Virus Zica is spread to people by the bite of an infect Aedes species mosquito. The most typical symptoms of Zika infection are fever, rash, headache, joint pain, and conjunctivitis (red eyes). About one in five people infect with Zika is sick. The sickness is usually mild with symptoms persisting for several days to a week. Patients usually are not ill enough to go to the hospital, and they rarely die of virus Zica.
1. Virus Zica: Is this a new virus?
No. Epidemics of Zika have been previously report in tropical Africa, Southeast Asia, the Indian subcontinents, and the Pacific Islands. Zika virus will likely continue to spread to new regions. In May 2015, the Pan American Health Organization (PAHO) declare an alert regarding the first Zika virus infection in Brazil. Since then, local transmission has been confirm in many other countries and territories.
Anyone who lives in or travels to a region where the outbreak is ongoing and has not already been infect with Zika virus could contract it from mosquito bites. It is often difficult to determine specific areas where Zika virus transmission is raging since such areas are likely to change over time. Please visit the CDC Travelers’ Health site for the most update information about Zika outbreaks.
2. Virus Zica: How is Zika transmitted?
Zika is mainly spread by the bite of infect Aedes mosquitoes, the same mosquitoes that transmit dengue and chikungunya. These mosquitoes are aggressive biters, and they can bite during day and night. Mosquitoes become infect after they bite a person already had the virus in his blood. Infect mosquitoes can later spread the virus to other healthy people through bites. Sometimes, the virus can be transmit from a pregnant mother to her baby during pregnancy or childbirth.
3. Virus Zica: What can people do to prevent?
Vaccines against Zika are unavailable. The best way to prevent Zika infection is to protect yourself from mosquito bites. Here are some suggestions:
- Wear clothing that can cover as much expose skin as possible, such as long-sleeve shirts, long pants, shoes, hats, gloves, socks, and so on.
- Stay in rooms with air conditioning or with door and window screens to keep mosquitoes outside.
- Apply (EPA)-registered insect repellents since they are all evaluate for safety and effectiveness.
- Reapply insect repellent as direct.
- Do not spray repellent directly on the skin.
- Always follow the product label instructions.
- If you want to use sunscreen at the same time, apply sunscreen before insect repellent.
- If you have a baby or child:
- Cover your baby’s arms and legs with clothing.
- Cover cribs, strollers, and baby carriers with bed nets.
- Never use insect repellent on babies younger than two months of age.
- Never spray insect repellent into a child’s eyes, hands, mouth, and cut or irritate skin.
- Buy permethrin-treat items, clothing, and gear.
- Follow the product instructions carefully.
- Never use permethrin products directly on the skin.
- Sleep under a bed net if you are outside and are not able to protect yourself from mosquito bites.
4. Virus Zica: What is the treatment?
- Get plenty of rest.
- Drink much fluid to prevent dehydration.
- Take medicine containing acetaminophen to reduce pain and fever.
- Never take aspirin or other non-steroidal anti-inflammatory drugs. They worsen internal bleeding.
- Talk to your healthcare provider if you are taking additional drugs for another medical condition.
During the incubation period, Zika virus can be found in the blood of patients. It is pass from an infected person to another one through mosquito bites. An infect mosquito can afterward spread the virus to other people. As a result, the priority is to avoid mosquito bites during the first week of sickness.
See your healthcare provider if you develop the symptoms as mention above within two weeks after traveling to a place where Zika virus is raging. Be sure to let your doctor know about your travel history. Once a person has been infect, he is likely to be protect from future infections.
5. Virus Zica: infection in pregnant women cause defects?
There is evidence of a severe birth defect of the brain and other poor pregnancy outcomes in newborns whose mothers were infect with Zika virus while pregnant. One of the most typical ones is microcephaly, a condition wherein a baby’s head is unusually small when compare to heads of those of the same age and gender.
Until more is known about the connection between Zika and these outcomes, both pregnant women and those who are trying to become pregnant are recommend to consider postponing travel to any area where Zika virus is circulating. If the trip is unavoidable, it is compulsory for them talk to their doctor and strictly follow steps to restrict mosquito bites.
6. Virus Zica: Does infection trigger Guillain-Barré syndrome (GBS)?
Guillain-Barré syndrome (GBS) is a rare disorder in which a person’s immune system itself damages the nerve cells, leading to muscle weakness and sometimes, paralysis. Its symptoms can last a few weeks to several months. While most patients fully recover from GBS, some may suffer permanent damage and in rare instances, people have died.
Little is known if Zika virus infection triggers GBS. It is hard to determine whether any particular germ causes GBS. An increase number of people affect with GBS is being report by the Brazil Ministry of Health (MOH). At the present, CDC is cooperating with the Brazil MOH to determine whether contracting Zika makes it more likely for you to have GBS.
7. Virus Zica: What is WHO doing?
WHO has been aware of Zika and has been preparing for its potential introduction into new parts of the world. Laboratories in many nations have been train to identify dengue, chikungunya, and Zika virus.
WHO is working with international health partners and state health officials to:
- alert healthcare providers and the populace about Zika;
- update notices and other travel-relate guidance;
- support laboratories with diagnostic tests; and
- detect and report cases, which helps to prevent further spread.
The outbreak of virus Zica all over the world demonstrates the risks pose by it and other exotic viruses. WHO’s health security are designing plans to monitor the disease effectively, equip diagnostic laboratories, and provide mosquito control programs around the world.
