CHIKV in CARPHA Countries

Table 1. CHIKV in CARPHA Countries

CARPHA is the regional agency for public health established by CARICOM. It addresses the 'surveillance and management of communicable diseases', and it currently tracks Chikungunya (CHIKV) cases in the twenty CARICOM countries and thirteen other countries in the Americas. Table 1, at left, shows the current situation with regards to Chikungunya cases recorded in these thirty-three (33) countries. Reports by CARPHA for individual countries can be (is presently) different from reports by PAHO/ WHO. This page provides a reusable tabulation of CARPHA reports and interactive maps and charts.

Confirmed/ Probable cases are those with a positive result for one or more laboratory tests (IgM ELISA, viral isolation, RT-PCR or 4-fold increase Chikungunya virus specific antibody) - extracted from CARPHA Case Definitions published in CARPHA Chikungunya Updates.

The number of cases reported by CARPHA for some countries can be (is presently) very outdated.

Chart 3. Reliability of CARPHA Reports

The number of new cases of Chikungunya per day (the average for a week) may be declining, from a high of over 12,000 new (confirmed/ probable or suspected) cases in July 2014. However, as noted above, the reports published by CARPHA are very outdated for some countries and therefore are not fully reliable.

Chart 4. CARPHA Countries New Cases/ Day


It seems that not all Chikungunya cases are or can be confirmed by laboratory tests. 'Suspected cases' in simple terms, are those with notable symptoms e.g. fever and severe pain in a joint(s), not explained by other medical conditions. The total cases includes the confirmed/ probable and the suspected cases. The total number of cases continues to rise throughout the Region. However, as noted above, the reports published by CARPHA are very outdated for some countries and therefore the current total cases may be an underestimate.
