INTRODUCTION
Chikungunya is a mosquito-borne viral disease
first described during an outbreak in southern
Tanzania in 1952. It is an RNA virus that belongs
to the alpha virus genus of the family Togaviridae.
The name “chikungunya” derives from a word in
the Kimakonde language, meaning “to become
contorted”, and “that which bends up” describes
the stooped appearance of sufferers with joint pain
(arthralgia).The fever is locally also named as
“Langrajor”
DEFINITION
“ It is spread by bite of “Aedes aegypti” mosquito
which usually bite during day light hours. The
name is derived from Swahili word meaning “that
which bends up” .Describes that posture patient
assume to relieve the severe joint pains.

epidemiology
“Chikungunya is caused by the chikungunya virus
(CHIKV), an arthropod-borne virus (arbovirus).
Chikungunya fever is one of the most
important mosquito-borne viral diseases”.
HISTORY OF EPIDEMIOLOGY
Epidemiological criteria: residing or having visited
epidemic areas, having reported transmission
within 15 days prior to the onset of symptoms. In
late 2013, the first local (autochthonous)
transmission in the Americas was documented. In
India it was first reported in 1963 at Calcutta. Its
recent epidemic which started in December 2005,
involving southern and central India has grabbed

6. much attention. Chikungunya is not considered to
be fatal. However, in 2005 - 2006, 200 deaths have
been associated with chikungunya of Reunion
Island and widespread outbreak in southern India.
A recent report of large scale outbreaks of
chikungunya virus in southern India has confirmed
the re-emergence of this virus. The precise reasons
for the re-emergence in the Indian sub-continent as
well as in southern India, of this viral infection, are
due to a variety of social, environmental,
behavioral and biological changes.

ETIOOLOGY OF CHICKEN GUNYA FEVER
Causative organism – Chikungunya virus
Alternate name – Buggy Creek virus
ICTV acronym – CHIKV
Humans and other primates are the natural hosts
for the chikungunya virus. The virus is spread to
humans by the bite of an infected female, Aedes
species mosquito – Aedes aegypti or Aedes
albopictus.
RISK FACTORS OF CHIKUNGUNYA FEVER
People of all ages can become infected with
CHIKV and suffer a debilitating illness, but only
20% of the people that are infected will suffer any
illness symptoms. Infants, senior citizens, and
people already suffering from other underlying
illnesses are at greater risk of a severe illness. To
date no locally-acquired cases have been reported
among Virginia residents. T here is a risk of

VIRUS CLASSIFICATION
Group: Group IV [(+) SS RNA]
Family: Togaviridae
Genus: Alphavirus
Species: Chikungunya virus
MODE OF TRANSMISSION
Chikungunya is spread by the bite of an
infected Aedes mosquito, primarily Aedes
aegypti.
Recently, research by the Pasteur Institute
in Paris has found a mutation that enables
it to be transmitted by Aedes albopitcus
(Tiger mosquito), which appears to be the
cause of the recent epidemic in Asia.
Few cases of mother to foetus infection
have been reported from Asia, which

RESERVOIR
Humans are the major source of reservoir

Some non human primates like monkeys
are the reservoir in Africa, in which it is
transmitted by Aedes fureifer and Africans.

10. adults in whom the clinical picture may be
dramatic.
The abrupt onset of clinical manifestations
follows an incubation period of 2 to 3 days.
Silent CHIKV infections do occur, but the
number and incidence is not yet known.
Fever is sudden onset, high grade (> 40° C,
104° F) with chills and rigors; fever is
biphasic or saddle back (fever subsides in 2
to 3 days and than comes back after 1 day);
the second phase of fever is usually
associated with bradycardia.
Fever is associated with constitutional
symptoms such as headache, photophobia,
conjunctivitis, anorexia, nausea, and
abdominal pain.
Arthralgia/arthritis in chikungunya has
been quite crippling in recent outbreaks in
southern India. Migratory polyarthritis
mainly affects the small joints of hands,
wrists, ankles, and feet. Rash may appear
at the outset or several days after the illness
11. i.e., in the convalescence phase.
Dermatological manifestations observed in a
recent outbreak of chikungunya fever in southern
India include the following4:
1. Maculopapular rash.
2. Blotchy, nasal erythema.
3. Freckle-like pigmentation over centro-facial
area.
4. Flagellate pigmentation on face and extremities.
5. Lichenoid eruption and hyperpigmentation in
photo distributed areas.
6. Multiple aphthous–like ulcers over the scrotum,
crural areas, and axilla.
7. Lymphoedema in acral distribution (bilateral/
unilateral).
8. Multiple ecchymotic spots (children).
9. Vesiculobullous lesions (infants).
10. Subungual haemorrhage.
11. Photourticaria.
12. Acralurticaria.
12. Fever typically last for two days and then abruptly
comes down. However, joint pain, headache,
insomnia, and various degrees of prostration last
for a variable period, usually for about 5 to 7 days.
Chikungunya is a self-limiting disease, and
recovery is the rule, but little mortality has been
reported in the recent outbreaks in southern India.
In July 2006, a team analysed the virus RNA and
determined the genetic changes that have occurred
in various strains of the virus and identified the
genetic sequence which led to the increased
virulence of the recent strains
The symptoms are most often clinically
indistinguishable from those observed in
dengue fever.
Indeed, simultaneous isolation of both

dengue and chikungunya from the sera of
some patients has been reported earlier,
indicating the presence of dual infections
Therefore, it is very important to clinically
distinguish dengue from chikungunya virus
infection.
Unlike dengue, haemorrhagic
manifestations are relatively rare, and as a
rule, shock is not observed in chikungunya
virus infection.
Other important clinical conditions for
differential diagnosis are West Nile fever,
O’nyong-nyong fever.
DAIGNOSTIC INVESTIGATIONS OF

14. Institute of Virology at Pune, Maharashtra.
Chikungunya virus infection should be
considered in patients with acute onset of
fever and polyarthralgia, especially
travelers who recently returned from areas
with known virus transmission.
Laboratory diagnosis is generally
accomplished by testing serum or plasma
to detect virus, viral nucleic acid, or virus-
specific immunoglobulin (Ig) M and
neutralizing antibodies.
Viral culture may detect virus in the first 3
days of illness; however, chikungunya
virus should be handled under biosafety
level (BSL) 3 conditions.
During the first 8 days of illness,
chikungunya viral RNA can often be
identified in serum.
Chikungunya virus antibodies normally
develop toward the end of the first week of
illness. Therefore, to definitively rule out
the diagnosis, convalescent-phase samples
15. 10. 2min To understand

should be obtained from patients whose

Common laboratory tests for
chikungunya include for instance RT-PCR
and serological tests
TREATMENT OF CHIKUNGUNYA FEVER
There is no specific treatment for
chikungunya. The illness is usually self-
limiting and will resolve with time.
Supportive care with rest is indicated

Ibuprofen, paracetamol relieve symptoms
of fever and aching.
Movement and mild exercise tend to
improve stiffness and morning arthralgia,
but heavy exercise may exacerbate
rheumatic symptoms.
In unresolved arthritis refractory to
NSAIDs, chloroquine phosphate (250
mg/day for several weeks) has given good
results.
Vaccine for commercial purpose is not
available and is under trial.

complications
COMPLICATIONS OF CHIKUNGUNYA
FEVER
Chikungunya is a self-limiting illness. The major
causes for morbidity are severe dehydration,
electrolyte imbalance, and hypoglycaemia.
Recovery is the rule, but 10 - 15% patients had
chronic joint pain and stiffness.
Major complications, though rare, are:–
1. Bleeding disorder (epistaxis, UGI bleed) as it
causes thrombocytopenia, superadded by
injudicious use of NSAIDs.
2. Neurological complications: a.
Meningoencephalitis. b. Paresis of limbs.
c. Slurring of speech.
3. Cardiovascular decompensation.

5. Deaths – Few deaths have been reported in the
recent epidemic in Reunion Island and in southern
India.
PREVENTION OF CHIKUNGUNYA FEVER
As there is no vaccine available yet, the only way
to prevent it is to eliminate mosquito breeding
sites and to prevent mosquito bites.
Aedes mosquito vector for this disease
breeds in artificial accumulations of water
in and around human dwellings, such as
water found in disused wares, broken
bowls, flower pots, earthen pots. Therefore,
these sites should be eliminated by
responsible human behaviour and social
education.

fever?
19. Aerosol spray of ultra low volume
quantities of malathion or sumithion (230
ml/litre) has been found to be effective.
Mosquito net and repellents which contain
20 - 50% DEET (N, N-diethyl-meta-
tolnamido) should be used to prevent
mosquito bites.
20. As mosquito bites during daytime,
mosquito repellants should be used during
daytime also and, not only during the night.
Use of full sleeve clothing is effective in
preventing mosquito bites.

CHIKUNGUNYA FEVER ABOUT MOTHER
Chikungunya fever with pregnancy There
have been cases of mother-to-infant
infection which have occurred between 3
and 4 months into pregnancy.
Before and after that period in pregnancy,
cases have not been recorded.
IgG that is produced around day 15, passes
through the placenta and confers immunity
to the foetus.
However, there is a 48 per cent risk of
infection at birth if the virus is present in
the mother’s blood.
Such an infection in the foetus is rarely
serious, and more than 90 per cent of the
infected newborns recover quickly without
sequelae.
