Cannot rule out person to person spread, says WHO
Guenael Rodier, the WHO's head of communicable diseases and response, said experts cannot rule out person-to-person infection because "we haven't documented each and every case properly".
"When you have a mother and a child, and both get sick, you don't know if they both were exposed to the chickens or if the mother got sick because she was caring for the child," Rodier said. "It leaves room for some question marks. We have not documented every transmission story."
