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.

“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.
