Debunking Dengue Myths: 5 Important Facts We Need To Know About Dengue

Here are some myths about dengue that doctors have debunked!

As the rainy season grips the Philippines, health concerns resurface, with dengue fever taking center stage. The Department of Health (DOH) has reported a worrying 15% increase in dengue cases compared to the same period last year, a trend that underscores the pressing need for awareness and action. Dengue, recognized by the World Health Organization (WHO) as the fastest-spreading mosquito-borne illness globally, affects approximately 400 million people annually and is prevalent in over 100 countries. Despite its widespread impact, many myths and misconceptions continue to cloud public understanding, hindering effective prevention and protection.

Here, we will debunk five common dengue myths and provide essential facts that everyone should know. Moreover, we hope to offer insights into the nature of dengue and why dispelling these myths is crucial for public health.

Myth #1: Dengue Fever Cannot Be Contracted More Than Once

One of the most dangerous misconceptions about dengue is the belief that once you’ve had it, you’re immune for life. In reality, the dengue virus (DENV) has four distinct serotypes. Immunity developed after infection with one serotype does not protect against the other three. This means that not only can you contract dengue more than once, but subsequent infections are often more severe. The risk of severe dengue, also known as dengue hemorrhagic fever, increases with each new serotype exposure.

Understanding the different serotypes of dengue is crucial. Each serotype can cause the same symptoms, but the body’s immune response to a second or third serotype can lead to more severe outcomes. This is known as antibody-dependent enhancement (ADE), where the immune system’s response to a previously encountered serotype can actually worsen the disease upon exposure to a new serotype. This highlights the importance of continuous preventive measures even after recovering from a dengue infection.

Myth #2: Dengue Is Contagious

Dengue is not contagious in the way diseases like the flu or COVID-19 are. It cannot be spread from person to person through direct contact, respiratory droplets, or physical touch. Dengue is transmitted exclusively through the bites of infected female Aedes mosquitoes, primarily the Aedes aegypti species. These mosquitoes become carriers of the virus after biting an infected person, and they can then spread the virus to others through subsequent bites.

The misconception that dengue can be spread through human contact can lead to unnecessary fear and stigma towards those suffering from the illness. The real focus should be on mosquito control and personal protection. Eliminating mosquito breeding sites, using mosquito repellents, and installing screens on windows and doors are some of the most effective ways to prevent the spread of dengue.

Myth #3: An Infected Mosquito Only Breeds in Dirty, Stagnant Water

Aedes mosquitoes are not picky about the cleanliness of their breeding sites. They can lay their eggs in any stagnant water, whether it’s clean or dirty. Common breeding sites include basins, pots, jars, rain gutters, and even bottle caps or plastic containers. The key factor is the presence of standing water, which provides an ideal environment for mosquito larvae to develop.

This myth underscores the need for vigilance in maintaining clean surroundings. Regularly emptying and cleaning potential breeding sites, no matter how small, can significantly reduce the mosquito population in your area. It’s a simple yet effective strategy that communities can adopt to prevent dengue outbreaks.

Myth #4: Dengue Fever Is Only a Risk During the Rainy Season

While it’s true that the rainy season can create more breeding sites for mosquitoes, dengue fever is a risk year-round. Aedes mosquitoes are attracted to carbon dioxide and heat, both of which are present in any season. Therefore, even during the dry months, mosquitoes can find places to breed and continue spreading the virus.

This myth can lead to complacency during the dry season, causing people to let their guard down when it comes to mosquito control. It’s essential to maintain preventive measures throughout the year, not just when it’s raining. Communities should stay proactive by continuously monitoring and eliminating potential breeding sites, regardless of the season.

Myth #5: The Body Can Naturally Recover From Dengue Fever Without Medical Intervention

Fact: Dengue fever often presents as a week-long episode of severe headache, vomiting, and muscle pain. While many people can recover with rest and hydration, the disease can escalate quickly and unpredictably, leading to severe dengue, which requires immediate medical attention. Severe dengue can cause complications such as bleeding, organ impairment, and even death if not treated promptly.

The assumption that dengue is a mild illness that can be managed at home is dangerous. The variability in the disease’s progression makes it critical to seek medical advice as soon as symptoms appear. Early detection and proper medical care can significantly reduce the risk of severe complications and improve outcomes for those affected by dengue.

The Broader Impact of Dengue and the Role of Public Health

Dengue’s impact goes beyond individual health, affecting families, communities, and economies. The financial burden of treating dengue can be significant, especially in cases requiring hospitalization. This is where insurance products like PRUDengue MedCare and PRUDengue MedCare Pro come into play, offering financial assistance upon diagnosis and helping families manage the costs associated with the disease.

Pru Life UK’s proactive approach in providing coverage against dengue and other infectious diseases, such as Typhoid, Measles, and Malaria, highlights the importance of being prepared for health risks. Their PRUMedCare – Select Infectious Diseases product is designed to offer broader coverage, ensuring that Filipino families have the support they need during unforeseen events.

Debunking dengue myths is not just about correcting misinformation—it’s about empowering people with the knowledge they need to protect themselves and their communities. As dengue continues to spread globally, with the Philippines being no exception, accurate information and proactive measures are our best defenses against this potentially deadly disease.

Allow this to be a reminder that dengue is a complex illness requiring a comprehensive approach to prevention and treatment. From understanding the nature of the virus and its transmission to recognizing the importance of year-round vigilance, these insights can help individuals and communities stay safe. Only by staying informed and proactive can we truly combat dengue and protect the health of our nation.
