Can you get dengue again after suffering from it once? It’s a confusing answer.But one which you must know.
That’s what is so dangerous about Dengue.
Dengue virus has four distinct antigenic types. This means if you have Dengue fever from one type, you can still have a fever from the other types.
In fact, Dengue fever from mosquito bites causing concurrent(at the same time two )or sequential(one after another ) infection by the different virus strains is the biggest risk factor to developing Dengue hemorrhagic fever.
Dengue Haemorrhagic fever can occur during a first episode of dengue infection most commonly in infants. Their mothers are most likely having primary immunity to one or more strains of dengue.
Dengue fever is endemic in Asia and Tropical America and so higher rate of Dengue hemorrhagic fever.
Shocking facts about Dengue Haemorrhagic fever :
It will present suddenly.
- Sudden high fever, pharyngitis rhinitis
- A headache: Frontal
- Eye ache: Retro-orbital/behind the eyes.
- Joint pains, muscle pains.Poor appetite.Nausea.Small reddish rash all over chest and arms.
- Bleeding tendencies .nasal bleeding, gum bleeding
20 to 30% of Dengue Haemorrhagic fever may be complicated by shock.
There is a 24 to 36 hours of serious crisis.
40 % to 50% of Dengue hemorrhagic fever patients may die due to shock.But in better circumstances and with the availability of timely hospital admission with high-quality ICU support, mortality has been as low as 1%.
Mechanism of bleeding in Dengue Haemorrhagic fever:
Not totally clear. The following theories are assumed.
- A mild degree of Disseminated Intravascular clotting in Dengue.Liver damage.
- Low platelets. All these acts together to cause bleeding tendencies.
Less than 10% people may have gastrointestinal or intracranial bleeding.
Dengue and Chikungunya are both caused by Aedes aegypti.That’s why in South East Asia both these outbreaks may occur concurrently.
Dengue hemorrhagic fever is also known as Philippine, Thai or Singapore Haemorrhagic fever.
Other similar mosquitoes borne viral fever with rash are West Nile fever, Chikungunya, Onyong-Nyong.
