If it's measles there's a cough
I refer to the article 'Are there any sure signs of measles?' (Answerback, February 24).
I witnessed a measles outbreak in our practice in the late 1980s, immediately prior to the introduction of MMR vaccine.
It is important to realise that measles is primarily a respiratory infection, with coryza, conjunctivitis and cough.
The presence of cough is particularly useful in distinguishing measles from other viral rashes.
To quote Nelson's textbook of paediatrics: 'The diagnosis of unmodified measles should not be made in the absence of cough.'
