United States: A heartbreaking tragedy has struck Mississippi, as health officials confirmed the state’s first death from whooping cough in 13 years. The Mississippi State Department of Health revealed on Monday that the victim was a newborn less than two months old—too young to have received the protective pertussis vaccine.
From January 1 through September 29, 2025, Mississippi recorded 115 confirmed cases of pertussis. By comparison, all of 2024 saw only 49 reported cases, signaling a sharp rise in infections. State Health Officer Dr. Dan Edney reminded the public that Mississippi last lost infants to whooping cough in 2008 and 2012.
According to Edney, vaccination gaps are fueling this resurgence. “Mississippi consistently achieves high rates of infant and school-age immunizations, but adult participation is considerably weaker,” he explained during a press briefing. “When grown Mississippians fail to sustain their pertussis immunity, our infants become the most vulnerable,” according to the reports by mississippifreepress.org.
Whooping cough, formally known as pertussis, is a relentless respiratory illness that begins with nasal congestion and mild cold-like symptoms but quickly escalates to violent fits of coughing that can choke off breath. The signature “whoop” sound, often heard after a coughing spasm, gave the disease its notorious name.
Left unchecked, pertussis may torment an individual for two to eight weeks. In adults, it is often mistaken for a stubborn cold, but its contagious nature makes it a hazard. Infected individuals are urged to isolate for six to 21 days. “That cough doesn’t vanish quickly,” Edney cautioned. “And the longer it lingers untreated, the greater the danger.”
Treatment with antibiotics can shorten the illness and reduce its spread. For infants, however, pertussis can prove life-threatening because their tiny lungs are easily overwhelmed. “Often babies don’t even cough—they simply stop breathing,” Edney warned gravely.
Vaccination remains the strongest safeguard. The Tdap booster, offered from age seven onward, protects against tetanus, diphtheria, and pertussis, but immunity fades without regular renewal every decade. This makes adult boosters critical to shielding babies too young for vaccines. “Some vaccines grant lifelong immunity, like MMR,” Edney said. “But others, such as tetanus and pertussis, require consistent reinforcement,” as reported by mississippifreepress.org.
Expectant mothers are urged to receive the Tdap vaccine during the later stages of pregnancy, between 27 and 36 weeks, to pass protection to their unborn child. Families are also encouraged to limit a newborn’s exposure to crowds and visitors, especially during the first fragile six to eight weeks. After two months, infants may begin their DTaP vaccination series, which helps guard against whooping cough throughout early childhood.
“Pertussis is one of those illnesses where the vaccine is powerful, but not permanent,” Edney concluded. “To defend our youngest Mississippians, we must keep our community’s immunity strong.”
