Top 5 dengue myths debunked

By Dr. Verna Lee Kar Mun / International Medical University

In Malaysia, dengue is becoming prevalent. During the epidemiological week 5 of 2023, the nation reported 2,159 dengue cases, according to data from the World Health Organization (WHO).

According to a press release from the International Medical University Malaysia (IMU), the total number of dengue infections for 2022 increased by more than 150% compared to the previous year, and the number of deaths from dengue rose by 180%. It added that many people appeared to have become complacent about the threat that dengue poses.

Despite this, some people are misled by false information about the illness, which could do more harm than good because it gives people a false sense of security and makes them vulnerable to the true risks of dengue.

To debunk these five myths, associate professor Dr. Verna Lee Kar Mun, a family medicine specialist at the IMU, addresses them.

Myth No. 1: You can only get dengue once in your lifetime

Fact: There are four dengue serotypes and this means a person can get infected up to four times, once with each serotype. Total immunity is only possible if a person has been infected with each of the four serotypes.

However, before you start thinking it’s a good idea to get infected four times, bear in mind that subsequent infections are likely to be more serious than the first, and each infection only increases your chances of getting severe dengue. As severe dengue is a serious illness that requires hospitalisation and may lead to devastating consequences such as organ failure, repeated dengue infections are definitely the wrong way to go as far as immunity is concerned.

Myth No.2: As long as I don’t feel sick, there is no danger

Fact: There are three different stages of dengue fever. It begins with the Febrile Phase, characterised by 1-2 days of high fever that begins suddenly. During this time, patients are likely to have body aches, headache with pain behind the eyes, flushed faces and sometimes blotchy skin or rashes.

Next is the Critical Phase. Ironically, this is when the fever subsides, and many people may feel that they are getting better. However, these one to two days are when a patient can possibly go into shock if the capillaries are leaking plasma, leading to a sudden drop in blood pressure. It is this phase which will determine if patients get better and proceed to the Recovery Phase (when the patients are able to reabsorb fluids and the pulse stabilises) or get worse and suffer severe dengue.

“Many viral illnesses such as dengue are self-limiting, which means they will naturally subside. In most cases, patients only need self-care at home, and the most important thing to remember is to take plenty of fluids to prevent the dehydration that comes with plasma leakage. Anyone who gets dengue fever should aim to drink at least three litres of water daily for the first three days,” says Dr Verna.

Myth No. 3: Dengue is just a common mild illness

Fact: While most people who get infected with dengue are able to recover at home, this does not mean that dengue is nothing to worry about.

“An estimated 1% of patients will experience severe dengue, also known as haemorrhagic dengue, which will require hospitalisation. Bleeding can begin in the Febrile Phase, usually in the skin or gums and if it is not managed well, the patient’s condition can worsen during the critical phase, which is when most people are admitted,” says Dr Verna. “Those with a healthy immune system usually recover in two days, but if there is inflammation affecting the organs such as the heart, liver or brain, it can take up to a week or longer if there are complications.”

For people who already have low blood pressure, the symptoms may begin earlier, and women who are menstruating may experience heavier bleeding, she adds.

Other signs of severe dengue include severe pain in the abdomen, persistent vomiting, rapid breathing, and blood in the vomit or stool.

Myth No. 4: I can only test for dengue after three days

Fact: “It is true that the initial symptoms are vague, as a fever can be a sign of many different illnesses. But with dengue, the high fever usually comes suddenly, whereas with COVID-19, for example, the onset of fever is slower. The S1 dengue rapid antigen test can detect dengue from the first day, so don’t delay seeking medical advice if you suddenly develop a high fever,” explains Dr Verna.

Remember, the febrile phase only lasts one to two days, thereafter the critical phase is when patients can suddenly take a turn for the worse.

Myth No. 5: I don’t need to do anything about dengue prevention; there is already fogging going on in my area

Fact: Efforts such as fogging helps to kill adult mosquitoes and getting rid of stagnant water in public drains and other places helps to prevent breeding sites; however, these involve a lot of cost and manpower, and are only partially effective. In 2009/2010, the estimated cost was RM777 million and it is undoubtedly higher today, and there is even evidence that mosquitoes have grown resistant to the common insecticides used in fogging.

“Authorities are already testing new methods, such as the use of genetically modified mosquitoes in hotspots and now, there is news of a vaccine being reviewed – it will be good to have more ways to protect against dengue,” says Dr Verna.

However, this is not a good excuse to let down our guard, she says. “On a personal level, all of us can do something at home to help prevent mosquito bites and breeding sites. Remember, you can quarantine a person, but you can’t quarantine a mosquito; they are everywhere. We need to make a bigger effort to protect ourselves and our loved ones by making sure our home environment is clear of any breeding sites, covering up exposed skin and using mosquito repellents, especially during sunrise and sundown.”

Lastly, Dr Verna also cautions against wishful thinking and the idea that dengue can be cured.

“There is presently no cure for dengue, nor any specific treatment that can help, not even antivirals. There is no harm in drinking fruit juices and other fluids as these can help prevent dehydration, however they are not cures,” she says. “As dengue is a self-limiting illness and most people recover without the need for hospitalisation, we just need to remember that our body can do the work, and we just need to help it do so.”
