Introduction

Data Description

  1. This file displays trends in COVID-19 cases, deaths, and hospitalizations over time for different age groups.

  2. COVID-related counts are based on the PUI file extracted on September 30th, 2021. Only cases, deaths, and hospitalizations between 02/01/2020 and 09/26/2021 are included. Total population counts are taken from the 2020 OASIS Single Year of Age dataset. Data from persons with unknown age are excluded.

  3. COVID-19 cases include both confirmed cases and probable cases. Cases can be sequenced by date reported or symptom onset. Cases are reported through multiple sources including electronic lab reporting (ELR), State Electronic Notifiable Disease Surveillance System (SendSS), faxed case reports, and calls from providers to DPH. Only the first infection of each individual is included.

    • Confirmed Case: individual with a positive molecular test
    • Probable Case: individual who is antigen positive or with compatible illness and known close contact to a case
    • Date Reported: date the individual was marked as a case
    • Symptom Onset: date of symptom onset (date of positive specimen collection is used if symptom onset date is missing)
  4. COVID-19 deaths include both confirmed deaths and probable deaths. Deaths can be sequenced by date reported or date of death.

    • Confirmed Death: confirmed case that was either reported to DPH as deceased by healthcare providers or medical examiners/coroners, identified by death certificates with COVID-19 indicated as the cause of death, or there is evidence that COVID-19 contributed to the individual’s death
    • Probable Death: probable case that was either reported to DPH as deceased by healthcare providers or medical examiners/coroners, identified by death certificates with COVID-19 indicated as the cause of death, or there is evidence that COVID contributed to the individual’s death OR individual with a death certificate that has COVID-19 indicated as the cause of death and there is no laboratory evidence for SARS-CoV-2
    • Date Reported: date the individual was marked as a confirmed death or as a probable death
    • Date of Death: date the individual died
  5. COVID-19 hospitalizations include individuals who were hospitalized at the time the case was reported to DPH or when the case was interviewed. Only the first hospitalization of each individual is included. Hospitalizations are arranged by date of admission associated with the first hospitalization of an individual during COVID-19 infection (date the case was reported is used if date of admission is missing).

  6. Line plots show weekly COVID-related counts by the Monday starting the week and the corresponding rates (per 100,000 population). Where data is preliminary due to lag in reporting or incomplete weeks, dashed lines are used. To focus on particular age groups, click on the legend to remove unneeded lines. Stacked bar plots with counts and rates aggregated over calendar month are also provided for ages 17 years and below. Months with preliminary data have lighter bars.

  7. Tables compare this year’s data to data from one year ago. They include bar plots showing total COVID-related counts each week during the 14-week period 06/21/2021 to 09/26/2021 and the equivalent epiweeks from 2020, ordered by the Monday starting the week. Note, the y-axis for these plots may scale differently for different age groups, but is identical across the two years. Tables also contain rates (per 100,000 population) over three consecutive 14-day periods. If the total COVID-related count for an age group during a period is between 1 and 4, that rate will not be calculated and “<5 counts” will be displayed instead.
