Although acute-phase serum
from the patients reported here was almost always collected at the time of admission and those who had symptoms >7 days before admission were excluded from enrollment, for some, a rapid, anamnestic response could have developed before admission.
A total of 228 community case-patients in Springfield have been identified; 146 (64%) have had acute-phase serum
specimens tested at CDC by ELISA.
Paired, 2-week convalescent serum specimens are being obtained for the 18 patients (these 16 patients and the first two patients) whose acute-phase serum
specimens (three positive and 15 negative) have been tested.
Overall, 364 convalescentand unpaired acute-phase serum
samples were screened; 47 (12.9%), 104 (28.6%), 6 (1.6%), and 21 (5.8%) were seropositive for C.
([double dagger]) Acute-phase serum
samples from AFI patients were systematically tested for dengue by nonstructural protein 1 ELISA and IgM ELISA; convalescent-phase serum samples were also tested by IgM ELISA.
from case-patient 2 reacted with OspC for all Borrelia species included in the kit.
To determine whether humans were infected with WNV, we obtained acute-phase serum
samples within 1-7 days of onset of illness from persons visiting an outpatient clinic in Kashi during June 11-August 25, 2011.
In our retrospective study, we had only acute-phase serum
samples, but we performed PRNTs in an attempt to clarify the specific viruses causing severe disease in this region.
miyamotoi sensu lato DNA could not be amplified from any serum samples (including 27 acute-phase serum
samples) from the 52 participants who had test results positive for B.
Only acute-phase serum
samples were obtained from the other 6 patients.
samples, clinical information, and laboratory data for all patients given a diagnosis of SFTS in 2011 in Yiyuan County were submitted to the Yiyuan County Centers for Disease Control and Prevention.
