Since last year, the Zika virus has been making headlines across the country, and while its effects aren't as widespread as it was once feared they might be, it's still important to take precautions about the virus when visiting warmer climates. As autumn arrives, mosquito populations are bound to decrease, though in some parts of North America, the insects will never go away for long. Here's what you need to know about Zika as the season changes:
Pesticide use in Florida
According to the U.S. Centers for Disease Control and Prevention, there have been 43 confirmed cases of locally acquired Zika virus. Thus far, Florida is the only state with locally acquired cases, which means those visiting the state should take extra precautions to avoid contact with mosquitoes. Most cases of Zika in Florida have come from the area around Miami beach. In response, the local government has been employing an aerial campaign of pesticides to reduce populations of potentially infected mosquitoes.
Travelers to Miami have been encouraged to wear long sleeves and pants to limit skin exposure. Likewise, it's important to wear insect repellant with DEET.
Symptoms of Zika virus
The symptoms of Zika virus are similar to those of other common viruses, meaning that those infected with Zika may not even know they have it. According to the CDC, common symptoms include red eyes, fever, joint pain, rashes and headaches. Symptoms typically last for a week before dissipating and rarely require medical treatment. If you're visiting an area known to have Zika infected mosquitoes and you experience these symptoms, it's still a good idea to visit a doctor.
Zika transmission
The main way Zika is transmitted to humans is via mosquito bite. Thus far, very few species of North American mosquitoes carry Zika. Those that do are so far confined to southern Florida and the Caribbean. The World Health Organization reported that Zika virus may be transmitted via sexual contact and it's possible that blood transfusions may also pose a risk.
Zika virus and infants
While the virus doesn't pose much threat to healthy adults, pregnant women and their children may be at a great risk of experiencing health problems. Unborn children whose mothers contract the virus are at an increased risk of brain damage, including a condition known as microcephaly, a condition that causes the size of the head to be much smaller than normal. Instances of microcephaly have been documented in South American countries such as Brazil, reported the New York Times.
If you live in a region with cold autumn and winter weather, chances are you won't have to worry much about the Zika Virus. However, precautions should be taken when traveling to areas with known cases of the virus. Pregnant women should be especially wary of traveling to those regions and should even consider delaying any travel plans until after the birth of their child.
