Arizona Faces Highest Whooping Cough Cases Since 2015; Health Officials Urge Vigilance and Immunization

Arizona is experiencing the highest number of whooping cough (pertussis) cases since 2015, with 563 reported infections this year. This resurgence comes amid a national rise in pertussis cases, and health experts are closely monitoring the situation, especially as the bacterial infection poses a significant risk to infants and young children.

The Arizona Department of Health Services (ADHS) emphasized the importance of vaccination as the primary preventive measure. “Preventative actions taken during the pandemic likely reduced transmission, but as case numbers return to pre-pandemic levels, it’s crucial to continue using prevention methods,” said Nicole Witt, a spokesperson for ADHS.

Pertussis begins with mild, cold-like symptoms but quickly escalates to severe coughing fits that can last for weeks. Although adults may recover, infants and young children face a higher risk of serious complications like pneumonia and, in rare cases, death. Individuals who are unvaccinated or have weak immunity are particularly vulnerable.

ADHS urges residents to monitor for symptoms, stay home if sick, and practice good hygiene through regular handwashing. Vaccinations are available at healthcare providers, pharmacies, and public health programs. For more information on where to get vaccinated, residents can check their local health department or visit the ADHS blog.
