What is the difference between the “Nationwide Weekly Molecular Detection of Respiratory Pathogens” and the “Weekly Trend of Positive Specimens for Designated Respiratory Pathogens Reported via the Laboratory Automated Reporting System (LARS)” trend charts?
Both systems are laboratory-based surveillance platforms aimed at monitoring the activity of important respiratory pathogens. However, they differ in specimen sources, testing methods, reporting timeliness, etc. These systems complement each other as part of a multi-source surveillance approach to enhance sensitivity. Interpretation of trends should be made in conjunction with various surveillance indicators for a comprehensive assessment of the epidemic situation.
NHIA historical data has been modified starting from March 13, 2025
Due to practical needs, the age stratification method of the NHIA data has been adjusted. Starting from March 13, 2025, the NHIA data will be reprocessed. As a result, historical health insurance consultation data has been modified since 2016.
Description of the “Nationwide Weekly Respiratory Pathogens/Influenza Virus/Enterovirus Detection”
The source of data on pathogen detection is from Contracted Virology Laboratories surveillance. Before 2024 (inclusive), the laboratories adopted the testing method of virus isolation, culture, and identification. Since 2025, the testing method has been adjusted to molecular detection; therefore, the results from these two methods will be presented separately.
What SARS-CoV-2 variants are currently being monitored?
1. The trend chart includes variants classified by the World Health Organization as current or former variants of interest (VOI), variants under monitoring (VUM), key domestic variants, and others (e.g. recombinant variants).
2. In the future, variant information may be adjusted due to factors such as the inclusion of new variants by the WHO, reclassification/renaming of variants, or the need for enhanced monitoring.
