Starting on 10 May HIFA is hosting a 'deep-dive' exploration on how to maintain essential health services: reproductive health, child health, mental health, non-communicable diseases, surgery, emergency care. Throughout we shall include a focus on vulnerable people as well as the general population. These explorations will unfold week by week over 6 weeks, guided by an expert working group of representatives of WHO and other organisations. The work is supported by WHO.
