Like all herpesviruses, cytomegaloviruses (CMVs) code for many immunomodulatory proteins including chemokines. The human cytomegalovirus (HCMV) CC chemokine pUL128 has a dual role in the infection cycle. On one hand, it forms the pentameric receptor-binding complex gHgLpUL(128,130,131A), which is crucial for the broad cell tropism of HCMV.

- Rapid antigen tests (RATs) have been widely adopted since autumn 2020 to quickly identify SARS-CoV-2 infections, especially amidst the rise of the omicron variant.
- A study evaluated nine RATs using respiratory samples, finding that omicron required significantly higher virus loads to test positive compared to the delta variant.
- The study highlighted a concerning decrease in true positive rates for omicron samples, emphasizing the need for improved detection strategies and a list of effective RATs during the ongoing pandemic.
Successful containment strategies for the SARS-CoV-2 pandemic will depend on reliable diagnostic assays. Point-of-care antigen tests (POCT) may provide an alternative to time-consuming PCR tests to rapidly screen for acute infections on site. Here, we evaluated two SARS-CoV-2 antigen tests: the STANDARD™ F COVID-19 Ag FIA (FIA) and the SARS-CoV-2 Rapid Antigen Test (RAT).
