So many modes of transmission come into play in close, overcrowded, indoor environments, and people need to understand and manage their risk in these situations, said Dr. Mike Ryan, executive director of the World Health Organization's Health Emergencies Programme.
“It is important, as I’ve said previously, that governments communicate those risks very, very carefully. And it is also important that providers, authorities and others ensure that those environments are as safe as possible, and that those risks are also managed,” Ryan said during a WHO media briefing in Geneva on Friday.
While the best combination of interventions remains unknown, Ryan said that if individuals and communities are aware of the risks – and authorities take actions to ensure safety in places such as schools, buildings and restaurants – countries can control the virus.
“It’s not one thing,” Ryan said. “It is a combination of measures in which the community, in partnership with each other and in partnership with the authorities, come to a sustainable way of controlling and suppressing the transmission of the virus, and living with the virus in a way that normal human activity can resume in a successful way.”
Science continuing to understand human transmission and how it happens is very important for this, as it will help to ensure how the measures being put into place need to be adapted, he said.
