Belize's Battle Against Zika: Understanding The Risks And Realities

Belize is a country with a risk of Zika virus transmission. The Zika virus is mainly spread through mosquito bites, and the mosquito responsible most commonly bites during daylight hours and is common in towns and cities. While the illness is usually mild, infection during pregnancy may lead to babies being born with birth defects. There is currently no vaccine available against the Zika virus. As such, it is recommended that travellers to Belize practice strict mosquito bite avoidance at all times.

Preventing Zika: protective measures

Belize is a tropical country with a risk of Zika virus transmission. The Zika virus is spread through the bite of an infected Aedes aegypti mosquito, which is most active during the daytime and is commonly found in towns and cities. The illness is usually mild, but it can cause serious birth defects if a pregnant person is infected. Currently, there is no vaccine available against the Zika virus. Therefore, it is important to take protective measures to prevent mosquito bites and sexual transmission. Here are some preventive measures to reduce the risk of Zika:

• Use mosquito repellent: Apply Environmental Protection Agency (EPA)-registered insect repellent on exposed skin and clothing. Follow the instructions on the product label, and reapply as directed.
• Wear protective clothing: Wear long-sleeved shirts, long pants, and light-coloured clothing when possible. Treat clothing and gear with permethrin or purchase pre-treated items.
• Stay in screened or air-conditioned rooms: Keep windows and doors closed, and use air conditioning to keep mosquitoes out. Sleep under a mosquito net if you are unable to protect yourself from mosquito bites.
• Eliminate mosquito breeding sites: Remove standing water and take steps to control mosquitoes inside and outside your home.
• Practise safe sex: Use condoms consistently and correctly during vaginal, anal, and oral sex. Avoid sex or use condoms for at least six months after returning from a Zika-affected area, especially if you are pregnant or planning a pregnancy.
• Prevent bug bites: Cover exposed skin, use insect repellent with at least 20% DEET, and stay in screened or air-conditioned rooms.
• Food and water safety: Prioritize food safety by consuming fully cooked dishes, avoiding raw seafood, and choosing restaurants with good hygiene practices. Drink only bottled water, and be cautious with ice and alcohol.
• Prevent travellers' diarrhea: Maintain vigilant hand hygiene and avoid unsanitary street food.
• Seek medical advice: Consult a healthcare professional before travelling to Zika-affected areas, especially if you are pregnant or planning a pregnancy.

Zika symptoms and treatment

Zika is a mosquito-borne virus, similar to dengue fever, yellow fever and West Nile virus. The infection is associated with a birth defect called microcephaly, which can affect babies born to people who become infected with Zika while pregnant.

Most people with Zika exhibit mild symptoms or have no symptoms at all. Symptoms include:

• Zika rash: red spots that may be flat, raised or both
• Arthralgia (joint pain)
• Conjunctivitis (red, inflamed eyes)
• Fever
• Joint and muscle aches
• Pain behind the eyes
• Headache

Symptoms usually last for several days to a week and clear up on their own. Hospitalisation is rare.

Zika can be diagnosed through a blood or urine test. There is currently no vaccine or antiviral treatment for Zika. Treatment addresses symptoms, with doctors recommending:

• Drinking plenty of fluids
• Taking acetaminophen for fever

Pregnant women who have travelled to a location where Zika cases have been reported should contact their doctor as soon as possible. They will continue to undergo regular monitoring to watch for fetal abnormalities.

The best way to protect yourself from Zika is to limit your exposure by avoiding travel to countries where Zika outbreaks are happening. If you must travel to an affected area, take precautions to prevent mosquito bites:

• Wear long-sleeved shirts and long pants to limit skin exposure
• Stay indoors in screened-in or air-conditioned rooms as much as possible
• Use mosquito netting
• Use Environmental Protection Agency-approved bug spray with DEET or picardin, or wear permethrin-infused clothing

Zika and pregnancy

Zika poses serious risks to pregnant women and their babies. If a pregnant woman contracts Zika, the virus can be passed to the baby, causing a birth defect called microcephaly, as well as other brain problems and severe developmental issues. Miscarriages and stillbirths have also been linked to Zika infection during pregnancy.

Pregnant women or those trying to conceive should avoid travel to Zika-affected areas unless absolutely necessary. If travel is essential, it is vital to take strict mosquito bite prevention measures, as mosquitoes are the most common vector for Zika transmission. This includes using insect repellent, wearing long-sleeved clothing and staying in air-conditioned or well-screened rooms.

Pregnant women should also use barrier methods of contraception during and after travel to Zika-affected areas, even if no symptoms of Zika infection are present. If a male partner has travelled to a Zika-affected area, it is recommended to abstain from sex or use barrier contraception for three months after his return. If a female partner has travelled to a Zika-affected area, the same precautions should be taken for two months after her return.

If you are pregnant and think you may have been exposed to Zika, seek immediate medical advice. There is currently no vaccine available to prevent Zika, so prevention is critical.

Zika and sexual transmission

Zika is a viral infection transmitted by Aedes mosquitoes. It poses a risk of birth defects in newborn babies and can also be transmitted sexually. The virus can be passed on by both men and women, even when they don't exhibit any symptoms. It is the only arbovirus known to be transmitted sexually.

Zika can be transmitted through vaginal, anal, and oral sex, as well as the sharing of sex toys. It has been detected in semen, vaginal fluids, saliva, urine, and breast milk. However, there is no evidence that it can be transmitted through saliva during deep kissing. The use of condoms or abstinence is recommended to prevent the spread of the virus.

In the case of pregnant women or those planning to become pregnant, it is advised to use condoms or abstain from sex for the entire pregnancy if there is a risk of Zika exposure. For couples where only one partner has travelled to a Zika-risk area, it is recommended to use condoms or abstain from sex for at least 2-3 months after their return, depending on the partner's gender. If both partners have travelled, they should consider the same precautions for at least 3 months.

The longer precautionary period for males is because Zika can persist in semen longer than in other body fluids. The virus has been detected in semen for more than 180 days after infection, although most reports indicate shorter intervals for potential sexual transmission.

To prevent sexual transmission of Zika, it is important to follow the advice of healthcare providers and take necessary precautions, especially when travelling to or living in areas with a risk of Zika transmission.

Zika and travel insurance

Belize is a country with a risk of Zika virus transmission. The Zika virus is mainly spread through mosquito bites, and the illness is usually mild. However, infection during pregnancy may lead to babies being born with birth defects. There is currently no vaccine available against the Zika virus.

If you are planning to travel to Belize, it is important to consider travel insurance that covers Zika-related risks. Here are some key points about Zika and travel insurance:

• Mosquito Bite Prevention: The Zika virus is primarily transmitted through mosquito bites. To reduce your risk of infection, it is important to take measures to avoid mosquito bites. This includes using insect repellent, wearing protective clothing, and using mosquito nets while sleeping. These measures will help reduce the chances of contracting the Zika virus.
