Is strep throat contagious, and how long are you infectious in Europe?

Strep throat explained: Group A Streptococcus transmission, incubation period, contagious timeline, and treatment criteria.

In this episode, we clarify how strep throat spreads, how long someone remains contagious, and when medical treatment is required under EU clinical guidance.

You’ll learn:

• How Group A Streptococcus is transmitted (respiratory droplets, close contact)

• The typical incubation period (2–5 days)

• How long someone is contagious without antibiotics

• When infectiousness reduces after starting antibiotic treatment

• Symptoms that suggest bacterial rather than viral sore throat

• When throat swab testing is recommended

• Situations where an antibiotic request may be declined without clinical criteria

We explain how doctors assess fever, tonsillar swelling, lymph node tenderness, absence of cough, and exposure history using established diagnostic frameworks during an online consultation in the EU. Not all sore throats are caused by streptococcal infection, and antibiotics are prescribed only when medically indicated.

This episode reflects the clinical standards used by Mobi Doctor, where infection-related consultations are reviewed by a registered physician in line with EU prescribing guidance.
