeks compared to previous seasons, which historically, Infection peaks tended to occur between March and April, suggesting a continued increase in cases.
