Does WHO recommend screenings at country entry and exit points to detect if ill people are travelling?
No. WHO does not believe entry and exit screenings would work to reduce the spread of this disease. However country-level measures to respond to a public health risk are the decision of national authorities, under the International Health Regulations 2005. Countries that adopt measures that significantly interfere with international traffic (e.g. delaying an airplane passenger for more than 24 hours, or refusing country entry or departure to a traveller) must provide WHO with the public health reasoning and evidence for their actions. WHO will follow up with all of its Member countries on such matters. Travellers should always be treated with dignity and respect for their human rights.
