We continue to get regular updates from the CDC about AFM.

CDC Telebriefing: Update on Acute Flaccid Myelitis (AFM) in the U.S.

Unfortunately, we aren’t getting the real answer we were looking for – how to stop the outbreak.

Acute Flaccid Myelitis Update

Since the last update, we have learned that:

  • the case count is up to 201 confirmed cases (up from 196 last week)
  • an additional 163 cases are under investigation (up from 161 last week)
  • cases have been reported in 40 states (up from 39 last week – Utah is the new state)

That means that we have clearly exceeded the last record of 149 cases in 2016.

There are also 47 confirmed cases and 29 cases (up 1) under investigation in Canada this year.

In other news:

  • the CSTE will be issuing issued a new statement on AFM reporting reaffirming that they “are confident state and local health departments are working closely with doctors to ensure suspected cases are reported.”
  • the CDC has posted updated treatment guidelines
  • an MMWR early release, Increase in Acute Flaccid Myelitis — United States, 2018,  will provide details on the first 80 cases of 2018 – but sound similar to what we have learned from outbreaks in 2014 and 2016…
  • the CDC is working with local and state health departments on better long term tracking of cases – something parents have been pushing for!
  • an AFM Task Force has been established to “bring together experts from a variety of scientific, medical, and public health disciplines to help solve this critical public health issue.”

Most importantly though, we again learned that the CDC still doesn’t feel that they have enough evidence to say that any one thing is causing AFM.

AFM Cases in the United States

In addition to this year’s cases, there were:

  • 33 confirmed cases in 16 states in 2017
  • 149 confirmed cases in 39 states in 2016
  • 22 confirmed cases in 17 states in 2015
  • 120 confirmed cases in 34 states in 2014 – with most of the cases being reported in California (24), Colorado (10), Utah (6), Massachusetts (9), Virginia (5), Indiana (5), and Illinois (4)
