DAILYMAIL.CO.UK - Nov 26 - Dr Peter Greenhouse, a Bristol doctor, warned Internet porn is contributing, too. Young people using Tinder could soon trigger a surge in HIV cases because they're more likely to change partners regularly. The NHS has already seen a rise in more treatable infections, which some experts have pinned on the rise of dating apps. But despite the fear of spreading cases, the number of people being newly diagnosed with HIV in the UK is at its lowest level in 18 years. Data released by Public Health England in September revealed just 4,363 people in the country were diagnosed in 2017. This was far lower than a spike in 2005 which saw nearly 8K people diagnosed.
