Worst whooping cough outbreak in over a decade 'likely to get worse' over summer

The massive whooping cough outbreak sweeping Scotland is likely to get worse over the coming months, an expert has warned. Dr Sam Ghebrehewet, head of immunisation and vaccination at Public Health Scotland (PHS), said infections would probably not peak until the autumn. It comes days after PHS revealed that a total of 2,232 laboratory-confirmed cases of pertussis - better known as whooping cough - had been detected in Scotland up to May 13.
