As with many other infectious diseases, big cities have experienced higher case counts and more rapid spread of the monkeypox virus – which causes the disease now known as mpox – than elsewhere in the U.S.

BCHC’s member cities have more than half the cases of mpox in the country.

Because of this, big cities need a share of the vaccines that is proportionate to their much higher need.

More information about mpox – including national and state-level data, signs and symptoms, prevention, treatment, and more – can be found on the CDC website.
