New York City’s health department has reported the first female-to-male transmission of the Zika virus, which is most typically spread by the bite of an infected mosquito.

Rory McIlroy says that telling Paul McGinley he was not going to compete at the Olympics was “one of the toughest phone calls I’ve had to make”.

Suspected links between the Zika virus and two neurological disorders, microcephaly in babies and Guillain-Barre syndrome, should be confirmed within weeks, the World Health Organization (WHO) said.

Men in the UK are being urged to wear condoms for a month after returning from any of the 23 countries affected by the Zika virus.
