Health officials urge Missourians to protect against respiratory illnesses

As respiratory illness season begins, health officials are urging Missourians to protect themselves and their loved ones from various respiratory illnesses, including influenza (flu), respiratory syncytial virus (RSV), and pertussis (whooping cough). Vaccination remains a critical tool in preventing illness, reducing severe symptoms, and protecting communities.

Each of these illnesses can spread rapidly and lead to severe health outcomes, particularly for pregnant individuals, those with underlying health conditions, young children, and older adults. Health officials emphasize that vaccination, combined with preventive measures, offers robust protection.

Influenza (Flu)

The flu vaccine reduces the risk of severe complications and hospitalizations. This year’s vaccine targets the strains predicted to circulate widely during the 2024-2025 flu season. The Centers for Disease Control and Prevention (CDC) recommends that everyone aged 6 months and older receive the updated flu vaccine.

Dr. Heidi Miller, chief medical officer with the Missouri Department of Health and Senior Services (DHSS), noted the overlap between flu risks and chronic health conditions. “The risk of heart attack is six times higher during the week after a flu diagnosis,” Miller stated.

Missouri’s flu dashboard, updated weekly, provides state and county-level data.

Respiratory Syncytial Virus (RSV)

RSV can cause severe respiratory infections, particularly in infants and older adults. Vaccines are now available for older adults, pregnant individuals, and high-risk infants.

RSV typically spreads from October through March. Health officials recommend immunization for:

• Adults aged 75 and older.
• Adults aged 60-74 are at increased risk.
• Pregnant individuals 32-36 weeks pregnant between September and January.
• Infants younger than 8 months.
• High-risk children aged 8-19 months.

RSV vaccines require a prescription from a healthcare provider.

Pertussis (Whooping Cough)

Pertussis, caused by bacteria, is highly contagious and especially dangerous for children. Vaccination schedules for pertussis include:

• DTaP for infants and young children.
• Tdap for adults, adolescents, and pregnant individuals during the third trimester.

Missouri has reported a significant rise in whooping cough cases in 2024, with a decline in vaccination rates among kindergartners. Early diagnosis and antibiotic treatment can reduce the contagious period for infected individuals.

Preventive Measures

Health officials recommend the following steps to reduce the spread of respiratory illnesses:

• Wash hands regularly with soap and water.
• Clean frequently touched surfaces.
• Cover coughs and sneezes with a tissue or elbow.
• Stay home when feeling unwell.
• Get adequate sleep to boost immunity.
