All You Need to Know About Dengue dengue fever
What is dengue fever?
Dengue fever, also known as breakbone fever, is a vector-borne disease transmitte by the bite of an infected female Aedes mosquito. It can cause by 4 different strains of the same virus (DEN-1 to DEN-4).
Dengue fever can vary from mild, presenting just as fever, to severe. Severe forms include dengue haemorrhagic fever and dengue shock syndrome, all of which are potentially lethal.
An overwhelming 75 – 90% of patients acquire dengue fever without any symptoms, not even fever. This means that many individuals who fall ill during their ‘1st symptomatic dengue fever’ in fact had their 2nd attack. “It has observe and hypothesis. That 2nd attacks of dengue tend to be severe.
Where does the disease occur?
Dengue is prevalent throughout Southeast Asia and the western Pacific islands, but the disease has been spreading rapidly in Latin America and the Caribbean. Nonetheless, regardless of geographical location, dengue outbreaks can occur anytime and anywhere as long as warm weather conditions favour mosquito survival and the mosquitoes are active.
“In line with global warming, we see the widening and spreading of the footprint of the vector Aedes mosquito,” says Dr Leong. “This, in turn, สมัคร ufabet กับเรา รับโบนัสทันที has led to the spread of dengue worldwide. We have seen reports of dengue in Italy and the Mediterranean countries, as well as in Florida, USA, during summer months.”
Where do the mosquitos breed?
In a nutshell, the Aedes mosquito can fly up to 400 metres looking for water-filled containers to lay their eggs but will usually remain close to human habitation. It prefers to breed in clean, stagnant water that’s easily found in our homes. A volume of clean water that approximates a Singapore 20 cent coin is sufficient for breeding.
How does the disease spread?
Dengue fever cannot spread directly from person to person, but a person suffering from dengue fever can infect mosquitoes. A mosquito becomes infected when it takes a blood meal from a dengue-infected person, and dengue spreads when the mosquito later transmits the virus to other people they bite.
“After 5 – 14 days, the virus will mature in the salivary glands of the mosquito and spread to the next victim during the mosquito’s next feed,” explains Dr Leong.
Humans are known to carry the infection across borders or from area to another during the stage. When the virus circulates and reproduces in the bloodstream.
In fact, the general belief was that the Japanese occupation of Southeast Asia during World War 2 provided the means for the growth and spread of the mosquito, and hence the virus in our region. The mosquitoes followed the troops that provided the breeding water and feeds for the mosquitoes.
What are the symptoms of dengue fever?
- Fever, headache
- Muscle and joint aches, high fever, pain behind the eyes
- Vomiting or nausea
Dengue fever presents itself with flu-like symptoms that typically. Show about 1.5 – 10 days. After being bitten by infected mosquito. If it’s a mild case, symptoms will resolve on its own within 2 – 7 days.
The 1st symptoms include fever, headache, muscle and joint aches, high fever, pain behind the eyes, and vomiting or nausea. “Body rash tends to occur a bit later in the illness. “The absence of rash was identifie to risk factor of severe dengue. Largely due to a failure to recognise the illness.”
Severe dengue develops 3 – 7 days after the 1st signs of illness with worsening symptoms, such as severe abdominal pain, persistent vomiting, bleeding gums, vomiting blood, rapid breathing, and fatigue or restlessness.
“One peculiar feature of the infection is that it can cause platelets (tiny cell fragments that form blood clots to stop bleeding) to fall steeply, which leads to bleeding in the internal organs, particularly in the gastrointestinal tract,”
