Preview: Today I am going to inform you about the history of the Zika virus, how it can be transmitted and precautions that can be taken in order to keep clear of this virus. Body: I. Main Point 1: According to an Article on Centers for Disease Control and Prevention website, published on June 20, 2016 - Zika was first discovered in 1947, named after the Zika Forest in Uganda. Sub-point 1: In 1952, the first human cases of Zika were detected and since then, outbreaks of Zika have been reported in tropical Africa, Southeast Asia, and the Pacific Islands. B. Sub-point 2: Before 2007, at least 14 cases of Zika had been documented.
“Only certain countries in the world have the mosquito required to carry this virus. Some types of Aedes mosquito can spread the Zika virus, particularly Aedes Aegypti but also possibly Aedes Albopictus. Australia is home to the Aedes Aegypti mosquito that can carry the virus, this mosquito is currently found in parts of Northern, Central and Southwest Queensland. Aedes Albopictus is found in the Torres Strait Islands” (Department of Health, 2018). This means that the Zika virus can be transmitted to Australia however, the only cases found in Australia are from people who received the virus overseas and brought it back with
In conclusion, Zika virus is a mosquito transmitted infection that originated from Africa. Discovered in Zika Forest near Lake Victoria in Uganda, Africa almost seventy years ago on April 18, 1947 on a rhesus monkey, Rhesus 766. It is discovered in the Rockefeller Foundation Program because of the research about the jungle yellow fever. By then, they brought Rhesus 766 where they examine the febrile monkey and pass sample of serum from the rhesus to mice where they found out after 10 days that the mice that have been inoculated were sick, and a filterable and transmissible agent was found naming it the Zika Virus (ZIKV). In early 1948, ZIKV was also isolated from Aedes Africanus mosquitos trapped in the same forest.
Main Point 3: When in an area where Zika is common, or there are many mosquitos, some precautions are to be taken to stay clear of the virus. Sub-Point 1: It is recommended that when you are in a tropical country, you must use insect repellents. You should also wear long sleeves and pants, and sleep under a mosquito net. Sub-Point 2: If you are coming back from another island or you are infected it is important to visit the doctors within 2 weeks. (transition) We are learning something new about Zika everyday, whether good or bad.
Zika is a perfect example of how infectious diseases and agents can quickly spread throughout the world due to the ease of travel, and therefore poses a major public health threat. The public health goal is to now figure out how to stop the spread of Zika by possibly eliminating the reservoir and vector, the mosquito. Prevention of Zika also depends on educating at risk populations/geographical areas on the disease and how to avoid becoming infected.There are also a multitude of neglected tropical diseases in parts of the world that receive little attention and therefore little research to prevent mortality and
“Until a vaccination is found for the Zika Virus, we have to take safety precautions. It is most important that pregnant women do not travel to places where there are known cases of the Zika Virus, i.e., South America, Central America, Caribbean, Miami, Florida and Tampa, Florida. The greatest way to prevent Zika would be preventing mosquito bites. Wearing mosquito and bug repellant when you’re out can help. If you’re not able to wear repellants, you should cover your skin with long clothing.
The government relief was created for the citizens of Canada, as they were not producing enough income for their family. A typical ration included flour, pork, split peas, corn meal, molasses, and cocoa. Although a relief was created, It provided for only about half of a person’s
Malaria Overview- Malaria is an existence debilitating blood disease created by parasites transmitted to people through the nibble of the Anopheles mosquito. Once an infected mosquito nibbles a human and transmits the parasites, those parasites duplicate in the host's liver before contaminating and obliterating red platelets. The disorder can be controlled and treated if analysed right off the bat. Lamentably, this is impractical in a few zones of the world ailing in therapeutic offices, where jungle fever flare-ups can happen. Causes- Malaria fever is brought on by the nibbles from the female Anopheles mosquito, which then contaminates the body with the parasite Plasmodium.

These two sudden outbreaks infected more than 284 people. Later in a village close to Ebola River more outbreaks started to happen and that’s where they named the virus after. Many scientists and researchers had
Dengue has been the most common disease in human. It is transmitted by 2 species of genus Aedes mosquitoes namely, Aedes aegypti (principal vector) and Aedes albopictus (Department of Health of the Philippines, 2016), which are widely distributed in subtropical and tropical areas of the world. A study from Yboa & Labrague (2013) expressed that out of the 2.5 billion individuals in danger internationally; around 1.8 billion or more than 70 percent of them live in the Asia-Pacific locale. According to Shepherd (2017), there are 2.5-3 billion people live in approximately 112 countries encounter dengue transmission. In addition, the global incidence of dengue has expanded with an estimated 40%-50% of the total populace in 128 countries in danger.
