Prevalence of human calicivirus infection in Kenya as caliciviruus by enzyme immunoassays for three genogroups of the virus. These results suggest the non-circulation of both rotavirus and calicivirus within the Maternity Hospital.

Seroprevalence studies suggest that HuCV infections occur in early childhood, especially in developing countries [ 23 ]. Como controles positivos se incluyeron muestras fecales de infantes previamente probadas positivas para rotavirus.
