Zikavirus is among the most contagious diseases today. It is avector-borne disease majorly transmitted by the Aedes mosquitothrough mosquito bites. The infected Aedes mosquito that carries thevirus also spreads chikungunya and dengue virus. People infected withZika do not show specific symptoms related to the disease, but onlymild signs, similar to other symptoms of any virus transmitted by anarthropod. The symptoms include skin rashes, eye redness, headache,muscle and joint pain, and body fatigue(WHO, 2017).The symptoms persist up to a week, and it is through blood or urinetest that the diagnosis confirms Zika infection.

Anyonecan contract Zika virus as long as one gets exposure to an area thathas the prevalence of the Zika virus. Most people who get the diseaseare people who travel to regions infested with the virus. Also, anyindividual bitten by a mosquito carrying the virus is likely to getinfected. Zika virus can be congenital, where the mother passes thevirus to the fetus when pregnant or during birth. Zika is responsiblefor microcephaly in children(CDC, 2016).In addition, sexual transmission of Zika Virus from an infectedperson whose symptoms are not yet visible to his or her partner cancause the disease. In French, some blood donors with Zika confirmedthe presence of the virus in the blood and incidences in Brazilindicate the spread of Zika from the blood transfusion. Finally,laboratory exposure to the Zika Virus forms a transmission avenue forthe disease. However, if an individual contracts Zika virus and thetransmission mode established, it becomes easy to prevent futureinfections.

Thereis no vaccine for preventing Zika virus infections. Additionally,Zika does not have a particular treatment, but depending ondirectives given by the physician’s advice, people with Zika virusshould take adequate fluids, get enough rest and the present pain andfever is treated with ordinary medicines. Nonetheless, one shouldseek medical attention if the symptoms persist. The only means ofprotecting one from getting Zika virus is by implementing preventionmeasures to counter transmitting agencies. For instance, one shouldwear protective clothes from mosquito bites, sleep under mosquitonets, use mosquito repellant spray, clear mosquito breeding areas anddrain stagnant water. The medics should screen blood beforeundertaking blood transfusion to overrule the presence of Zika virus,while people should be educated of possible transmission of Zikavirus through intercourse to practice safe sex or abstinence(WHO, 2017).

Zikavirus has been in existence for around six decades. It was discoveredin 1947 in Uganda in a monkey, identified in people in 1952 and laterspread to other regions such as Brazil, which recorded Zika virusrelated infections in 2015(WHO, 2017).Zika virus continues to spread throughout the world. The CDC reporton the current situation in The Bahamas indicates that the mosquitoesin the region are infected with Zika virus and passing it to thepeople(CDC, 2016).Thus, individuals who travel to The Bahamas are advised to protectthemselves from mosquito bites. WHO commits to support expertresearch on Zika virus and strengthen the capacity of healthauthorities to implement control measures to reduce the population ofAedes mosquito. Therefore, Zika virus is a global menace due to itsinternational spread and the proclamation by WHO that it is a publichealth emergency.
