↵* As of July 17, 2020.
↵† The numbers required are the total number of people (working a total of 8 h) in each work category needed per day to carry out all tasks contained in our 6-stage framework.
↵‡ For current strategy and strategy 1, 61%–68% of these health care professionals are nurses, 13%–14% are auxiliary (assistant) nurses, and 1%–2% are physicians. For strategies 2–5, 91%–98% of these health care professionals are nurses, 1% are auxiliary (assistant) nurses and 1%–3% are physicians.
↵§ This also includes a small proportion of data managers (1%–3%), with the high end of the range necessary when contact tracing is implemented.
↵¶ Categories included only if a change in human resource or laboratory capacity requirements occurred.
↵** Saliva sampling employed only for large-scale, prevalence-based testing programs in at-risk populations (strategies 2–5).
↵†† Combination of saliva and pooling samples.
