Strep Throat Recovery: How Long Off Work?
Strep throat (Group A Streptococcal pharyngitis) is different from a viral sore throat in one critical way: it requires antibiotics, and you remain contagious until you've been on antibiotics for at least 24 hours.
Recovery Timeline with Antibiotics
| Timeline | What to Expect | Work Status |
|---|---|---|
| Day 1 (diagnosis) | Severe sore throat, fever, swollen glands | Cannot work — start antibiotics |
| Day 2 (24 hrs on antibiotics) | Still painful but no longer contagious | Can return if feeling able |
| Day 3-4 | Significant improvement in pain | Most people return to work |
| Day 5-7 | Symptoms mostly resolved | Normal capacity |
| Day 10 | Complete antibiotic course | Fully recovered |
Critical rule: You are contagious until you've been on antibiotics for at least 24 hours. Do not return to work before this point, regardless of how you feel.
When to Stay Home vs Return
Must stay home:
- First 24 hours after starting antibiotics (contagious)
- If you have a fever
- If you cannot swallow (dehydration risk)
- If you work with children, elderly, or immunocompromised people
Can return after:
- 24+ hours on antibiotics AND no fever AND able to perform duties
- Typically day 2-3 for most workers
Without Antibiotics (Not Recommended)
If strep is left untreated:
- Contagious for 2-3 weeks
- Symptoms last 7-10 days
- Risk of complications (rheumatic fever, kidney problems)
- Should NOT return to work until symptoms fully resolve
Get treated. Untreated strep is a public health risk and can lead to serious complications.
Sick Note Considerations
- 1-2 day absence (with antibiotics): May not require a note depending on employer
- 3+ days: Most employers request documentation
- If you needed to see a doctor for the prescription: That visit documentation may suffice
- If diagnosed via rapid test at pharmacy: Some employers accept pharmacy documentation
Frequently Asked Questions
Can I go to work with strep throat if I feel okay?
Not in the first 24 hours of antibiotics — you're still contagious. After 24 hours, if you feel well enough to work, you can return.
How long is strep throat contagious?
With antibiotics: 24 hours after first dose. Without antibiotics: up to 2-3 weeks.
Do I need a sick note for strep throat?
If you're only off 1-2 days and your province protects short absences, you may not need one. For longer absences, documentation is advisable.
