Martinique confirms 3 cases of chikungunya virus

dec 26, 2013

In Martinique island 3 cases of locally acquired chikungunya are confirmed in the laboratory (PCR). Testresults are pending for another 27 cases.

Situation épidémiologique actuelle en Martinique

En Martinique, trois infections par le virus chikungunya ont été
confirmées par RT-PCR, l’une par le CNR des arbovirus (Institut de
Recherche Biomédicale des Armées) à Marseille et les deux autres par
le CNR associé des arbovirus à l’Institut Pasteur de Guyane. Ces personnes
n’ont pas voyagé dans une zone à risques les deux semaines
précédant l’apparition des signes cliniques.

Ces confirmations révèlent qu’une chaîne de transmission du virus s’est
établie en Martinique ce qui correspond à la phase 2 du Psage en Martinique
(transmission autochtone modérée) qui a été déclarée le 19 décembre 2013.
Le dispositif de surveillance épidémiologique a permis de détecter 27 cas
suspects cliniquement évocateurs pour lesquels les résultats des examens biologiques sont attendus.

Les mesures de surveillance renforcée et de lutte antivectorielle
doivent se poursuivre et s’intensifier pour prévenir la survenue de
cas secondaires et l’apparition de foyers et ainsi éviter la diffusion
du virus.

Epdemiological update Martinique

In Martinique 13 cases of chikungunya virus have been confirmed via RT-PCR.

5 cases are classified as probable cases.

43 cases are clinical suspect, testresults are pending.

Situation ?pid?miologique actuelle en Martinique

En Martinique, treize infections par le virus chikungunya ont ?t?
confirm?es par RT-PCR, et cinq cas ont ?t? class?s comme probables.
La moiti? de ces cas r?sident dans un m?me quartier de Fort de
France. Les personnes concern?es n?ont pas voyag? dans une zone ?
risques les deux semaines pr?c?dant l?apparition des signes cliniques.

Ces donn?es confirment l?existence d?une cha?ne de transmission du
virus en Martinique qui est plac?e en phase 2 du Psage en Martinique
(transmission autochtone mod?r?e) depuis le 19 d?cembre 2013.
Le dispositif de surveillance ?pid?miologique a permis de d?tecter 43 cas
suspects cliniquement ?vocateurs pour lesquels les r?sultats des examens
biologiques sont attendus.

La surveillance syndromique ? partir du r?seau de m?decins sentinelles
va ?tre mise en place d?s le d?but du mois de janvier 2014. Une r?union
du Comit? d?experts pour les maladies infectieuses ?mergentes (CEMIE)
est pr?vue prochainement pour examiner les donn?es ?pid?miologiques
et proposer ?ventuellement un changement de phase du Psage.

Les mesures de surveillance renforc?e et de lutte antivectorielle
doivent se poursuivre et s?intensifier pour pr?venir la survenue de
cas secondaires et l?apparition de foyers et ainsi ?viter la diffusion
du virus.

Conclusions g?n?rales

L??pid?mie de Chikungunya poursuit sa progression sur l?Ile de Saint Martin.

La surveillance
? Saint Barth?lemy a ?galement mis en ?vidence des chaines locales de
transmission. Ces deux territoires sont plac?s au niveau 3a du Psage* : situation
?pid?mique.

En Martinique et en Guadeloupe, la confirmation biologique de nouveaux cas de
chikungunya autochtones confirme l?introduction du virus sur ces territoires. La
situation ?pid?miologique correspond ? la phase 2 du Psage* : transmission autochtone
mod?r?e. Les mesures de surveillance renforc?e et de lutte antivectorielle doivent
se poursuivre et s?intensifier pour pr?venir la survenue de cas secondaires et
l?apparition de foyers.

Pour la Guyane, la situation correspond toujours ? la phase 1 renforc?e du Psage du
chikungunya dont l?objectif est d??viter et/ou de contr?ler au plus vite l?instauration
d?une cha?ne locale de transmission du virus en mettant en place, sans d?lai, devant
tout cas suspect, probable ou confirm?, les mesures de contr?le adapt?es.

Current epidemiological situation in Martinique

Since early December 2013, the reinforced monitoring device
cases clinically suggestive based on the network of sentinel physicians
was estimated at 340 , the number of consultations in general practice
for suspected chikungunya . Over 65 % of these cases ( 220 ) have
been reported between 6 and 12 January . These data confirm
that virus circulation intensifies in the department .

Monitoring of probable and confirmed cases is carried out in close
collaboration with medical laboratories city , and hospital
Martinique and the CNR of arboviruses of the Pasteur Institute
Guyana and the CNR arboviruses the IRBA in Marseille. data
are still incomplete for the last weeks
Given transmission delays levies account. From now
already 127 confirmed or probable cases were reported by the monitoring
since the second week of December 2013.

The weekly number of cases clinically
suggestive of chikungunya seen in medicine
city ​​is on the increase in the
second and third week of January to
nearly 300 cases . In total, it could be
estimated from the sentinel physician network
that 655 cases clinically suggestive of chikungunya
were seen in general practice since
early December 2013 ( Figure 7).

Monitoring of probable and confirmed cases
is conducted in close collaboration with laboratories
Medical Biology city, and hospital
Martinique and the CNR of arbovirus
Pasteur Institute of French Guiana and the CNR
arbovirus of the IRBA in Marseille.

The weekly number
confirmed or probable cases follows the
same progression as the case clinically
suggestive , data of last week
is still incomplete in view of possible
transmission removal . 267 confirmed cases
or probable were reported by monitoring
since the second week of December
2013 ( Figure 8 ) .

January 30, 2014

The weekly number of cases clinically suggestive
Chikungunya seen in general practice has
increased further during the fourth week
January 2014. This growth , however, remains
moderate , 16 % compared to the level of
previous week.

In total, it could be estimated from the network
980 cases clinically as sentinel physicians
suggestive of chikungunya were seen in medicine
City since early December 2013 ( Figure 7).


The weekly number of confirmed cases or
likely tended to stabilize since mid -January.

This is due partly to the difficulties
Important encountered by laboratories
( CNRs and virology laboratory
CHUM) to analyze all samples taken
in general practice and other demand
that was made to healthcare professionals
Liberals do not routinely ask the
laboratory confirmation of chikungunya .

It is essential that this recommendation is
followed to book these analyzes to patients
actually requiring laboratory confirmation
Chikungunya (eg those with
risk factors) .

Since early December 2013 , 364 cases biologically
were reported positive by the system
surveillance ( Figure 8).

Since the beginning of the circulation of the virus , 29 cases
confirmed or probable chikungunya were
hospitalized more than 24 hours , six were
children ( 40 % ) .
Nine cases have been already classified , 2
severe and 7 non- severe forms (Figure
11); severe forms concerning persons
over 75 years with co -morbidities .

Current epidemiological situation in Martinique

The estimated number of cases clinically suggestive
Chikungunya seen in general practice during
fifth week of January 2014 indicates the
further increase the number of cases
recorded since the beginning of December 2013 ( Figure
7 ) . An increase of 34 % of the number observed
estimated clinically suggestive cases , seen in
Medicine city between the fourth and
fifth week of January.
Since the introduction of the device
monitoring in 1480 cases consulted a
GP grounds of suspicion of
chikungunya .

The number of biological confirmations chikungunya
weeks 2014-04 and 2014-05 , showed
lower , probably due to the change of
recommendations to prescribers
What technical constraints as well as known
CNRs and the virology laboratory of CHUM.
Since the establishment of biological monitoring ,
390 confirmed cases and 128 probable cases
been diagnosed ( and hospital ) (Figure 8). there is
essential that prescribers reserve the
analyzes in patients with factors
risk of developing as well as those forms
unusual disease .

Since the establishment of the monitoring device
in-hospital , 46 cases biologically
positive chikungunya were hospitalized more
24 hours of which 18 ( 39%) were
Children (<18 years).
In total, 20 cases have already been identified and
classified as non - severe forms and shapes in 3 cases
severe. Two of the three severe forms
involved patients aged over 75 years
with co - morbidities associated with infection
( Figure 11 ) .

The epidemic continued in Martinique with a 34% increase in the number of cases clinically suggestive of chikungunya
seen in the city between 2014-04 and 2014-05 weeks ( late January 2014).
The Martinique is still in Phase 3a of Psage : epidemic situation proved with local chains of transmission .

Current epidemiological situation in Martinique

The estimated number of cases clinically suggestive
Chikungunya seen in general practice during
first week of February indicates continued
increasing the number of cases recorded
since early December 2013 ( Figure 7). we
observed an increase of 18 % of the estimated number

Since the establishment of biological monitoring ,
844 confirmed and probable cases were diagnosed

Conclusions for Martinique

The epidemic continues in Martinique with a rising number of cases clinically suggestive of chikungunya
seen in the city between 2014-05 and 2014-06 weeks (early February 2014).

The Martinique is still in Phase 3a of Psage : epidemic situation proved with local chains of transmission .

Current epidemiological situation in Martinique

The estimated number of cases clinically suggestive
Chikungunya (887 cases) seen by doctors
general the 3rd week of February ( S2014 -
08) tends to stabilize over the week
previous . The development over the next
weeks will confirm or invalidate
this trend. From the first week of
December 2013 estimates based
weekly statements of doctors
sentinels were used to estimate the number 3940
of patients seen in the city
GPs for reasons of suspicion of
Chikungunya ( Figure 6 ) .

Since the introduction of the device Biomonitoring chikungunya in collaboration with the National Reference Centres
and Virology Laboratory , CHUM , 1058 cases were diagnosed for a confirmed or probable infection of chikungunya .
In addition, the recommendations of the new diagnostic strategy continue to target priority patients
risk factors as well as developing an unusual form of the disease , even in the current context characterized
by a shortage of diagnostic resources.

Since the establishment of the monitoring device
epidemiological intra hospital , a total
118 patients with laboratory confirmation for
chikungunya were hospitalized (over 24
hours ) . Of the total 83 patients classified
depending on the degree of severity, 71 (86% ) presented
not a severe form of the infection and 12 ( 14%)
developed a severe form of the disease.
In addition, 41 patients (35%) of the 118 patients
hospitalized less than 18 years ( Figure 9).
One person died in hospital and death
was assessed as being indirectly related to
infection .

The chikungunya epidemic continues in Martinique . The set of monitoring indicators reflecting a tendency
stabilization . Must await the coming weeks to confirm this trend.

The Martinique is still in Phase 3a of Psage : epidemic situation proved with local chains of transmission .
