Amidst the rising cases of Covid 19 , Dengue seems to be knocking the doors of healthcare systems across tropical countries . Patients suffering from Dengue fever needs to be differentiated from those of Covid 19 cases. Though some cases of Dengue-Covid coinfection were reported from Thailand and Singapore. Know the symptoms of dengue to differentiate from Covid 19 , Spread of dengue and covid 19 , vaccination status of dengue and how to prevent the spread of these diseases.
DENGUE VS COVID 19
It is a viral disease spread through bite of mosquitoes mainly by speices Aedes aegypti and to a lesser extent by Aedes Albopictus
Covid 19 (SARS Cov2) is an infectious viral disease spread from human to human
SPREAD OF DENGUE VS COVID19 :
Aedes aegypti female mosquito lives in urban habitats and breeds mostly in man made containers
It feeds during day times and peak biting periods are early in the morning and in the evening before sunset
The Eggs of mosquito once laid can survive for months and will hatch when they are in contact with water
The COVID-19 virus spreads primarily through droplets of saliva or discharge from the nose when an infected person coughs or sneezes
So it’s important that you also practice respiratory etiquette (for example, by coughing into a flexed elbow).
SIGNS AND SYPMTOMS OF DENGUE VS COVID
WHO classified Dengue into 2 categories : Dengue (with/without warning signs) and severe dengue
Common symptoms are like that of the flu, with patients experiencing:
pain behind the eyes
muscle and joint pain
As the disease progresses, patients can also suffer from respiratory distress, bleeding from the nose and gums and have a rapid drop in blood pressure leading to shock. If left unmanaged, this can lead to death.
COVID-19 affects different people in different ways. Most infected people will develop mild to moderate illness and recover without hospitalization.
Most common symptoms:
Less common symptoms:
Aches and pains.
loss of taste or smell.
a rash on skin, or discolouration of fingers or toes.
difficulty breathing or shortness of breath.
chest pain or pressure.
loss of speech or movement.
TREATMENT OF DENGUE VS COVID 19
There is no specific treatment for dengue fever.
For Dengue without warning symptoms : Fever reducers can be taken to control the symptoms of muscle aches and pains, and fever.The best options to treat these symptoms are acetaminophen or paracetamol.
For severe dengue : medical care by physicians and nurses experienced with the effects and progression of the disease can save lives – decreasing death rates from more than 20% to less than 1%
For treatment of COVID-19 , there are many ongoing clinical trials evaluating potential treatments across the globe.

PREVENTION OF DENGUE AND COVID :
Prevention of mosquito breeding:
Disposing of solid waste properly and removing artificial man-made habitats that can hold water;
Covering, emptying and cleaning of domestic water storage containers on a weekly basis;
Applying appropriate insecticides to water storage outdoor containers;
Personal protection from mosquito bites:
Using of personal household protection measures, such as window screens, repellents, insecticide treated materials, coils and vaporizers. These measures must be observed during the day both inside and outside of the home (e.g.: at work/school) because the primary mosquito vectors bites throughout the day;
Wearing clothing that minimises skin exposure to mosquitoes is advised;
Educating the community on the risks of mosquito-borne diseases;
Emergency vector control measures such as applying insecticides as space spraying during outbreaks may be used by health authorities

VACCINATION STATUS OF DENGUE AND COVID 19
The first dengue vaccine, Dengvaxia® (CYD-TDV) developed by Sanofi Pasteur was licensed in December 2015 and has now been approved by regulatory authorities in ~20 countries.
Use of the vaccine is targetted for persons living in endemic areas, ranging from 9-45 years of age, who have had at least 1 documented dengue virus infection previously.
