Hawke's Bay District Health Board is warning that rates of syphilis are on the rise.
The DHB is running a social media campaign titled Syphilis. It's back. Get tested. Get treated to warn people about the sexually transmitted infection.
The DHB's medical officer of health, Rachel Eyre, said more cases were being reported nationally, so it was important people understood exactly what syphilis was and how to avoid infection.
"While local cases remain low compared to other regions, it is important sexually active people are aware of the infection and the serious health issues it can cause if not treated."
"Syphilis is a bacterial infection that is treated with antibiotics and prevented through practising safer sex. If left untreated it can cause damage to vital organs or harm unborn babies with potentially fatal complications for a foetus exposed to syphilis."
