COVID-19 Versus Dengue: What Do We Need to Know?
COVID-19 is spreading rapidly worldwide. It was recognized as a pandemic by the World Health Organization (WHO) on March 12th. In Singapore, there are 1309 confirmed cases as of April 5th, 2020.
With the outbreak of coronavirus worldwide, another public health concern faces neglect by the public: the Dengue virus (DENV). This life-threatening mosquito-borne disease is highly active in Singapore for years. People may not realize that the rise of dengue fever cases is looming in Singapore. There are 4776 dengue cases recorded as of March 28th, 2020. Twice the number compared to the same period of 2019.
Death cases: COVID-19 versus Dengue
How deadly is COVID-19, and how can Dengue be lethal to us? In Singapore, the total of deaths from COVID-19 rose to 6 death cases on April 4th. However, the Dengue virus took a total of 20 lives in 2019. So far, there are no cases of deaths due to the Dengue virus in 2020.
You may wonder if we can differentiate between the symptoms of COVID-19 and Dengue fever without laboratory testing. Here are some ways to tell the difference:
- People who are infected with Dengue virus share similar symptoms as those with COVID-19, such as high fever and headache.
- However, they may also develop other symptoms such as joint and muscle pain, nausea, vomiting, rashes of the skin, and mild bleeding from nose and gum.
- Respiratory symptoms such as cough, sore throat, and breathing difficulties are not common in the Dengue virus.
- The spread of COVID-19 is mainly person-to-person.
- COVID-19 can be passed over to a healthy person by nasal discharge and saliva droplets from coughs and sneezes of a person infected with COVID-19.
- The virus can easily infect a healthy person if the person uses his or her contaminated hand to rub or touch the eyes, nose, or mouth.
- Not surprisingly, the infection of COVID-19 can happen through the inhalation of infected droplets into the lungs.
- In the case of the Dengue virus, the transmission of the disease is vastly different compared to COVID-19. It is a vector-borne disease that requires the help of Aedes mosquitoes to spread the virus.
The Prevention of Dengue
Dengue virus cannot be transmitted directly from one human to another.
Instead, it transmits through an insect vector – mosquitoes. By pulling mosquitoes out of the transmission or infection chain, we can stop the transmission of the virus. In other words, avoiding mosquito bites is an essential aspect in the prevention of Dengue.
Eliminate Mosquito Breeding in and Around Your House
Controlling the mosquito population is essential in the fight against Dengue. Aedes mosquitoes breed in clean water found in natural and human-made containers. They can breed in water bodies that are as small as the size of a 20 cents coin, so all stagnant water must be eliminated to prevent mosquito breeding. Practice the following 5-step Mozzie Wipeout recommended by the National Environment Agency:
- Turn any unused pails
- Change water in vase regularly
- Flip flower pot plates
- Loosen hardened soil in flowerpots or planter boxes
- Clear roof gutter and place biological control (Bti)
Prevent Mosquito Bites
We can minimize our risk of getting mosquito bites by taking extra precautions when visiting places that are prone to mosquito attacks.
Long sleeve tops and long pants offer basic protection against mosquito bites. There are a variety of mosquito repellents that are made of either chemical compounds or natural plant extracts. You may choose any mosquito repellent of your preference, or that is available to you. However, it is essential to follow the instructions and reapply the repellent regularly as they may be rubbed or washed off during activities.
COVID-19
WHO and CDC recommend some steps to protect you and the others from the virus. At the top of the list, we need to maintain good hygiene practices. Wash your hands frequently with soap and water for at least 20 seconds to properly remove germs from your hands. Hand sanitizers with at least 60% alcohol content can be used if soap and water are not available. It is also important to avoid touching your face or eyes with unwashed hands.
Pro Tip: The best way to prevent COVID-19 is to avoid exposure to the virus and get vaccinated.
Social Distancing
Social distancing plays an integral part in the prevention of COVID-19 as you may pick up someone else’s respiratory droplets if you are standing too close to each other. A distance of at least 1 meter between individuals is recommended to prevent the transmission of the coronavirus. Social distancing is even more important in communities where COVID-19 is spreading. Avoid close contact with people who are sick to protect both the person and yourself.
Be socially responsible. Seek medical attention if you are sick or experiencing respiratory symptoms. Follow the doctor’s advice and stay at home to prevent the disease from spreading. Cover your mouth and nose with a tissue when coughing or sneezing to prevent the spread of respiratory droplets. Lastly, wear a facemask to prevent the spread of respiratory droplets to other people.
Cleaning and disinfection should be carried out on frequently contacted surfaces.
The NEA provided a list of household products that can be used for disinfection. Several sources reported that the virus was able to last on various surfaces for up to days. Thus, disinfection should be done regularly.

The year 2020 started with the uncertainties caused by the 2019 novel coronavirus disease (COVID-19). Coronaviruses are a large family of viruses, which include those that cause the Middle East Respiratory Syndrome (MERS-CoV) and Severe Acute Respiratory Syndrome (SARS-CoV).
SARS-CoV is a well-known coronavirus in Singapore as its outbreak in 2003 killed 33 people while leaving various social and economic impacts.
Although COVID-19 is more contagious compared to SARS and MERS, it is less fatal than the two, meaning that it is less likely to kill.
How active is the Coronavirus in Singapore?
There are 85 confirmed cases of Coronavirus in Singapore as of 21 Feb 2020. Moreover, there are currently 5 clusters in Singapore, with the Grace Assembly of God Church being the largest cluster. Most of the cases are linked to one another, but the emergence of cases without any known links to other cases caused Singapore to raise the DORSCON level to orange.
What are the Symptoms of Coronavirus (COVID-19)?
The initial stage or main symptoms of COVID-19 are fever, cough, and shortness of breath.
It is hard to differentiate between COVID-19 and common cold without other indicators such as the recent travel record to mainland China or close contact with other confirmed cases.
In most cases, the symptoms will appear within 5 to 6 days. However, the duration of the period between infection and the onset of symptoms can be as long as 14 days.
How can the symptoms of the Coronavirus be confused with dengue? Are the symptoms of dengue and the Coronavirus similar?
The patient infected with the dengue virus shares similar symptoms as those with COVID-19, such as high fever and headache. However, the one who has the dengue virus may develop other symptoms such as joint and muscle pain, nausea, vomiting, rashes of the skin, and mild bleeding from the nose and gum. Respiratory symptoms such as cough, sore throat, and breathing difficulties are not common in the case of the dengue virus.
In Singapore, a 57-year-old lady who was first admitted as a dengue patient turned out to test positive for COVID-19 on 18 Feb 2020.
After several laboratory testing, MOH (Ministry of Health) had confirmed that this lady is the only known person in Singapore who is infected with both dengue and COVID-19.
Now, there is a deep concern about the laboratory tests of COVID-19, which show negative results initially but ended up diagnosed as COVID-19 in the final examination. It may take more than one test to confirm a COVID-19 case as the viral material collected in the initial test sample may be too little for the test to detect the virus.
COVID-19 Versus Dengue: What Do We Need to Know?
What Animals Carry Coronaviruses?
There are many coronaviruses known to circulate among animals and birds in the world. Nonetheless, only seven of them are capable of causing disease in humans. Some animals that are closely related to coronaviruses include bats, camels, and cats. The animal source of the COVID-19 virus has not yet been identified.
An animal from the live animal market in China may have caused the first reported human infections. Let’s look at the case of SARS coronavirus. The common perception is that it originated from bats that transmitted it to humans directly. Instead, it jumped to infect humans via civet cats. Furthermore, MERS coronavirus was also believed to have originated from bats but jumped to infect humans via camels.
Can Pests Carry the Coronavirus?
In view of WHO (World Health Organization), there is no evidence at present to show COVID-19 can infect pests or spread through pests. Currently, it spreads only by infected people.
Can Pest Control Prevent the Coronavirus?
While pests may not spread COVID-19, controlling the population of pests around you reduces the number of disease-carrying pests such as mosquitoes and rodents.
Some of the pest control companies provide disinfection service that can effectively kill various germs, including coronaviruses.
Pest management professionals are equipped with the necessary chemicals and equipment to eliminate harmful pathogens.
Pro Tip: Pest infestation in your home is bad anyway, but the ongoing COVID-19 pandemic can make them even more dangerous than usual.
