Pertussis (whooping cough), COVID-19, seasonal influenza (flu), and respiratory syncytial virus (RSV) are currently circulating in New York City.
Nationally, there have been more than five times as many pertussis cases in 2024 compared with the same period in 2023, which includes increases across New York City.
COVID-19, flu, and RSV typically increase during the late fall and winter months, but timing can vary.
Pertussis does not have a definitive seasonal pattern.
The table below summarizes diagnosis, treatment, and prevention guidance for these common respiratory pathogens.
Timely assessment is critical to prevent severe outcomes from pertussis, COVID-19, flu, and RSV. Infections with these respiratory viruses can be difficult to distinguish based on clinical symptoms alone. Diagnostic tests are available to guide clinical decision-making and appropriate treatment for people with clinically compatible symptoms or a recent exposure. Diagnostic tests should be considered regardless of an individual’s vaccination history.
Treatment can prevent progression to severe disease from pertussis, COVID-19, and flu. Treatment is especially important for people with circumstances or conditions that put them at higher risk of serious complications (eg, infancy, older age, frailty, immuno-compromise, pregnancy, and chronic medical conditions).
Immunization against pertussis, COVID-19, flu, and RSV remains the best way to protect people against severe disease. Assess all individuals for their vaccination status at every office visit using your electronic health record and the Citywide Immunization Registry. Strongly recommend vaccination and co-administer vaccines whenever possible.
