Mike Coston at Avian Flu Diary has an excellent post today on PAHO Chikungunya Surveillance Update – June 13th, with not just the numbers but some insightful commentary. Excerpt:
The Chikungunya virus – which was only first reported in this hemisphere last December on the French Part of St. Martins - continues to spread across the Caribbean and make incursions into Central and South America at an impressive rate.
Two weeks ago (see PAHO Chikungunya Epidemiological Update – May 30th) the estimated number of cases had grown to just over 100,000 – today that number exceeds 165,0000.
As impressive as these growth numbers are, it should be noted that surveillance in some of the reporting nations is sub-optimal, and in some cases, reporting to PAHO lags behind by several weeks. Meaning the number of reported cases today is likely to be an undercount.
