Understanding A90 Dengue (Classical Dengue Fever)

What is A90 Dengue?

A90 Dengue, also known as classical dengue fever, is a viral illness transmitted by mosquitoes. It is caused by the dengue virus, which belongs to the Flaviviridae family. The A90 Dengue virus is primarily transmitted to humans through the bite of infected Aedes mosquitoes, particularly Aedes aegypti and Aedes albopictus. These mosquitoes are prevalent in tropical and subtropical regions, making A90 Dengue a significant public health concern in these areas.

The A90 Dengue virus has four distinct serotypes, known as DENV-1, DENV-2, DENV-3, and DENV-4. Infection with one serotype does not provide immunity to the others, and individuals can be infected with multiple serotypes over their lifetime. This increases the risk of severe dengue, also known as dengue hemorrhagic fever, which is a potentially life-threatening complication.

The symptoms of A90 Dengue typically begin 4-10 days after being bitten by an infected mosquito. The most common symptoms include:

• High fever
• Severe headache
• Joint and muscle pain
• Nausea and vomiting
• Rash

In some cases, A90 Dengue can progress to severe dengue, characterized by severe abdominal pain, persistent vomiting, bleeding gums, fatigue, restlessness, and difficulty breathing. Severe dengue requires immediate medical attention and hospitalization.

Diagnosing A90 Dengue involves blood tests to detect the presence of the virus or antibodies produced in response to the infection. Early diagnosis is crucial for proper management and to prevent complications. Currently, there is no specific antiviral treatment for A90 Dengue, and management focuses on relieving symptoms and maintaining hydration. Pain relievers such as acetaminophen are commonly used to reduce fever and relieve pain, while intravenous fluids may be necessary to prevent dehydration.

Prevention of A90 Dengue is centered around mosquito control and public health interventions. This includes eliminating mosquito breeding sites, using insect repellent, wearing protective clothing, and using mosquito nets. Vaccination against A90 Dengue is also available in some regions, offering protection against all four serotypes of the virus. Vaccination efforts are particularly important in areas with high dengue transmission rates.

According to the World Health Organization (WHO), an estimated 3.9 billion people in 128 countries are at risk of A90 Dengue infection. The incidence of A90 Dengue has increased dramatically in recent decades, with a 30-fold increase in global incidence over the past 50 years. This upward trend is attributed to various factors, including urbanization, population growth, and climate change.

Complications of A90 Dengue can be severe and potentially life-threatening. These include dengue hemorrhagic fever, dengue shock syndrome, and organ damage. Severe bleeding, known as dengue hemorrhage, can occur in severe cases and requires immediate medical intervention. Organ damage, particularly liver and heart damage, can also occur in severe dengue cases.

In conclusion, A90 Dengue, or classical dengue fever, is a significant global health concern. It is essential to raise awareness about A90 Dengue, improve mosquito control measures, and promote vaccination to reduce the burden of this disease. Public health efforts, combined with individual protective measures, are crucial in preventing the spread of A90 Dengue and mitigating its impact on affected communities.
