A self-test suffices for the diagnosis SARS-CoV-2 infection in the Netherlands since 11 April 2022. Yet, selected groups such as health care workers can still divert to the Public Health Services (PHS) SARS-CoV-2 testing facilities for a nucleic acid amplification test. A survey among 2257 subjects visiting PHS Kennemerland testing sites demonstrates that the majority of participants does however not belong to one of the selected groups.

Saliva could be a less invasive alternative for SARS-CoV-2 detection, but limited evidence is available.
Methods: The technical and clinical performance of saliva was compared to OP/NP on the Hologic Panther platform with two Aptima assays, the End-Point Transcription-Mediated Amplification assay (EP-TMA) and Real-Time Transcription-Mediated Amplification assay (RT-TMA).
Background: We assessed the association between severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) viral load and hospital admission, intensive care unit (ICU) admission, and in-hospital mortality.
Methods: All SARS-CoV-2-positive persons with a combined nasopharyngeal and oropharyngeal swab that was collected between 17 March 2020 and 31 March 2021 in public health testing facilities were included.
Results: From 20 207 SARS-CoV-2-positive persons, 310 (1.
Background: We assessed the SARS-CoV-2 reinfection rate in a large patient cohort, and evaluated the effect of varying time intervals between two positive tests on assumed reinfection rates using viral load data.
Methods: All positive SARS-CoV-2 samples collected between 1 March 2020 and 1 August 2021 from a laboratory in the region Kennemerland, the Netherlands, were included. The reinfection rate was analyzed using different time intervals between two positive tests varying between 2 and 16 weeks.
A 54-year-old woman presented with 2 weeks of fever after a trip to the Northeastern United States. Except for an erythematous skin lesion on her right shoulder, no physical abnormality was detected. We diagnosed concomitant borreliosis and babesiosis.

Intracellular tenofovir diphosphate levels were measured in 1 patient and were found to be very high, with plasma tenofovir levels just slightly elevated. Fibroblast growth factor-23, a phosphaturic hormone, was decreased in both patients and is therefore unlikely to have a pathophysiological role in this pathology.
