“Stop sneezing on me.”

January 28, 2025. The Trump administration has frozen communications from several federal health agencies.

Even if they unfreeze communications, they will likely politicize the reporting of data on infectious diseases like bird flu, COVID, and HIV. This will make it difficult for journalists to report on these issues and for citizens to assess their own risks and make decisions accordingly.

In the interest of transparency, I’m assembling a list of city and municipal agencies that provide health data. Scroll to the bottom for other organizations, like the WHO. I can’t vouch for the accuracy of each site, and some sites are easier to use than others. You’re going to have to do some digging. But at least you have a place to start.

I’m adding to the list as time allows. There’s a contact form at the bottom if you have questions or a link to add.

Update 2/19/2025. The CDC Bird Flu site is back up.

Update 2/28/2025. The installment of RFK Jr as Secretary of Health and Human Services will likely have a disastrous effect on public health in the US and beyond—which makes data transparency even more urgent.

As I’ve delved into health data websites, my understanding of the field has improved. Wherever possible, I’m focusing on three areas:

• General repositories of health data
• Respiratory virus surveillance
• Avian flu information (aka “bird flu,” H5N1)
