As Dhaka already grapples with a dengue outbreak, health authorities are warning about the emergence of Zika virus cases in the capital. Both dengue and Zika are transmitted by Aedes mosquitoes, which are prevalent in Dhaka.
Here is everything you need to know about Zika virus.
What is Zika virus?
Zika virus is a mosquito-borne illness that has made headlines globally due to its rapid spread in recent years. It is primarily transmitted by the Aedes mosquito, which is also responsible for spreading dengue and chikungunya.
Although Zika is generally mild for most people, its association with birth defects, especially microcephaly in babies born to infected mothers, makes it a public health concern, particularly for pregnant women.
How Zika virus spreads
Zika virus can spread in several ways, making it crucial to take comprehensive precautions. The primary method of transmission is through the bite of an infected Aedes mosquito.
These mosquitoes are most active during early mornings and evenings. Other ways Zika can spread include sexual transmission, pregnancy, and blood transfusion.
Symptoms of Zika virus
According to the Institute of Epidemiology, Disease Control, and Research (IEDCR), around 80% of people infected with Zika may not show any symptoms. For those who do, symptoms usually develop within 3 to 12 days after exposure and last for about 2 to 7 days.
The most common symptoms include low-grade fever (37.2°C), red rash on the skin, headache, red eyes (conjunctivitis), muscle pain and joint pain
While the illness typically resolves on its own, the symptoms can be uncomfortable, and it is important to stay hydrated and rest.
Preventive measures
To reduce the risk of contracting Zika, it’s important to take proactive steps. One can avoid mosquito bites by wearing long-sleeved clothing, applying mosquito repellent, and using mosquito nets, especially during early morning and evening hours.
Pregnant women should avoid traveling to Zika-affected areas or take strict precautions to prevent mosquito exposure. Additionally, individuals who have traveled to such regions should use condoms for at least 6 months to prevent sexual transmission.
Cure for Zika virus
Currently, there is no specific cure for Zika virus, and treatment is primarily supportive. The Institute of Epidemiology, Disease Control, and Research (IEDCR) recommends rest, staying well-hydrated, and taking paracetamol for fever and pain, but only under the guidance of a doctor.
If symptoms worsen, individuals should seek immediate medical attention. Since there is no vaccine for Zika, prevention through protective measures is crucial.
Awareness, vigilance, and precautionary actions such as minimizing mosquito exposure and practicing safe sexual behaviors are essential in reducing the risk of infection.
