Outbreak Prevention and Response: Disease Statistics

How to Report Illness
Outbreak Investigation Procedures

In order to identify an outbreak, it is important to monitor the amount of illness within the community. When the number of sick people increases above normal, public health professionals work to control and prevent the spread of illness until the outbreak is over.

Local Illness Numbers
Some diseases are required by law to be reported to the Southern Nevada Health District as soon as they are diagnosed by health care providers. The Health District collects all of this information and posts the data here for public access. The common foodborne illnesses, such as salmonellosis caused by Salmonella, are organized under the heading “Enteric Diseases.” You can compare the numbers of illnesses from month to month or year to year. Please note, norovirus is not a reportable illness so the Health District cannot and does not track norovirus cases.


National Illness Numbers
For national numbers, the Centers for Disease Control and Prevention (CDC) tracks the number of outbreaks reported by each state through the National Outbreak Reporting System (NORS). On their NORS Dashboard, you can view outbreaks occurring across the nation and customize the map based on type of outbreak, time period, setting, and more. View the NORS Dashboard here.
