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.
Because certain bites can also spread illnesses, such as the Zika virus and West Nile virus (both transmitted by mosquito), Lyme disease (from a black-legged tick), Rocky Mountain spotted fever (from a dog or wood tick), or Chagas disease (from kissing bugs), it's good to know what bit you.
