Chikungunya Disease in Angola

If you've recently moved to Angola or are planning to, it's essential to be aware of Chikungunya Disease, spread by mosquitoes. This illness is frequently confused with the Zika Virus, and many suffer from persistent joint pain after recovering from the initial symptoms.

Chikungunya virus is a mosquito-borne disease that has been a significant health concern in several parts of the world, including Angola. This article aims to provide comprehensive information about the Chikungunya virus in Angola, its symptoms, prevalence, prevention methods, and its impact on different age groups and those with compromised immune systems.

What is Chikungunya Disease?

Chikungunya is a viral disease transmitted to humans by infected mosquitoes, primarily Aedes aegypti and Aedes albopictus. The symptoms usually appear between 4 and 8 days after the mosquito bite and can include high fever, severe joint pain, muscle pain, headache, nausea, fatigue, and rash. The joint pain is often debilitating and can last for weeks or months, and in some cases, years. Most patients recover fully, but in some cases, the disease can lead to long-term complications such as persistent joint pain, eye, neurological and heart complications. There is no specific antiviral drug treatment for Chikungunya; treatment is directed primarily at relieving the symptoms.

Where is Chikungunya Most Prevalent in Angola?

Chikungunya virus was first detected in Angola in 2019. The disease is most prevalent in urban and semi-urban areas where the mosquito vectors thrive. The capital city of Luanda has been particularly affected due to its high population density and the presence of numerous breeding sites for mosquitoes. However, the disease has also been reported in other provinces of the country.

How do Expats in Angola Prevent Mosquito Bites?

Preventing mosquito bites is the most effective way to avoid Chikungunya and other mosquito-borne diseases. Expats in Angola are advised to use insect repellent, wear long-sleeved shirts and long pants, and ensure their accommodations are mosquito-proof by using window and door screens or air conditioning. It is also recommended to empty, cover, or treat any items that hold water, such as buckets, flower pots, or tires, to eliminate mosquito breeding sites. In addition, expats should consider getting vaccinated if a vaccine is available.

What if I get Chikungunya Virus in Angola?

If you get infected with the Chikungunya virus in Angola, it is important to seek medical attention immediately. While there is no specific treatment for the disease, doctors can help manage symptoms. Rest and hydration are crucial, and over-the-counter pain relievers can help with fever and joint pain. It is also important to avoid mosquito bites to prevent further spread of the virus.

Is Chikungunya Virus Contagious?

Chikungunya virus is not directly contagious from person to person. The virus is transmitted to humans through the bite of an infected mosquito. However, a mosquito can pick up the virus from an infected person and then spread it to other people. Therefore, an infected person should avoid mosquito bites during the first week of illness to prevent further transmission.

Is Chikungunya Virus More Dangerous for Children, Elderly or Immune-Compromised?

While Chikungunya virus can infect individuals of all ages, the disease tends to be more severe in infants, the elderly, and those with underlying health conditions. These individuals are more likely to develop complications and have a higher risk of severe disease and death. Therefore, it is particularly important for these high-risk groups to take precautions to prevent mosquito bites and seek medical attention promptly if they develop symptoms of Chikungunya.
