Dengue vs. COVID-19: Understanding the Key Differences

Dengue vs. COVID-19: Understanding the Key Differences


Dengue fever and COVID-19 are two important infectious disease risks that have recently attracted attention on a global scale. Both diseases demonstrate notable variances in terms of transmission, symptoms, treatment, and prevention, despite certain parallels they do share. In order to assist you better understand these diseases and how they affect our world, we shall explore the main distinctions between COVID-19 and dengue in this blog.


Dengue: The virus that causes dengue, specifically Aedes aegypti and Aedes albopictus mosquitoes, largely transmits the disease to people by biting them.

SARS-CoV-2, a new coronavirus that typically spreads through respiratory droplets when an infected person coughs, sneezes, talks, or otherwise moves their mouth or nose, is the cause of COVID-19.


High temperature, excruciating headaches, joint and muscle discomfort, skin rash, and bleeding tendencies including nosebleeds and gingival bleeding are all common symptoms of dengue fever.

The symptoms of COVID-19 include fever, cough, shortness of breath, exhaustion, loss of taste or smell, sore throat, and gastrointestinal problems like diarrhea. Some illnesses may not show any symptoms.

Egg-laying Period

Dengue: Following a mosquito bite, the incubation period for dengue usually lasts 4 to 10 days.

COVID-19: Following virus exposure, the incubation period for COVID-19 typically lasts 2–14 days.


Dengue: Dengue cannot be passed from one person to another; instead, it is transferred through the bite of infected mosquitoes.

COVID-19: COVID-19 is mainly transmitted through respiratory droplets, but it can also be spread by contacting infected surfaces and then touching your face.


Dengue: Although dengue fever typically has a low mortality rate, severe cases might result in dengue hemorrhagic fever or dengue shock syndrome, both of which can be fatal.

COVID-19: COVID-19 is a virus that can range in severity from mild to severe, and certain cases can result in pneumonia, acute respiratory distress syndrome (ARDS), and even death, especially in elderly people and people with underlying medical disorders.

Immunization and Medical Care

Dengue: Since there is no specific antiviral medication to treat this disease, mosquito control techniques are the mainstay of prevention. Although several Dengue vaccines have been created, their accessibility and effectiveness differ.

COVID-19: Several COVID-19 vaccines have been created and approved for use in emergency situations globally, greatly lowering the risk of serious disease and death. There are numerous COVID-19 therapies available, including antiviral drugs and monoclonal antibodies.

Dengue vs. COVID-19: Understanding the Key Differences

Geographical Spread

Dengue: The majority of the world’s tropical and subtropical regions, including sections of Asia, the Americas, Africa, and the Pacific, are affected by dengue.

COVID-19: COVID-19 has had an impact in almost every country and region of the world, albeit to differing degrees.


In conclusion, COVID-19 and dengue are distinct infectious diseases that are brought on by different microorganisms, spread through different routes, and manifest with different signs and symptoms. Effective prevention, diagnosis, and management depend on an understanding of these fundamental distinctions. While vaccinations are now an effective defense against COVID-19, measures to decrease mosquito populations are still the mainstay of dengue prevention. To lessen the impact of these diseases on society, continued research, public health initiatives, and international cooperation are required.
