hi Harry, all
they explain what they mean by "cases" and why / how they present
ranges, in this para:
Data from cases reported from 49 states, the District of Columbia, and
three U.S. territories (5) to CDC during February 12–March 16 were
analyzed. Cases among persons repatriated to the United States from
Wuhan, China and from Japan (including patients repatriated from cruise
ships) were excluded. States and jurisdictions voluntarily reported data
on laboratory-confirmed cases of COVID-19 using previously developed
data collection forms (6). The cases described in this report include
both COVID-19 cases confirmed by state or local public health
laboratories as well as those with a positive test at the state or local
public health laboratories and confirmation at CDC. No data on serious
underlying health conditions were available. Data on these cases are
preliminary and are missing for some key characteristics of interest,
including hospitalization status (1,514), ICU admission (2,253), death
(2,001), and age (386). Because of these missing data, the percentages
of hospitalizations, ICU admissions, and deaths (case-fatality
percentages) were estimated as a range. The lower bound of these
percentages was estimated by using all cases within each age group as
denominators. The corresponding upper bound of these percentages was
estimated by using only cases with known information on each outcome as
denominators.
