What is Dengue Fever?
Dengue is a rapidly spreading mosquito-borne viral disease . The dengue virus is transmitted mainly by female Aedes mosquitoes. Once the mosquito is infected, it is infected for the rest of its life. The four types of viruses that cause dengue are different but closely related. Curing an infection in one person provides lifelong immunity against the type. However, other types of infections later increase the risk of severe dengue. Symptoms appear 4-10 days after the bite of an infected mosquito. It is not transmitted by direct transmission from one person to another.

Update on Dengue (Epidemiology Unit, Ministry of Health)
65 51659 suspected dengue patients in the year 2018 and 18835 by 2020 have been reported to the Epidemiology Unit island wide.
Approximately 27.9% of dengue patients were reported from the Western Province. The highest number of dengue patients was reported during the 29th week of 2017.

WHAT ARE THE SYMPTOMS AND SIGNS OF DENGUE FEVER?
Dengue should be suspected when there is a high fever (40 ° C / 104 ° F) with the following 2 symptoms during the fever phase:
Pain behind the eyes
Muscle and joint pain
COMPLICATIONS OF DENGUE FEVER?
About 3-7 days after the onset of the disease, the patient is referred to the critical phase. When the patient has a fever (less than 38 C / 100 below F), a severe dengue-related warning may be issued. Severe dengue is a life-threatening complication caused by plasma leakage, fluid accumulation, respiratory distress, severe bleeding, or organ failure.
Warnings that physicians should look out for include,
Severe abdominal pain
Blood in the vomit
DENGUE HEMORRHAGIC FEVER
Having antibodies to the dengue virus from a previous infection
Under 12 years of age
Being a woman
May cause a weakened immune system
Dengue hemorrhagic fever is the most serious disease known as dengue hemorrhagic fever in a small percentage of people with dengue fever.
DENGUE SHOCK SYNDROME (DSS)
DSS is a severe form of dengue. It can be deadly.
In addition to mild dengue fever symptoms, the person may experience,
• Severe abdominal pain
• Sudden high blood pressure or rapid drop in blood pressure
Leakage of blood vessels
If patients show these symptoms at a critical stage, close monitoring over the next 24-48 hours is essential to ensure proper medical treatment and the risk of complications and death.
Dengue is a virus, so there is no definite cure or cure. However, intervention may be helpful based on how severe the disease is.
If the symptoms worsen, hospitalization will allow the person to be properly monitored.
• Prevention of dehydration: High fever and vomiting can dehydrate the body. The person should drink pure water rather than tap water. Re-dehydrating salts also help to replace fluids and minerals.
Painkillers such as paracetamol: These help to reduce fever and relieve pain.
Dengue may require more severe forms: Intravenous (IV) fluid supplement
Blood transfusion for patients with severe dehydration
PREVENTION AND CONTROL?
If you know you have dengue, avoid further mosquito bites during the first week of illness. During this time the virus can circulate in the bloodstream, so you can transmit the virus to new mosquitoes that are not infected.
Proximity of mosquito vector breeding grounds to human habitation is a significant risk factor for dengue as well as other diseases transmitted by Aedes mosquitoes. Currently, the main way to control or prevent the transmission of the dengue virus is to fight mosquito vectors. This is achieved by:
— Prevention of mosquito breeding:
Prevent mosquito breeding habitats by changing environmental management and modification.
Proper disposal of waste and removal of man-made habitats that can retain water.
• Weekly covering, emptying and cleaning of indoor water storage containers.
Apply suitable pesticides to water storage outdoor containers.
— Personal protection from mosquito bites:
Use personal home protection measures such as window screens, repellents, insecticide treated materials, coils and evaporators. These actions should be monitored inside and outside the home during the day (eg at work / school) as primary mosquito carriers bite throughout the day.
It is advisable to wear clothing that minimizes skin exposure to mosquitoes.
— Community Participation:
Raising awareness on mosquito-borne diseases in the community.
Engage with the community to improve participation and mobilization for sustainable vector control.
– Conclusion –
Although dengue may seem like an epidemic, there are many ways to prevent it from spreading to our homes. Maintain hygiene, regularly check stagnant water, and take mosquito-bite prevention measures to make sure your home is mosquito-free
