Sore throats and flu symptoms are some of the most common reasons children come to our clinic.
Common Questions
Strep throat can be much more serious than a sore throat. If left untreated, it can cause problems with the kidney and cause heart problems. Most younger children with strep throat have a fever and severe sore throat, while older children may only have a sore throat. Occasionally, a rash can accompany Strep Throat.
Many children will have swollen red tonsils with white or yellow spots, along with tiny red spots on the roof of their mouth. Some children will only have a stomachache, swollen lymph nodes or a rash. A Strep test is the only way to diagnose with certainty. The Rapid Strep Test at After Hour Pediatrics is 97% sensitive and provides results in 15 minutes.
Your child is contagious for 18 to 24 hours after starting antibiotics. After Hour Pediatrics can provide the first dose at the clinic to prevent to spread to family members and ensure a rapid return to school.
Influenza or “Flu”
The flu is a highly contagious respiratory illness caused by influenza viruses. It can cause mild to very severe symptoms. Serious outcomes of flu infection can result in hospitalization or death. Some people such as senior citizens, young children and people with certain health conditions are at high risk for serious flu complications. The best way to prevent the flu is by getting vaccinated each year.
Common Questions

A: After Hour Pediatrics can perform a Rapid Flu test in the office with results in 20 minutes. During the coronavirus pandemic, we suggest checking for COVID-19 as well. Both rapid tests can be performed with one nose swab.
Yes. Flu can be treated with an antiviral medicine called Tamiflu. Tamiflu works only if started within the first 48 hours of flu symptoms so come in quickly if you suspect influenza. Young children and those with underlying medical conditions such as asthma should be treated.
