Name: BriAnna Davis Causative Agent: Zika virus Disease: Zika, including microcephaly and Guillian barre syndrome Classification of the causative agent: Z. virus is associated with the genus Flavivirus and the Flaviviridae family. Zika is in the same category of diseases with yellow fever and West Nile virus. The Zika virus has an enveloped capsule with single-strained RNA genome. The virus encodes polyproteins with three structural proteins and seven non-structural proteins.
History: The Z. virus was first seen in a monkey in 1947. It wasn’t until a year later in 1958 that the mosquitoes were known to be host. The first case reported for Zika found in humans was in 1954, by a 10-year old Nigeran girl. Virulence factors of the causative agent:

The lack of effective mosquito control is a big part into the spread of Z. virus. The increased amount of traveling plays a role in the spread as well. Mode of transmission: Zika is primarily transmitted by arthropod transmission. The bite of an infected Ades mosquito is what causes the disease. Mosquitoes also lay eggs in or near standing water such as buckets, bowls, and flower pots. Mosquitoes can get the Z. virus from humans by feeding on an infected person. Mosquitoes are not the only way to contract the Z. virus. Pregnant mothers can transfer the virus during pregnancy and during birth. Although Zika is transferred to the child by the mother during pregnancy or birth, studies do not show that to be the same for breastfeeding. A person can also contract the zika virus from anal, oral, intercourse, or sharing sex toys with an infected person. The CDC has stated that a person can become infected by a person who’s already infected before, during, and after their symptoms have occurred. The transmission however is not a skin to skin contact, direct contact unless it is sexual. Blood …show more content…
virus is by avoiding mosquito bites, wearing protective clothing, proper use of EPA-registered mosquito repellent containing: DEET, IR3535, or Icarian (according to the CDC), and mosquito nets for the people who rest during the day. If a person is caring for someone with the Z. virus they should use precaution with any bodily fluids. They should wash their hands immediately after caring for the infected person. If bodily fluids appear on the clothes of a non-infected person they should immediately remove their clothes and wash them according to the material. Bleaching clothes are not necessary. If bodily fluids are found on any surface, clean and sterilize the area accordingly. Mosquito control and sex education could help raise the awareness of the spread. For infected people who have sex with non-infected people, condoms and dental dams can lower the risk of the disease sexually.
First isolated from a rhesus monkey in Uganda, the Zika virus (ZIK V) did not pose a serious global threat until recent outbreaks in 2007 on Yap Island in Micronesia and the current outbreak which began in 2013 in the French Polynesia. And, although the virus is transmitted via infected mosquitoes, studies indicate that the disease potentially can be transmitted sexually (Musso, D., Roche, C., Robin, E., Nhan, T., Teissier, A., and
Zika virus was discovered by scientists in the Zika rainforest in a remote part of Uganda in 1947, in the serum of an infected rheseus monkey. With five thousand two hundred thirty- four known cases of the infectious virus documented in the United States. There is currently no vaccination for the flu like virus. The chief concern of the healthcare administration is to continue to take preventive measures to prevent contracting the virus. Within the same flavivirus family
By getting the virus from a bite the mosquito must already be infected itself. There are studies currently happening trying to figure out how long exactly does the virus stay inside the semen and vaginal fluids of those who are infected, also being studied is how long it can be passed to their partners. Although the U.S. hasn't seen any cases of the disease being transmitted by blood transfusion it has been seen in other places in the world. An example would be the French Polynesian outbreak, around 2% of those donating blood tested positive for Zika however, in previous outbreaks the virus was also found. Just one case in the United States shows of someone getting ill through a laboratory yet, prior situations show four cases of someone getting the virus in a laboratory
“Zika virus can pass back and forth between people and mosquitoes—most people get Zika from a mosquito bite, but infected people can also pass Zika to mosquitoes that bite them” (Schmidt, 2016).
First, the Zika virus is carried by mosquitos. It can be transmitted by getting bitten by an affected mosquito. For some people symptoms can be felt as brief mild flu-like illness (Brown). The virus has many ways of spreading throughout the world.
In the article, “Local Transmission of Zika Virus is reported in Texas”, it stated that on November 28th, 2016 health officials announced Zika has been reported in Texas. In the United States, the virus has only been in Florida. In Florida, it was believed to be carried by mosquitoes from person to person. But this case in Texas is carried by a women. Medical Investigators are trying to found out if the infection is spreading.
Zika is a new virus that affects affects pregnant women and mainly the babies. the virus comes from a mosquito in Brazil. The mosquito causes the brain and the head of the baby to be smaller the a normal sized head. If the mosquito bites a male it will only cause bloodshot eyes, rashes, pain in the joints, and headaches. The symptoms only last for a week.
Zika is a forest in Uganda where the virus was discovered. Although the first case of Zika was discovered in 1947, the virus has just started spreading to America and parts of Asia this year.
Zika is a disease that presence it’s self in pregnant women. It spreads through mosquitos and can be given to humans through there bite. The disease can also be spread sexually, but symptoms do not show in males. Symptoms of the disease are fever, rash, red eyes, and joint pain. This disease also causes the baby to have birth defects when being born. The birth defects occur in the brain of the baby, causing the brain to be smaller than average.
Sifferlin states, “First discovered in Uganda's Zika forest in 1947” (Sifferlin). With that being said it does not seem as if the government is doing much research into what to do about the spreading virus. Sifferlin states, “Even now, many people who get infected will never know it, and if they start showing signs of infection, such as a rash, red eyes, fever or joint pain, doctors have little to offer other than advice to stay hydrated or take Tylenol as needed” (Sifferlin). Due to the fact that the virus can be spread sexually, if one has visited any place where Zika Virus is present, it is extremely important to get tested to avoid spread of the virus to others. However, the tests take weeks for results and are not covered by most
The Zika virus has shown to be increasingly circulating into a larger portion of the United States. This virus has devastating effects in people of all ages, including unborn children in pregnant women. Therefore, no one is protected from these virus carrying mosquitos. Symptoms including fevers, red eyes, rashes, and joint pain. Although the virus does not kill an infectee directly, infections and other complications will arise from the virus and could lead to fatality.
Zika virus disease, also referred to as Zika, is a disease that people can contract from the Zika virus. The Zika virus first emerged in Uganda in 1947 in rhesus monkeys. Its name comes from the Zika forest located in Uganda (CDC).
Researchers found the Zika virus is a member of the Flaviridae family and is transmitted to humans by, mosquitoes. Although these research results are promising, it is difficult to determine whether this experiment really did ZIKV virus is a members of the Flaviridiae family or different family. Was the experiment of the ZIKV conduct appropriately to all animal? And although this research promising, results for the most flaviuvirus family. Interestingly, the virus was also detected in testicles of infected mice. We have no idea whether these result are applicable to another types of virus. So this article is miss leading and this conclusion does not necessary apply to all virus.
“Zika virus disease (Zika) is a disease caused by the Zika virus, which is spread to people primarily through the bite of an infected Aedes species mosquito” (Centers for Disease Control and Prevention, 2016). Evidence also tie in Zika to sexual transmission from men to their partner. Although there is no currently evidence to sexual transmission from women to their partner. The virus is unusual distress for pregnant women because Zika can be pass on and surpass to relentless birth defect. The World Health Organization has stated the Zika virus an international public health emergency, suggested by rising affect that could produce birth defect.
Dr. Dan Pastula discussed that arboviruses are transmitted by mosquitoes, ticks, or sandflies. Zika has become a well known virus, but it was first identified in Uganda in 1947. It was thought for a long time, that patients are asymptomatic to mildly sick due to Zika virus. Rash, fevers, arthragias, myalgia, headaches, and conjunctivitis are common symptoms. However, Zika traveled across the Pacific and is now in areas that it previously was not. It is now known that Zika can be transmitted through sex and can have more severe disease. AIDP, meningoencephalitis, myelitis, and seizures can be seen in patients with active virus, and congenital abnormailites have been seen.
