County Response Timeline
Since August, the county has been working with the Virginia Department of Health (VDH) and the Centers for Disease Control (CDC) to determine the appropriate steps needed to mitigate the issue with the cooling towers from arising again. The following are the schools with cooling towers that tested positive for legionella between the time frame of July 14 and August 20:
- Greenfield Elementary
- Midlothian Middle
- Falling Creek Middle
- L.C. Bird High
- Hopkins Elementary
- Alberta Smith Elementary
- Matoaca High
All cooling towers at schools were cleaned and treated with chemicals when legionella was found. As part of the Health Department's investigation, other county facilities were visited, and officials determined no further action was needed at those facilities.

Statement released from Chesterfield Health District Director Dr. Alexander Samuel:
There have been 14 cases of Legionnaires' disease confirmed in Chesterfield county for 2019. The two most recent cases had dates of disease onset near the end of August and the end of September. Both were confirmed by VDH staff in September and early October, respectively. The last case associated with the cluster patterns that prompted the VDH investigation was noted on 7/19/19, bringing the total number of cases at that point to ten. The four cases since 7/19/19 have been individual, isolated cases. None of these occurred within the areas of concern that were the focus of the investigation and none are closely associated with each other in time or geographic area. We expect to see additional individual, isolated cases because health care providers are testing more routinely for Legionnaires' disease now.

The Virginia Department of Health (VDH) released the following statements to media in response to confusion on the number of Legionnaires’ cases and who has contracted the disease:
- VDH is investigating an unusual cluster of cases of Legionnaires’ disease in the Chesterfield Health District: Twelve cases since May 2019. Thus far in this investigation, Chesterfield Health District has no reports of students, staff or parents in any CCPS school having contracted Legionnaires’ disease within Chesterfield County. Thus far in this investigation, there is no link between any CCPS school and those who have contracted Legionnaire’s disease.
- Regarding reports of illness prior to May 2019, there was - and is - no information necessary to share to protect public health, beyond the known precautions for Legionnaires’ disease. Thus, no further information is available.
- VDH's top two priorities – in order – are protecting public health and protecting patient privacy. VDH is further bound by the Health Insurance Portability and Accountability Act (HIPAA), which prohibits disclosure of potentially identifying patient information, unless such disclosure is necessary to protect public health. Patient information – including any potentially identifying info, including locations such as place of employment - is only disclosed when necessary to protect public health.

The Department of Risk Management provides a summary of the testing and cleaning of cooling towers.
- 45 towers at 31 schools were tested for the presence of legionella bacteria following disinfection and cleaning. Out of 45 cooling towers, three tested positive (7%). This included one tower each at Matoaca High School, L.C. Bird High School and Alberta Smith Elementary School.
- Since that testing occurred and after additional cleaning at all three cooling towers, follow-up testing has been performed. The results for all three schools are negative.
- Two cooling towers at Cosby High School have not been tested. The Cosby High School cooling towers are not operating and are down for repairs.
- The CCPS Facilities division is planning to go through the Centers for Disease Control and Prevention (CDC) startup protocol for these cooling towers when they become operational again. Subsequent testing will follow protocol.

VDH Sends News Release
The Virginia Department of Health sends a news release that stated the Chesterfield Health District (CHD) is investigating an increase in cases of Legionnaires’ disease associated with the northeast quadrant of Chesterfield County. Since May 1, there have been 10 confirmed cases among older adults and persons with other medical conditions. The CHD is working with the Centers for Disease Control and Prevention (CDC) to identify possible sources of exposure to Legionella. If any sources are identified, CHD will recommend strategies to stop the spread of Legionella. Investigations into increased cases of Legionnaires’ disease are complex. It is often not possible to determine the origin of the bacteria that infected people. The investigation is currently aimed at ruling out possible sources.
