– Dr. Indira Kedlaya –
With the onset of summer, a serious health threat rears its head in India as is in most parts of South-east Asia every year. The cases of the vector-borne disease Dengue start trickling in as the summer season sets in and typically peak during the monsoon when the environmental conditions are most suited for the breeding of mosquitoes.
Dengue virus is transmitted by female mosquitoes mainly of the species Aedes aegypti and, to a lesser extent, Ae. albopictus. These mosquitoes also transmit other potentially serious vector-borne diseases including Chikungunya, Yellow Fever and Zika virus infection.
With the absence of any credible vaccine against the disease, prevention from mosquitoes remains the most important course. The symptoms of the disease usually begin within seven days of the bite.
Signs and Symptoms:
Dengue fever, also known as breakbone fever, is a severe flu-like illness that affects all age groups. In most people, the fever passes off at its own course. However, in some patients it can cause serious/life-threatening complications like hemorrhagic fever, which can damage the lymph and blood vessels and cause bleeding manifestations. Complications also include severe inflammation of liver and circulatory system failure. It is therefore very important to stay under medical supervision during the course of the disease. If the platelet count dips too low, it may also increase the chances of bleeding, and platelet transfusion may be required depending on the clinical condition of the patient.
Apart from high fever, cold and cough, other symptoms that accompany this viral infection include:
Pain in muscles and joints (back, neck and knee pain especially)
Rashes in body (which usually comes on much later)
Severe headache
Discomfort behind the eyes
Vomiting and diarrhea
Bleeding and confusion (which are extremely severe symptoms)
What one has to do in case of high fever in this season?
Normally, the monsoon season brings with it several kinds of viral infections and fevers. Most of them are largely harmless and subside within a week or so. However, the fever may well indicate Dengue fever in some cases and it is important to be always on the guard against it. So, in case a fever continues for more than two to three days with intense headache, make sure to consult a doctor. Complications such as hemorrhagic fever sometimes set in very early and early medical help is crucial.
Curative measures for Dengue fever:
Like most viral infections, we don’t have any specific treatment or cure for Dengue. It is a self-limiting disease and most Dengue cases are simple Dengue fever. However, timely medical attention and supervision can prevent the risk of complications like persisting vomiting, pain in abdomen, low urine volume, bleeding.
For milder forms of Dengue fever, basic care includes keeping fever under control and consuming a lot of fluids for rehydration. Sometimes, administration of IV fluids is necessary if oral rehydration is not adequate. For controlling fever, just take Paracetamol tablets, cold compresses and avoid using pain killers. At the same time, keep a check on the patient’s platelet count and don’t panic if the platelet counts dips because it is normal for it to drop during the course of the disease. The platelet counts will improve in 7-9 days. Please consult doctors for proper guidance.
Keeping Dengue fever at bay
The only way to control or prevent transmission of Dengue fever is to stop the breeding of mosquitoes as much as possible through a series of measures.
The domestic water storage containers: Cover, empty and clean water tanks, coolers or flower pots on a weekly basis. Don’t let the water stagnate at any place.
Solid waste: Dispose of the kitchen and garden residuals on an everyday basis. Don’t let even solid waste stand at a place for a long time.
Mosquito nets: Use mosquito nets while sleeping to prevent mosquito bites
Adhere to personal protection measures such as wearing long-sleeved clothes. Repellents and vaporizers/mosquito racquets and traps can be used. Doors should be closed as much as possible and keep window shields down to prevent mosquitoes from entering the house
Make sure your children wear full body covering clothes and mosquito repellents when they step out to play in the evening
