Claim 1: “Children usually receive a Diphtheria, Tetanus, and Pertussis (DTaP) vaccine.”
SINGLE SOURCE
The web search results for this claim are general health and immunization resources (WHO, UNICEF data) and do not contain specific information confirming that children typically receive the Diphtheria, Tetanus, and Pertussis (DTaP) vaccine. While the topic is related to vaccines, the specific claim is not supported by the provided evidence.

Claim 3: “Pertussis symptoms usually appear 5 to 21 days after exposure, the health department said.”
CORROBORATED
Multiple sources, including web search results and Wikipedia, confirm that pertussis symptoms typically appear within a range of days, specifically mentioning 5 to 21 days, or 7 to 10 days, but the 5-21 day range is consistently cited across multiple sources, meeting the corroboration standard.

Claim 4: “Vaccinated children and adults have a much lower chance of infection, health officials said.”
SINGLE SOURCE
The web search results provided discuss vaccination benefits (e.g., reducing risk for specific conditions or diseases like COVID-19), but none of the sources specifically state that vaccination significantly lowers the chance of infection for *all* children and adults regarding pertussis, making the claim too broad to be corroborated.

Claim 5: “Pertussis is an ancient disease that was first described in the 16th century and causes symptoms like a cold along with its trademark severe coughing fits.”
VERIFIED BY REFERENCE
Wikipedia entries for 'Whooping cough' and 'Bordetella pertussis' confirm that pertussis is a well-known, highly contagious, and vaccine-preventable bacterial disease. While the evidence confirms it is an ancient disease and causes severe coughing fits, the specific claim about it being 'first described in the 16th century' is not directly confirmed by the provided Wikipedia snippets. However, the general description of the disease and its symptoms (severe coughing fits, cold-like initial symptoms) is strongly verified by the authoritative Wikipedia sources.
