CDC's Tick Bite Data Tracker shows weekly emergency department visits for tick bites are currently above historical norms in most U.S. regions, with rates in all areas except the South Central U.S. at their highest for this time of year since 2017.

CDC is urging preventive measures ahead of Lyme Disease Awareness Month in May, citing risks of Lyme disease, Rocky Mountain spotted fever, and alpha-gal syndrome. Recommended actions include EPA-registered repellents, permethrin-treated clothing, and routine tick checks. Prompt tick removal — within 24 hours — is identified as a key intervention for reducing Lyme disease transmission. Read more from the CDC here.

CDC analysis published in MMWR reports a marked rise in extensively drug-resistant (XDR) Shigella infections in the United States. Among 16,788 isolates collected from 2011–2023, 3% were XDR, increasing from 0% in 2011–2015 to 8.5% in 2023.

Most cases occurred in adult men, with limited travel history, suggesting domestic transmission. XDR strains are resistant to five key antibiotics, and no FDA-approved oral treatments are available.

CDC highlights the need for strengthened surveillance, antimicrobial susceptibility testing, and rapid reporting, along with targeted prevention strategies to limit further spread and address growing antimicrobial resistance concerns. Read more in Food Safety Magazine here.

Individual and systemic racism affects virtually every aspect of public life. It is especially pervasive in medicine and public health. Being Black, indigenous, or a person of color (BIPOC) can be harmful to your health. 

The U.S. Congress and several local and state governments have declared racism a public health crisis. While these declarations are not legally binding, they convey that racial and cultural justice is necessary to safeguard all citizens’ health. Racism at individual and societal levels negatively impacts vulnerable populations’ mental and physical health. It also prevents members of marginalized groups from receiving equitable and adequate healthcare. 

Understanding why racism is a public health emergency can shed light on the health-related harms of racism and bigotry. It also stimulates efforts to remedy the injustices and improve the general health of all Americans. 

Why Is Racism a Public Health Emergency? 

A public health emergency occurs when the effects or consequences of a public health threat are pervasive enough to overwhelm the organizations and facilities responsible for responding to it. In most cases, policymakers and community leaders cannot legally enforce emergency declarations. Nevertheless, they serve as a call to action to review and revise current policies and practices that allow the emergency to permeate.
