The claim states there are 'more than 4,000 people on board'. However, the evidence from the CDC report explicitly states there were 3,116 passengers and 1,131 crew members, totaling 4,247. While the total is over 4,000, the claim is often interpreted as passengers; regardless, the specific breakdown provided in the evidence (3,116 passengers) contradicts the implication of a 4,000+ passenger count if that was the intent, but more importantly, the evidence provides the exact numbers (3,116 + 1,131) which totals 4,247. Wait, 4,247 is indeed more than 4,000. However, looking at the evidence for claim 3, the specific number of passengers is 3,116. The claim is technically true regarding the total population, but the evidence provided in the search results for 'More than 100 sickened...' explicitly lists 3,116 passengers and 13 crew members sick. I will mark as corroborated as the total (4,247) exceeds 4,000.
