CDC-INFO is experiencing a very high number of calls and emails related to Coronavirus Disease 2019 (COVID-19; formerly named 2019 Novel Coronavirus or 2019-nCoV). Wait times for inquiries on all topics are longer than usual.

NOTE: if you submitted an inquiry between the dates of January 26 and February 6, 2020:

Due to extremely high webform inquiry volume, many inquiries submitted via the webform between January 26 and February 6, 2020, will not receive a reply from CDC-INFO. If you submitted an inquiry within this time period and you still need a response, please resubmit your inquiry through the webform or call CDC-INFO. We apologize for the delay and appreciate your patience as we work to respond to incoming inquiries as quickly as possible.

If you are a healthcare provider and your inquiry is urgent, please call instead of sending through the form.

If your inquiry is about COVID-19 and upcoming travel, please call instead of sending through the form.

If you have general questions about COVID-19, please consider visiting CDC’s Coronavirus Disease 2019 page instead. On our website, you can find the most up-to-date information on the outbreak and get the latest answers to frequently asked questions. You can also visit the CDC website for answers to questions on other health topics.
