Both sites support multiple languages (English and Spanish), and both include lang="es" on the element of the Spanish pages. However, on the CDC site, in addition to lang="es" the element has xml:lang="en". This potentially sends mixed messages to screen readers (is this web page in Spanish or English?) JAWS 13 seems to honor lang rather than xml:lang but I don't know about other screen readers.
The DOJ is currently working to release new technical standards for digital accessibility. The latter updates to the ADA guidelines will be in conjunction with the latest version of WCAG 2.1, which includes the most widely accepted digital accessibility requirements across the globe. If organizations want to overcome the current limitations of ADA guidelines, then they should follow the WCAG 2.1 checklist,11 as well as the suggestions provided by the ADA. The latter two steps, combined with the help of a trusted digital accessibility compliance platform,12 can help organizations achieve digital accessibility best in class standards throughout all of their digital formats and across all media.
You can test specific themes for compliance with these guidelines using a tool such as the WAVE Web Accessibility tool.  For sites that require 100% compliance, we recommend testing your theme of choice using the demo page for the theme, for example Twenty Fourteen. We also recommend using Header Text (displaying the Site Title), rather than a Header Image, as some themes will not provide AltText and therefore generate an error in the accessibility tool when a Header Image is set.
Since March 15, 2012, ADA compliance with the 2010 Standards will be required for new construction and alterations. In the period between September 15, 2010 and March 15, 2012, covered entities may choose between the 1991 Standards ADA Compliance (without the elevator exemption for Title II facilities), the Uniform Federal Accessibility Standards (Title II facilities only), and the 2010 Standards ADA Compliance.

Again using the WAVE toolbar, check for Errors, Features, and Alerts. If there are many errors, I assume this page will not serve as a good example, and stop checking. If there are only a few errors (e.g., fewer than five) I'll check those errors and might be forgiving if they're relatively minor and are offset by good accessibility in other areas.
As a web developer, Ryan's work is what makes the magic happen. He spends most of his time creating custom websites, which involves turning the designers' visual mockups into code. It's lucky that he's such a good problem solver, because many of Ryan's projects involve working with clients to create complex custom functions. He's also one of the few developers in the country with extensive experience developing for the HubSpot CMS.
I should mention one caveat to all of this. Businesses that are required to comply but don't have the ability to bring their websites into compliance can provide an accessible alternative to provide the same information, goods, and services that they provide online, like a staffed phone line. The trick, however, is that this option has to provide at least equal access, including in terms of hours of operation. And, as we know, the internet is around 24/7, so good luck with that. 
Is your website accessible to ALL users? The Americans with Disabilities Act (ADA) of 1990 prohibits discrimination based on disability. Legal precedent has now evolved to include new forms of technology and communication under the act – like websites. ADA compliance for websites will be federally regulated come 2018! Find out more about the new ruling and what you could be doing to prep your website for these accessibility requirements.
...the full and equal enjoyment of the goods, services, facilities, or accommodations of any place of "public accommodation" by any person who owns, leases, or operates a place of public accommodation. Public accommodations include most places of lodging (such as inns and hotels), recreation, transportation, education, and dining, along with stores, care providers, and places of public displays.
