aDENV, dengue fever virus; MAC-ELISA, immunoglobulin M antibody capture enzyme-linked immunosorbent assay; PRNT, plaque reduction neutralization test; HI, hemagglutination inhibition test; ND, not done.
bPositive/tested.
cIn most cases, the serotype was determined only by serologic testing unless we indicate otherwise that virus isolation or polymerase chain reaction was also used. In many of these cases, the serotype could not be determined because of cross-reactions in serologic tests.
dSome samples were tested by one technique, and others were tested by two or more techniques; therefore, these numbers do not represent the total obtained by adding the rows.
