Hospitalizations

We focus on positive and suspected positive COVID-19 patients, as well as Intensive Care Unit (ICU) positive and suspected positive COVID-19 patients. From previous documentation, we assume that patients counts are defined as number of patients admitted the previous calendar day (need to verify)

“Suspected” are patients with out laboratory-confirmed COVID diagnosis who, in accordance with CDC’s Interim Public Health Guidance for Evaluating Persons Under Investigation (PUIs), have signs and symptoms compatible with COVID (most patients with confirmed COVID have developed fever and/or symptoms of acute respiratory illness, such as cough, shortness of breath or myalgia/fatigue).

The ICU counts represent the number of patients (either with confirmed or suspected COVID-19) in ICU beds (NICU, PICU, and adult) in the hospitals.

Note that these became available only at the beginning of April, so that we do not have records for the very beginning of the pandemic. Also note that the number of suspected cases is larger at the beginning of the pandemic–something that might be attributable of paucity of testing and lenght of turn around times.

With this in mind, we can look at the trend of daily hospitalization in California, for confirmed COVID-19 cases as well as suspected
