The values of herd immunity against poliomyelitis virus type 3; they were lower than the required minimum in 2 towns and very low in 2 other towns arouse alarm.

[Use of multiplex PCR method with real-time detection for differential diagnosis of respiratory viral infections].

Multiplex real-time polymerase chain reaction test-system with fluorescent detection (RT-PCR) for simultaneous identification of main agents of acute respiratory viral infections: influenza A (IAV) and B viruses (IBV), parainfluenza viruses types 1, 2, 3, 4 (PIV 1 - 4), adenoviruses (ADV), respiratory syncitial virus (RSV), rhinoviruses (RV) and enteroviruses (EV), in presence internal positive control (IPC) represented by vaccine strain of rubella virus RA 27/3. Using multiplex RT-PCR method, respiratory viruses were detected in 116 out of 226 clinical samples (nasal swabs) obtained from patients with symptoms of acute respiratory infection: in 68 (58.6%) samples--IBV; in 21 (18.
