Chikungunya fever
INTRODUCTION
Chikungunya fever is a mosquito-borne viral disease characterized by an abrupt onset of fever
chikungunya fever does not often result in death. The condition can cause severe problems
mostly in adults with other chronic illnesses a person who has been infected once is likely to be
protected from future infections.
SPREAD WORLD WIDE :
Chikungunya fever is widespread across the world and was first reported in Africa asia and
islands in the indian and pacific oceans in 2013 the first case of the disease was reported in the
Americas on islands in the caribbean since then more than 1.7 million suspected cases of the
disease has been reported in the Caribbean islands in latin american countries and in the united
states it is believed that the condition was imported into these areas by infected travelers causes.
MOSQUITOS INVOLVED:
Chikungunya fever is caused by the chikungunya virus the virus is transmitted by bites from
female infected mosquitoes the two species of mosquitoes involved are aedes albopictus and
aedes aegypti which predominantly bite during the day although there may be peaks of activity
in the early morning and late afternoon.
TRANSMISSION :
These mosquitoes also transmit dengue fever yellow fever and zika virus both species are
mostly found biting outdoors but aides aegypti will also readily feed indoors outbreaks of
infection are common and often occur after the rainy seasons when mosquitoes breed more
actively after being bitten by an infected mosquito the onset of illness occurs usually between
three to seven days but can range from one to twelve days the virus is transmitted rarely from
mother to newborn around the time of birth.
In theory the virus could be spread through a blood transfusion although there are no known
reports of this happening risk factors hosts with heart disease respiratory disease hypertension
and alcohol disease tend to have an increased risk of developing severe complications such as
heart failure pancreatitis myocarditis periocarditis renal failure hepatitis pneumonia.
SYMPTOMS:

If you are older than 45 years of age symptoms sudden onset with high fever the fever is
usually above 102 degree Fahrenheit and sometimes reaches 104 degrees Fahrenheit.
joint pain is reported in 87 to 98 percent of cases and occurs in more than one joint rash.
and other symptoms may include a headache muscle pain fatigue joint swelling nausea
vomiting or diarrhea .
The symptoms usually resolve over a few days however some people are left with ongoing joint
pains which may continue for weeks months and even years diagnosis and treatment to make a
diagnosis.
PREVENTION AND TREATMENT:
The doctor will rule out other conditions that share the same symptoms as the fever the
doctor may also need to rule out whether you have traveled to or spent time in an area in
which the virus is present within the last 12 days.
The doctor may use a sterological test such as enzyme-linked immunoabsorbent assays or
elisa to confirm the presence of igm and igg anti-chikungunya antibodies igm levels are
at peak three to five weeks after the onset of illness and may persist for about two months
viral isolation may also be used treatment there is no specific treatment.
For the condition most people get better on their own and recover completely if treatment
is required the aim is to relieve symptoms usually with rest fluids and medications such
as acetaminophen and ibuprofen.
If you are going to a place with an outbreak the following can be done to lower your
chances of being bitten wearing bite proof long sleeves and long pants staying indoors
where there is air conditioning or screened in areas wearing a mosquito repellent that has
deet if you are going outside without sleeps dumping out or eliminating any standing
water in your house where mosquitoes may lay eggs and develop as a larva.
