title: [Seroepidemiological surveillance of human parainfluenza viruses (HPIVs) types 2 and 3 in an infantile population selected in Havana City].
abstract: The presence of antibodies against human parainfluenza viruses type 2 and 3 was studied in 1 793 sera from an infantile population under 14 years old. The hemagglutination inhibition technique was used for screening the clinical samples. Of the total of analyzed sera, 1 382 (77.1%) were positive. The presence of antibodies against type 2 was confirmed in 320 of them (17.8%), and against type 3 in 334 (18.6%). The simultaneous seropositivity predominated in 805 (44.9%). The circulation of human parainfluenza viruses was corroborated during all the months of the year and in all the analyzed age groups. It was observed an increase in the positivity percentages with age.
