DengueDengue, also called breakbone fever, is a viral infection that is transmitted from mosquitoes to people. It is most common in tropical and subtropical climates. According to experts, it can be contracted through the bite of a mosquito carrying one of four types of dengue viruses, known as DENV. It is transmitted by the Aedes aegypti mosquito, which also carries the Zika and chikungunya viruses. While dengue is not contagious from person to person, it can be transmitted from a pregnant woman to her child.
There is no treatment for dengue except supportive measures such as getting plenty of rest and drinking fluids. Therefore, it is essential to get tested in time.

When should you get tested for dengue?
Dengue can become serious if left untreated. If you develop signs and symptoms such as high fever, rash, and joint pain, get tested for dengue without delay. Molecular testing for dengue virus (PCR), antibody tests, IgM and IgG, complete blood count, and basic metabolic panel are some of the tests you will be asked to undergo to confirm the diagnosis of dengue. It is essential to start treatment immediately once you notice the symptoms and the diagnosis is confirmed.
Symptoms to watch out for
Symptoms of dengue fever include fever over 40°C (104°F), low platelet count, low blood pressure, severe eye pain, headaches, joint and muscle pain, nausea and vomiting, rash, chills, fluid buildup such as ascites, swollen glands, extreme thirst, pale and cold skin, bleeding gums and mouth, rash, fatigue, inability to breathe. Remember that dengue is a debilitating mosquito-borne disease and must be treated promptly. These symptoms are worrisome and require immediate attention.
Are further tests needed if dengue is diagnosed?
When dengue is diagnosed, it is important to monitor symptoms and ensure adequate hydration. Your doctor will recommend complete blood counts to monitor platelet and hematocrit levels. Advanced diagnostics, such as serologic testing, can confirm the different serotypes of dengue. Talk to your doctor and get all the necessary tests done.
Do’s and Don’ts Before the Test
Before the test, it is important to stay hydrated. A well-hydrated patient will be able to provide an accurate blood sample. Avoid any over-the-counter painkillers or anti-inflammatory medications before testing. Keep a detailed record of the symptoms that led you to opt for the test.
What to eat during dengue?
Papaya leaf extract, pomegranate, coconut water, broccoli, herbal tea and yogurt should be included. Eat small and frequent meals and refrain from spicy and greasy foods. Choose citrus fruits, carrots, sweet potatoes, boiled or steamed vegetables. Reduce consumption of alcohol, tobacco, caffeine, fried and fatty foods.
Preventive measures
To prevent dengue, periodically fumigate the surroundings to eliminate mosquito breeding sites, wear long-sleeved clothing or use repellents to avoid mosquito bites. Keep windows closed at night and avoid stagnant water near the house.
