FAQ's on Dengue

Q 1    What is dengue fever?
Ans    Dengue (pronounced den' gee) is a disease caused by any one of four closely related dengue viruses (DENV 1, DENV 2, DENV 3, or DENV 4). Dengue fever is a disease caused by mosquito-borne viral infection transmitted by the Aedes mosquitoes, which normally attacks in day time. It is not spread by one person to another directly.

Q2    What is dengue haemorrhagic fever?
Ans    DHF is a more serious form of dengue infection. It can be disastrous if cannot diagnose and not accurately deal with this in a timely manner. DHF is caused by infection with the same viruses that cause dengue fever.

Q3    How is dengue fever diagnosed?
Ans    Dengue fever is diagnosed clinically in patients that present with the signs and symptoms and have a compatible and recent travel history. Dengue fever may however be confirmed only with specialized testing offered at the National Institute of Communicable Diseases. Laboratory investigation includes RT-PCR and virus isolation in acute patients (patients that have been ill for less than one week) and serology. Serology is most informative when repeat specimens (i.e. acute and convalescent) are submitted for investigation.

Q4    How soon after exposure do symptoms appear?
Ans    The time between the bite of a mosquito carrying dengue virus and the start of symptoms averages from 4 to 6 days, with a range of 3–14 days. An infected person cannot spread the infection to other persons by direct contact, but can be a source of dengue virus for mosquitoes for about 6 days.

Q5    What are the symptoms of the disease?

Ans    As a treatment, still no specific treatment invent but mostly fluid replacement therapy use if it’s diagnosed at prior stage. Patient should take rest & use plenty of fluids.

Q7    What can be done to reduce the risk of acquiring dengue?
Ans    Still no vaccine invented which can take as a precaution. For reduce the risk of dengue we need take care on some issues like our environment or resident area should be clean, present of hold water should be null, outer area should be cleaned & covered, Water storage container should be clean once in a week, proper exit of rain water, last but not least reduces the risk of mosquitoes coming indoors.

Q8    How can we prevent epidemics of dengue hemorrhagic fever (DHF)?
Ans    The emphasis for dengue prevention is on sustainable, community-based, integrated mosquito control, with limited reliance on insecticides (chemical larvicides, and adulticides). Preventing epidemic disease requires a coordinated community effort to increase awareness about dengue fever/DHF, how to recognize it, and how to control the mosquito that transmits it. Residents are responsible for keeping their yards and patios free of standing water where mosquitoes can be produced.

Q9    Where can outbreaks of dengue occur?
Ans    Mainly where Aedes aegypti (sometimes also Aedes albopictus) mosquitoes are found in large numbers those areas occur highly outbreaks of. Apart from this, tropical urban areas as well as rural areas also can effect but depends on the locality because mostly introduced in migratory workers area.
