The number of people diagnosed with HIV in the UK has dropped substantially since 2014, according to figures released by Public Health England.
Gay and bisexual men have experienced the most dramatic decline in new infections, with rates falling by 73%.

Of the estimated 103,800 people living with HIV in the UK in 2018, 93% have been diagnosed with the virus.

Among gay and bisexual men, transmissions of HIV have dropped from 2,300
