Introduction: Vaccination against varicella-zoster virus (VZV) has been effective and safe in countries that routinely administer the vaccine. Brazil began universal VZV vaccination in 2013. This study aimed to identify VZV genotypes present in Manaus, Brazil prior to widespread immunization. Methods: Vesicular lesions or cerebral-spinal-fluid samples were collected from patients diagnosed with VZV, herpes zoster, or meningitis/encephalitis. DNA was extracted, amplified, and sequenced. Results: Half the isolates were clade-5 viruses and the remaining were divided between the European clades 1 and 3. Conclusions: This study provides insights into the circulating VZV genotypes in Manaus prior to widespread vaccination.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
