Amenorrhoea is a symptom with many potential causes. Primary amenorrhoea (menstrual cycles never starting) may be caused by developmental problems such as the congenital absence of the uterus, failure of the ovary to receive or maintain egg cells. Also, delay in pubertal development will lead to primary amenorrhoea.
Diseases transmitted by mosquitoes include: malaria, dengue, West Nile virus, chikungunya, yellow fever, filariasis, Japanese encephalitis, Saint Louis encephalitis, Western equine encephalitis, Eastern equine encephalitis, Venezuelan equine encephalitis, La Crosse encephalitis and Zika fever.
The specific mosquitoes are of the Aedes genus and the most common carriers of Tropical Flu are the Aedes Aegypti species. Malaria is also caused by carrier mosquitoes, but the pathogen in malaria is a parasite called plasmodium, rather than viruses that mosquitoes carry that cause Dengue Fever.
