Dengue Virus in Ghana

By Betsy Burlingame

Summary: The Aedes mosquito, known for spreading the dengue virus, is found in Ghana. Being aware of dengue symptoms and taking steps to minimize mosquito bites are crucial for your health and safety in this area.

Dengue virus, a mosquito-borne disease, poses a significant public health challenge in tropical and subtropical regions around the world, including Ghana. Characterized by high fever, severe headache, pain behind the eyes, joint and muscle pain, rash, and mild bleeding, dengue can range from mild to severe. The latter, known as severe dengue or dengue hemorrhagic fever, can be life-threatening. With the global incidence of dengue growing dramatically in recent decades, understanding the disease's presence in Ghana, its symptoms, prevention methods, and treatment options is crucial for both residents and expatriates living in or traveling to the region.

What is Dengue Disease?

Dengue disease is caused by the dengue virus, which is transmitted to humans through the bites of infected Aedes mosquitoes, primarily Aedes aegypti. There are four dengue virus serotypes, meaning that it is possible to be infected four times. Symptoms typically begin three to fourteen days after infection and can include a sudden high fever, severe headaches, pain behind the eyes, joint and muscle pain, fatigue, nausea, vomiting, skin rash, which appears two to five days after the onset of fever, and mild bleeding (such as nosebleed, bleeding gums, or easy bruising). While most people recover within a week or two, severe dengue can develop after the initial symptoms and result in severe abdominal pain, persistent vomiting, rapid breathing, bleeding gums, fatigue, restlessness, and blood in vomit. The illness can last up to 10 days, but complete recovery can take as long as a month. Occasionally, the disease develops into severe dengue, which can be fatal if not properly treated.

Where is Dengue Most Prevalent in Ghana?

Dengue fever is not uniformly distributed across Ghana. It is most prevalent in urban and semi-urban areas where the Aedes mosquitoes thrive, particularly in regions with stagnant water that serves as breeding grounds for the mosquitoes. The Greater Accra Region, being densely populated and urbanized, has reported cases of dengue. Other areas with reported cases include the Central and Ashanti Regions. However, the distribution and prevalence can change with environmental factors, urbanization, and human movement, making it important for ongoing surveillance and reporting.

How do Expats in Ghana Prevent Mosquito Bites?

Expatriates in Ghana can take several precautions to prevent mosquito bites and reduce the risk of contracting dengue virus. These include using mosquito repellent containing DEET, picaridin, IR3535, or oil of lemon eucalyptus on exposed skin and clothing. Wearing long-sleeved shirts and long pants, especially during the early morning and late afternoon when mosquitoes are most active, is also advisable. Expats should ensure that living accommodations are fitted with window and door screens to keep mosquitoes out, and use mosquito nets while sleeping, particularly if staying in areas with a high risk of mosquito-borne diseases. Eliminating standing water around living areas to disrupt the breeding cycle of mosquitoes is another crucial preventive measure.

What if I Get Dengue Virus in Ghana?

If you suspect you have contracted dengue virus in Ghana, it is essential to seek medical attention immediately. There is no specific treatment for dengue fever, but early detection and access to proper medical care lowers fatality rates significantly. Treatment is primarily supportive and includes hydration, pain relievers like acetaminophen, and rest. Aspirin and nonsteroidal anti-inflammatory drugs (NSAIDs) should be avoided as they can increase the risk of bleeding. In the case of severe dengue, hospitalization may be required to manage potential complications, such as administering intravenous fluids and blood transfusion if necessary.

Is Dengue Virus Contagious?

Dengue virus is not contagious and cannot spread directly from person to person. Transmission requires a mosquito as a vector. An Aedes mosquito becomes infected when it bites a person with dengue virus in their blood. It can then transmit the virus to other people through bites. This means that while an individual cannot catch dengue from another person, they can become part of the transmission cycle if they are bitten by an infected mosquito.

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

Dengue virus can be more dangerous for certain populations, such as children, the elderly, or those with compromised immune systems. Children and the elderly may have a higher risk of developing severe dengue, which can lead to serious complications and even death. Similarly, individuals with weakened immune systems or with pre-existing conditions such as diabetes or asthma may be more susceptible to severe dengue symptoms. It is crucial for these high-risk groups to take extra precautions to avoid mosquito bites and to seek medical care promptly if symptoms of dengue are present.

In conclusion, dengue virus is a growing concern in Ghana, particularly in urban and semi-urban areas. Understanding the disease, its symptoms, and the importance of prevention can help mitigate the risks associated with this mosquito-borne illness. Expatriates and residents alike should take proactive measures to protect themselves from mosquito bites and seek medical attention if they exhibit symptoms of dengue fever. With no vaccine widely available for dengue in Ghana, prevention remains the most effective strategy against this potentially life-threatening disease.
