Sera from an age-stratified sample of 1810 people from the Caribbean island of St. Lucia were tested for antibodies against varicella-zoster virus. The results indicate that very few infections occur in childhood which agrees with clinical survey data from other tropical countries, but contrasts with the observed high case rate in children in temperate countries. The alternative hypothesis which may explain these results are discussed, and it is suggested that high ambient tempertaures interfere with the transmission of the virus. Irrespective of the cause the pattern of varicella incidence observed has important implications for any vaccination policy adopted in tropical countries (AU)
