Zika virus was first discover in 1947, but for many years, only sporadic cases were report in Africa and Southeast Asia. In 2007, the first outbreak of Zika virus disease happen in the Pacific. Zika virus disease has globally spread owing to the expansion of environments where mosquitoes live and breed, facilitate by urbanization and globalization. Virus Zica Infection appears in tropical areas and is known to circulate in Africa, the Americas, Southeast Asia, and the Western Pacific.
1. Virus Zica Infection: How do people contract?
People catch Zika virus through being bitten by an infected Aedes mosquito – the same mosquito that transmits dengue, chikungunya, and yellow fever.
2. Virus Zica Infection: Where can the Aedes mosquito survive?
There are two types of Aedes mosquito spreading the Zika virus. Quite often, Zika is transmit by the Aedes aegypti mosquito in the tropics and subtropics. This mosquito does not survive in cool climate temperatures. The other type is the Aedes albopictus mosquito, which can hibernate and survive in cool regions.
3. Virus Zica Infection: Can the Aedes mosquito fly?
This mosquito is a weak flyer which cannot fly more than 400 meters. However, it may be accidentally transported by humans from one area to another (e.g. in the back of the car). In theory, if it can adapt itself to the temperature climate of the destination, it might be capable of reproducing itself and introduce Zika virus to the new place.
4. Virus Zica Infection: What are the symptoms?
In most cases, Zika virus causes mild illness. Symptoms appear several days after a person is bitten by an infect female mosquito. For that reason most patients with Zika virus disease will represent a slight fever and rash. Others might exhibit red eyes, muscle and joint pain, and conjunctivitis. The symptoms usually finish in two to seven days, meaning that the immune system has clear the virus from the blood. If you were sick on your last day in the infect area and experience no symptoms, for about 20 days, you might theoretically pass the virus to a mosquito back home.
5. Virus Zica Infection: What are the potential complications?
Since no significant outbreaks of Zika virus were document before 2007, little is currently determine regarding the complications of the sickness. During the first outbreak of Zika from 2013 to 2014 in French Polynesia, national health authorities report an abnormal increase in Guillain-Barré syndrome. A similar observation of explode Guillain-Barré syndrome was also made in 2015 during the first Zika virus outbreak in Brazil.
Also in 2015, local health authorities in Brazil observe an increase of microcephaly in newborn babies. Agencies are now investigating the possible link between Zika virus and microcephaly, above and beyond other potential causes. More investigation and research are necessary before we are able to understand better any possible connection.
Guillain-Barré syndrome is a condition wherein the body’s immune system attacks parts of the nervous system. It might be caused by a handful of viruses and can affect people of any age. What triggers the syndrome is not known yet. The primary symptoms involve muscular weakness and tingling in arms and legs. Severe complications may occur if the respiratory muscles are influence, requiring hospitalization. Most people with Guillain-Barré syndrome will recover while some may continue to experience consequences such as weakness.
6. Virus Zica Infection: What is microcephaly?
It is a rare condition in which a baby is born with an unusually small head. This is due to an abnormal brain development of the baby in the womb or during infancy. Children with microcephaly often have difficulties with their brain development when they grow older. Microcephaly can be cause by a plenty of environmental and genetic factors e.g. Downs syndrome; exposure to drugs, alcohol or other toxins in the womb; and rubella infection during pregnancy.
7. Virus Zica Infection: Should pregnant women be worried?
Health authorities are presently investigating a potential connection between Zika virus and microcephaly during pregnancy. In a word, women who are pregnant or contemplating pregnancy should take extra care to protect themselves against mosquito bites. If you are pregnant and living in an infecte area, consult your doctor for testing and close monitoring.
8. Virus Zica Infection: How diagnosed and treated?
Diagnosis of Zika virus disease is based on one’s symptoms and recent history (e.g. mosquito bites, or traveling to an area where Zika virus is report). Doctors may order blood tests to confirm the diagnosis. The C.D.C. does not recommend a specific antiviral medication for those infect with the Zika virus. The disease can be treat with only rest, nourishment and plenty of fluid, pain and fever medicines, and other supportive care. Symptoms are mild and thus in most cases, patients spontaneously feel better within two weeks. If symptoms worsen, it is time to seek medical care.
9. Virus Zica Infection: Is there a vaccine?
At this juncture, no cure or vaccine is available for the disease itself. Efforts to create one have just begun, and producing and testing a vaccine commonly takes years and costs millions of dollars. Since it is impossible to fully prevent mosquito bites, the C.D.C. has advise people to avoid going to regions where Zika is known to be present and has advise pregnant women to consult doctors before their trips.
10. Virus Zica Infection: What can I do to protect myself?
The best way to prevent virus Zica is to avoid mosquito bites. This also helps you to prevent diseases that are transmit by Aedes mosquitoes such as dengue, chikungunya, West Nile fever, and yellow fever. It is advisable to use insect repellent at all times; wear light-color clothes that cover as many parts of the body as possible; use barriers such as screens or close doors and windows; stay in screen or air-condition rooms if possible; sleep under mosquito nets. For that reason it is also crucial to clean, empty, or cover containers that can accumulate even small amounts of water such as cans, bottles, buckets, flower pots or tires. Make sure you remove places where mosquitoes can breed. Anybody returning from areas in which the virus is circulating is advise to use condoms for 28 days to be sure that they cannot infect their partners.
