But only three of these passengers were later found to match with the 26,182 patients with COVID-19 reported to California by April 15.This suggests the efforts, despite requiring 1,694 person-hours of work, were a near-complete failure.&quot;The benefits of screening for case detection at the airport might be limited for a respiratory disease with the potential for presymptomatic and asymptomatic transmission, such as COVID-19,&quot; the reports&#x27; authors wrote.By contrast, airport screening for Ebola during the 2014-15 outbreak was more effective because the disease &quot;has obvious clinical manifestations, is contagious only after symptom onset, and a smaller number of travelers required monitoring,&quot; the report added.According to the USA TODAY report, the White House is seeking to revive the policy of checking travelers for fever at 20 US airports.Trump&#x27;s chief of staff Mark Meadows said the effort would be visible and instill confidence in travelers, according to meeting notes cited by the newspaper.But Martin Cetron, the CDC&#x27;s director of global mitigation and quarantine, pushed back, the newspaper said.&quot;Thermal scanning as proposed is a poorly designed control and detection strategy as we have learned very clearly,&quot; he wrote in an email to Department of Homeland Security officials.&quot;We should be concentrating our CDC resources where there is impact and a probability of mission success.&quot;The mooted plan would see passengers with fever referred to the CDC, with Cetron questioning the agency&#x27;s authority to execute this plan.He ended his email: &quot;Please kindly strike out CDC from this role.&quot;<div>© Agence France-Presse</div>
