Only 1 of the 7 patients from whom these samples were obtained was still positive by PCR at the first control visit 1 week later, but a signal was detected only with the NS-1 primer pair. A у8-fold increase between acute-and convalescent-phase serum samples was found in all 7 individuals with PCR-positive results (table 2). All 7 individuals with PCR-positive results had a у8-fold increase in antibody titers between serum samples collected during the acute and convalescent phases of the illness. In addition, 1 study participant with PCR-negative results also had a significant increase in antibody titer (patient 160; table 2). NPAs obtained from the 7 patients with RT-PCR-positive results at the first control visit 1 week after study entry also were tested.	./cache/cord-257521-1amcsgmj.txt	./txt/cord-257521-1amcsgmj.txt
