Strep throat requires antibiotics to cure the infection and prevent complications. Without antibiotics, symptoms may persist for weeks and increase the risk of rheumatic fever.
Strep throat is caused by the bacterium Streptococcus pyogenes, or group A strep. Unlike viral infections, bacterial infections like strep don't resolve on their own. Antibiotics are necessary to kill the bacteria and shorten the illness duration.
Strep can affect different parts of the body, including:
The CDC states that untreated strep throat can lead to serious complications like rheumatic fever, which can damage the heart. Antibiotics reduce these risks and shorten recovery time from about 3-7 days to 1-2 days.
Common antibiotics prescribed for strep include:
Antibiotics are unnecessary for viral sore throats, which account for most cases. A rapid strep test or throat culture confirms whether the infection is bacterial. If negative, antibiotics won't help and may contribute to antibiotic resistance.
Symptoms of viral sore throat include:
Untreated strep throat can spread to household members and last 3-7 days longer. Complications like sinus infections, ear infections, or rheumatic fever are also possible. Antibiotics eliminate the bacteria within 24 hours, reducing contagiousness.
A 10-year-old child develops a sore throat, fever, and swollen lymph nodes. The pediatrician performs a rapid strep test, which comes back positive. The child is prescribed amoxicillin. Within 24 hours, the bacteria are gone, and symptoms improve within 1-2 days.
If untreated, the child's symptoms might persist for a week or longer, increasing the risk of spreading strep to siblings or classmates. The child could also develop complications like an ear infection or rheumatic fever.
Many people believe strep throat will go away on its own. However, unlike viral infections, bacterial infections require antibiotics to clear the infection fully. Others think antibiotics are always necessary for sore throats, but most sore throats are viral and don't need them.
Another myth is that natural remedies like honey or garlic can cure strep. While these may soothe symptoms, they don't eliminate the bacteria causing the infection.
Last winter, my daughter developed strep throat. Her pediatrician prescribed penicillin, and her symptoms improved within 24 hours. Without antibiotics, she likely would have been miserable for another week-and risked spreading the infection to her classmates.
Antibiotics are essential for treating strep throat. They cure the infection, shorten recovery time, and prevent complications. However, antibiotics aren't needed for viral sore throats, which are far more common. Always consult a healthcare provider to determine the cause of a sore throat before deciding on treatment.
