Figure. Timeline and extent of product and molecular diagnostic contamination issues in 10 laboratories in Europe during delayed laboratory response to COVID-19. A) Contamination status of commercially ordered primers and probes for molecular detection of SARS-CoV-2 based on Corman et al. (2). Red vertical dotted line indicates starting date of laboratories in Europe receiving contaminated commercial primers and probes. The letters a–h are unique identifiers for the 8 companies that produced the materials. B) Timeline of simultaneous hallmark events in the SARS-CoV-2 outbreak. C) Delay of implementation of SARS-CoV-2 diagnostic test in laboratories and delay of national or regional roll-out schemes per laboratory. Laboratories that indicated no delay had access to noncontaminated material from previous orders or cooperated with another laboratory.
