Incubation Period For Strep Throat: Contagious Period And Complications

The time period between the invasion of the tissue by bacteria or virus, and the appearance of clinical signs and symptoms of infection is called the incubation period of the disease.

Incubation Period For Strep Throat

Incubation period of streptococcus sore throat is about 2 to 4 days. The disease is contagious, and is transmitted by airborne infection like sneezing, mucus from throat, coughing and eating food preparations contaminated with streptococcus bacteria such as eating ice-cream, using common utensils and deep kissing.

Strep Throat Contagious Period

If a person is suffering from strep throat he will remain contagious for 24 to 48 hours after starting antibiotics.

The symptoms of strep throat may prolong for some more time and recede after 5 to 6 days of antibiotic therapy.

A person can remain infective without treatment for 3 weeks, even if he does not manifest any symptoms of sore throat.

Complications Of Strep Throat

Complications of strep throat are less common as a result of mild form of disease and the introduction of effective chemotherapy. But when present they are

  • Rheumatic fever (a rare sequel but a serious one).
  • Acute kidney inflammation (nephritis).
  • Ear infection.
  • Sinusitis.

Therefore it is very important to treat strep throat and avoid its complications.

    My strep is recurring (4 times in the past year). Although I have almost completed the antibiotic treatment for my most recent Strep infection (Clindamycin 300mg / 4x/day), I now seem to have symptoms of sinusitis and ear infection (clogged ear, sinus pain). Is it possible the antibiotics have failed?
