 One health requires a multi-sectoral approach because the diseases which we work on affect multiple sectors. So a disease like rift valley fever for example affects animals, it also affects people. And so you need all these sectors to come together for such diseases to be better managed. The diseases which require one health approach are complex and they affect several sectors including agriculture, human health, environment. And that's why you need multiple sectors, you need various professionals to come together, including medical professionals, veterinarians, ecologists to combine efforts in understanding how these diseases are transmitted between these sectors. Let's use rift valley fever as an example to demonstrate why we need a multi-sectoral approach. A disease first starts affecting livestock before it jumps to humans. So in that sense you need all these sectors to share information on how the diseases occurring. For example let's consider in 1996-97 outbreak of rift valley fever. Up to 20,000 people affected and slightly over 100 died. But 10 years later in 2006-07 only 700 cases were reported. It doesn't really strongly show any impact but between 1996 and 2007 Kenya developed a one health approach to zoonotic diseases. And that enhanced the response sharing of information as well as implementation of management measures. So in a natural one health approach helps in motivating or in enhancing response and surveillance as well as implementation of disease control measures. So actions which are required to strengthen one health is basically to change our approach. We need to change from focusing on disease control to prevention. And that requires changing culture, changing partnerships arrangement, changing how we plan for disease control. We can cite at least two key actions that are required. One is mainstreaming one health right from the national sub national to community levels to help in developing a coordination plan between communities, between professionals. The other one is building a one health workforce which then takes over the implementation of one health interventions.
