Dr Williams, who is in the country for the All Africa Bishops' Conference, described his visit to the paediatric ward as "inspirational".Read the whole thing here - and please pray that it may remain open and serving the children.
But he was told that the unit, which has cared for thousands of the country's sickest children over the years, faces imminent closure as Mildmay International, the British NGO that runs it, cannot afford to do so for much longer. The 33-bed specialist HIV paediatric unit - known as Elizabeth Ward - is expected to close down in just 37 days when the existing funds run out.
Speaking after the visit, the Archbishop said: "It's been an inspirational experience this afternoon.
"I have seen how much real future is being offered especially to the children here, the generosity and imagination of the work - the quality of care is really wonderful to see.
"And of course when people see that there is hope like this, then it helps them to be honest about themselves and face their conditions.
"I really hope and pray there will be resource to keep this level of care, love and professionalism going on.
"I know that there are many problems that organisations like Mildmay face especially with the work of children and I really, really honestly want to see this work continue and hope that generous people will go out to support it.
"It is crucial for the life of this country and this continent."
