​The outbreak of the Corona virus is clearly a rapidly evolving situation. The organisers of the meetings listed below will be constantly reviewing the situation in the light of global and country-specific advice to inform decisions to minimise the additional risks to attendees, their communities and those living in the meeting’s host country.
