It depends on the citation format style you are using.
For example, if you are citing CDC material that you viewed on the organization's website and using the AMA style, you would cite the reference as a website, with "Centers for Disease Control and Prevention" as the corporate/organization author (see AMA Manual of Style, 10th ed., pages 51 and 68-69):
- Centers for Disease Control and Prevention. Screening for Critical Congenital Heart Disease at Birth Saves Lives. https://www.cdc.gov/media/releases/2017/p1205-screening-congenital-heart-disease.html. Accessed December 8, 2017.
There are a number of citation format styles (many, if not most, are journal-specific), so you may need to visit the journal's website and review the author guidelines. For APA style, see this FAQ: http://mdanderson.libanswers.com/faq/281746
