You usually get symptoms 4 to 20 days after being infected. Symptoms include:
- runny nose
- sore throat
- generally feeling unwell.
In adults, symptoms can also include swollen, painful joints. These symptoms last for 2 to 3 days.
After a couple of days, a bright red rash appears on both cheeks. You can then get a pink, lacy-looking rash on your body, arms and legs. The rash usually lasts for 2 weeks but can come and go for 6 weeks.
When the rash has appeared, you are no longer infectious, but you can pass slapped cheek on for 5 to 6 days before the rash appears.

If you are pregnant
If you catch slapped cheek during the first half of your pregnancy, there is a small risk of miscarriage. There is also a small risk of your pēpi (baby) getting anaemia from low iron levels.
