Duration of RT-PCR positivity in severe acute respiratory syndrome.
Severe acute respiratory syndrome (SARS) is a highly infectious respiratory infection with a high mortality. The duration of infectivity is unknown. The RT-PCR positivity for SARS-associated coronavirus (SARS-CoV) was followed in 45 virologically confirmed SARS patients. Serial RT-PCRs for SARS-CoV were performed in the nasopharyngeal aspirate, stool and urine of 45 SARS patients who survived u...
متن کاملSevere Acute Respiratory Syndrome–associated Coronavirus Infection
Whether severe acute respiratory syndrome-associated coronavirus (SARS-CoV) infection can be asymptomatic is unclear. We examined the seroprevalence of SARS-CoV among 674 healthcare workers from a hospital in which a SARS outbreak had occurred. A total of 353 (52%) experienced mild self-limiting illnesses, and 321 (48%) were asymptomatic throughout the course of these observations. None of thes...
متن کاملCoronavirus in severe acute respiratory syndrome (SARS).
In November 2002, an outbreak of a life-threatening ‘atypical pneumonia’ for which no etiological agent could be identified occurred in Guangdong Province, China. In March 2003, a similar outbreak was reported in Hong Kong [1]. Cases of similar respiratory illness were subsequently reported globally including China, Taiwan, Singapore, Vietnam, Canada and USA. This syndrome is a new clinical ent...
متن کاملA Multiplex RT-PCR Assay to Detect and Discriminate Porcine Reproductive and Respiratory Syndrome Viruses in Clinical Specimens
Outbreaks of highly pathogenic porcine reproductive and respiratory syndrome virus (HP-PRRSV) have led to large economic losses in China. The attenuated vaccine (HP-PRRSV JXA1-R) was used to control HP-PRRSV. However, in recent years, co-infection with classical PRRSV (C-PRRSV), HP-PRRSV, and/or HP-PRRSV JXA1-R has been increasing in China, resulting in a significant impact on PRRSV diagnostics...
متن کاملa novel sensitive multiplex rt-pcr elisa method for detection of hiv-1/hcv co-infection
objective: despite sensitive antibody based blood donor screening, infection can be transmitted during window period. therefore sensetive methods bosed on nucleic acid tests (nats) have been considered. the aim of this project was to design a more sensitive method for detection of pcr products and diagnosis of hiv-1/hcv co-infection accurately. materials and methods: after designing specific p...
