Can You Get Dengue More Than Once?
Many people wonder about this, especially if they have already experienced the illness. Dengue is caused by the dengue virus, which has four different types, and getting infected with one type usually gives your body immunity only to that type. This means that even after recovering from dengue, it is still possible to get infected again if a mosquito carrying a different type of the virus bites you. In fact, a second infection can sometimes be more severe than the first because the body’s immune response may overreact, leading to more serious symptoms.
In some cases, a second dengue infection can be more severe than the first. This happens because the body’s immune system may overreact when it encounters a new type of the virus, leading to more serious symptoms such as intense fever, severe pain, or bleeding. While most dengue cases are mild, repeated infections can increase the risk of complications, making it important to always take precautions and be aware of early warning signs.
Because there is no guaranteed cure that prevents another infection, prevention remains the best defense. Effective measures include controlling mosquito breeding sites, using mosquito repellent, wearing protective clothing, and keeping surroundings clean. Vaccination may also be recommended in certain areas depending on local health guidelines. By practicing these preventive steps and seeking early medical advice when symptoms appear, individuals and communities can reduce the risk of repeated dengue infections and help protect themselves from severe illness and complications

What is Dengue?
Why does dengue spread so quickly during the rainy season? How can a tiny mosquito bite turn into a serious illness? Dengue is a viral disease caused by the dengue virus and spread through the bite of infected mosquitoes, particularly the Aedes aegypti. It is common in tropical countries like the Philippines, where warm and wet conditions allow mosquitoes to thrive.
Is Dengue Contagious (Nakakahawa)?
Can you catch it just by being near someone who has it? Many people wonder about this, but the truth is, dengue does not spread directly from person to person. It is a viral disease transmitted only through the bite of an infected mosquito, especially the Aedes aegypti, which is common in tropical countries like the Philippines.
