  Transmission: Dengue fever is caused by a virus with four serotypes: 1,2,3 and 4 meaning  a person can be infected four times but after receiving one of the viruses they  would only be able to catch the other three forms of Dengue. Aedes mosquitoes (A. aegypti or aedes albopictus) act as vectors for human transmission along with being the vector for other viruses such as Chikungunya and Zika. Dengue can also be passed through breastfeeding, organ transplantation and blood transfusion but few cases have occurred.

  
   

  Symptoms: One in four people will become sick from Dengue resulting in eye pain, headache, muscle pain, rash, nausea and vomiting along with bone and joint pain. Symptoms can be mild or severe and will typically lasts two to seven days. One in twenty people will develop severe Dengue resulting in shock, internal bleeding, and even death. People who have had a Dengue infection are more likely to develop DHF or DSS in the future. 
  

  Treatment: Currently, no treatment exists for Dengue. It is suggested to watch for an advancement of symptoms and rehydrate in case of dehydration and fever.  

  Risk: Dengue’s transmission history throughout the world points to the virus favoring climates such as those found in the tropics. 

  Prevention: Be aware of the locations of travel and current epidemiological factors. Protect against mosquito bites with approved mosquito repellent, long pants, and boots.
• 1 2019-07-22T12:15:33-07:00 Zika Transmission 3 plain 2019-07-23T11:46:50-07:00

  Transmission: Aedes Aegypti and Aedes Albopictus transmit Zika virus between people. Zika research has also found cases of congenital transmission along with sex and possibly blood transfusion. 
  

   

  Symptoms: Some cases will not have symptoms or they may be very mild. Symptoms include rash, fever, joint pain, red eyes, and muscle pain. There have only been a small amount of cases in which death occurs due to infection. Fetuses that have contracted Zika may be born with microcephaly and severe brain defects. Pregnant women may have miscarriages, stillbirths and other birth defects. Zika may also cause Guillain-Barre Syndrome in which a person's immune system attacks the nerve cells of that person. Rarely will Zika cause severe symptoms such as bleeding, bruising, slow blood clotting or swelling of the brain and spinal cord. 

  Risk: Living within the tropical region which is most suitable for mosquito proliferation. 

  Treatment: Currently there is no treatment but to treat the symptoms. If needed hospitals are supposed to be equipped to provide supportive care. 

  Prevention: Be aware of current epidemiological trends when traveling and wear protective layers that protect against mosquito bites. Use mosquito repellent as well as avoiding being bitten.
