Can You Get Strep Without Tonsils? Symptoms + Treatment

If you’ve had your tonsils out, you might assume you can’t get strep throat — but that’s a common misconception. While tonsil removal does reduce the frequency of throat infections, it doesn’t eliminate the possibility of strep entirely.

Can You Get Strep Without Tonsils?

Yes — you can get strep throat without tonsils. Here is why:

• Strep throat is caused by Group A Streptococcus (GAS) bacteria, specifically Streptococcus pyogenes
• The bacteria infect the pharynx (back of the throat) — not just the tonsils
• When tonsils are removed (tonsillectomy), the tonsillar tissue is gone, but the posterior pharyngeal wall, soft palate, and other throat tissue remain
• Strep can still colonize and infect these remaining tissues

However, having had a tonsillectomy does typically result in fewer and less severe throat infections than before surgery. The tonsils are often the primary reservoir for strep; without them, infections tend to be milder and less frequent — but not impossible.

Strep Symptoms Without Tonsils

If you don’t have tonsils, strep symptoms may look slightly different than the classic presentation:

Symptoms That May Still Occur

• Sore throat — often less severe than pre-tonsillectomy strep
• Throat redness and swelling (of the pharynx)
• Fever (typically 101–103°F)
• Painful swallowing
• Swollen lymph nodes in the neck
• Headache
• Body aches
• Fatigue

Symptoms Less Likely Without Tonsils

• White patches or pus on the back of the throat — less likely without tonsillar tissue
• Severely swollen tonsils — obviously absent
• Throat completely blocked by swollen tonsils — less likely

How Is Strep Diagnosed Without Tonsils?

Without tonsils, a standard rapid strep test still works. The test involves a throat swab of the posterior pharynx (the back of the throat wall). The swab collects cells and secretions that may contain GAS bacteria, regardless of whether tonsils are present.

At CityHealth San Leandro:

1. A provider performs a throat swab — takes about 15 seconds
2. Rapid strep test results are available in 5–10 minutes
3. If the rapid test is negative but symptoms are strongly suggestive, a throat culture may be sent for more sensitive detection (results in 24–48 hours)
4. If positive, treatment is prescribed during the same visit

Strep Throat Treatment

Strep throat requires antibiotic treatment — it will not resolve on its own and can lead to complications (including rheumatic fever and kidney disease) if untreated. Treatment options:

• Amoxicillin or penicillin: First-line treatment — 10-day course for most adults and children
• Azithromycin (Z-Pak): Used for patients with penicillin allergy — 5-day course
• Cephalexin: Another option for penicillin-allergic patients

Symptoms typically improve within 24–48 hours of starting antibiotics. Complete the full course even if you feel better sooner.

Why Did I Get Strep Even After a Tonsillectomy?

If you’ve been getting strep repeatedly after your tonsillectomy, several factors may be involved:

• Household or school exposure: Close contact with someone who has strep (or is an asymptomatic carrier) is the most common cause of repeated infections
• Carrier status in household: Some people carry GAS bacteria without symptoms and can repeatedly transmit it to family members
• Environmental exposure: Shared water bottles, utensils, or towels with someone who has strep
• Residual tonsillar tissue: In rare cases, incomplete tonsillectomy leaves small tonsillar tags that can still harbor bacteria

Frequently Asked Questions

Can you still get strep throat after a tonsillectomy?
Yes. Removing the tonsils reduces but does not eliminate strep throat. The bacteria can still infect the back of the throat. However, strep infections are generally less frequent and less severe after tonsillectomy.

How do you test for strep when you don’t have tonsils?
A standard rapid strep throat swab still works after tonsillectomy. The swab is taken from the posterior pharynx (back of the throat wall). Results are available in 5–10 minutes at CityHealth.

How long is strep contagious?
Strep throat is contagious until you have been on antibiotics for 24 hours AND are fever-free. Without antibiotics, strep remains contagious for 2–3 weeks.

Is strep throat dangerous if untreated?
Yes. Untreated strep can lead to serious complications including rheumatic fever (which can damage heart valves), post-streptococcal glomerulonephritis (kidney inflammation), and rarely, a peritonsillar abscess (collection of pus in the throat). Always complete the full antibiotic course.
