Infection by a given serotype induces a lifelong protective immunity against the homologous serotype
, but only a transient and partial protection against the three other serotypes (9).
Infection with a single serotype leads to long-term protective immunity against the homologous serotype
but not against other serotypes (1).
Invasive diseases may originate from nasopharyngeal colonization with the homologous serotype
Infection with 1 DENV serotype is believed to provide long-term immunity to the homologous serotype
but not to the other serotypes (2).
