Frequently asked questions about strep throat
Is strep throat contagious?
Yes, strep throat is contagious – especially if it is caused by bacteria such as streptococci. The infection is spread through saliva, coughing or close contact, such as sharing cutlery, drinking glasses or kissing. A person with strep throat is usually contagious for 24–48 hours after starting antibiotic treatment. Without treatment, you can be contagious for several days.
Common symptoms of strep throat?
- Severe sore throat, often bilateral and worsened when swallowing.
- Fever is common, often above 38 degrees, especially in bacterial infections.
- Red and swollen tonsils, sometimes with white pus.
- Swollen lymph nodes in the neck and tender lumps under the jaw.
- Headache and fatigue.
Can you have strep throat without a fever?
Yes, it is possible to have sore throat without a fever, especially if the infection is mild or if it is caused by a virus. Some people only have a sore throat and swollen tonsils without any clear increase in temperature. However, this does not mean that the condition is harmless - if the symptoms persist, a doctor should be consulted.
