Real-Time Reverse Transcription–Polymerase Chain Reaction Assay for ...
Abstract A real-time reverse transcription–polymerase chain reaction (RT-PCR) assay was developed to rapidly detect the severe acute respiratory syndrome–associated coronavirus (SARS-CoV). The assay, based on multiple primer and probe sets located in different regions of the SARS-CoV genome, could discriminate SARS-CoV from other human and animal coronaviruses with a potential detection ...
Hospitalization Rates and Characteristics of Patients Hospitalized ...
The Coronavirus Disease 2019–Associated Hospitalization Surveillance Network (COVID-NET) was implemented to produce robust, weekly, age-stratified COVID-19–associated hospitalization rates.
Staying Up to Date with COVID-19 Vaccines | Covid | CDC
Importance of staying up to date Getting the 2026-2027 COVID-19 vaccine is important because: Protection from the COVID-19 vaccine decreases with time. Immunity after COVID-19 infection decreases with time. COVID-19 vaccines are updated to give you the best protection from the currently circulating strains. Getting the 2026-2027 COVID-19 vaccine is especially important if you: Never received a ...
Triplex Real-Time RT-PCR for Severe Acute Respiratory Syndrome ...
Abstract Most reverse transcription PCR protocols for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) include 2–3 targets for detection. We developed a triplex, real-time reverse transcription PCR for SARS-CoV-2 that maintained clinical performance compared with singleplex assays.

Symptoms of COVID-19 | CDC
COVID-19 is caused by infection with a coronavirus named SARS-CoV-2, and flu is caused by infection with influenza viruses. You cannot tell the difference between flu and COVID-19 by symptoms alone because some of the symptoms are the same. Some PCR tests can differentiate between flu and COVID-19 at the same time.
