Pharyngitis is inflammation of the pharynx, the mucous membrane and underlying structures of the back of the throat. This area serves as a shared pathway for both the respiratory and digestive tracts. Air passes through the nasopharynx and oropharynx down toward the larynx and trachea, while food travels from the oral cavity into the esophagus.
When infectious agents or irritants invade this region, the local tissues react with swelling, redness, and pain. Understanding this basic anatomy helps midwives explain to patients why a simple throat infection can cause associated symptoms like difficulty swallowing, ear pain due to eustachian tube proximity, and tender neck lymph nodes.
Most cases of pharyngitis are caused by viruses, including rhinoviruses, adenoviruses, and influenza. These viral infections typically resolve on their own with supportive care and do not require antibiotics.
Bacterial pharyngitis, most notably caused by Group A beta-hemolytic Streptococcus (often called GABHS or strep throat), requires specific antimicrobial treatment to prevent serious downstream health issues. Midwives must remain alert to clinical clues, because viral and bacterial sore throats look remarkably similar on visual inspection. Misprescribing antibiotics for a viral sore throat contributes to global antimicrobial resistance without speeding up patient recovery.
Differentiating between viral and bacterial pharyngitis purely by looking inside the mouth is notoriously difficult, but certain symptom patterns offer strong clues.
Midwives should carefully inspect the oral cavity using adequate lighting and a tongue depressor while wearing clean gloves, noting the presence of exudates, petechiae on the soft palate, and overall mucosal erythema.
When clinical signs suggest a bacterial infection, confirmation is sought through diagnostic testing. The two main tools are the Rapid Antigen Detection Test (RADT) and the traditional throat culture.
Performing a correct throat swab requires proper technique to ensure an adequate sample:
A negative rapid test in children or pregnant women with high suspicion is often followed up with a backup throat culture because culture remains the gold standard for sensitivity.
If a throat swab confirms Group A Streptococcus, first-line treatment is typically penicillin or amoxicillin, given for a full ten-day course unless the patient has a documented allergy.
Completing the entire course of antibiotics is vital, even after the throat pain disappears within a couple of days. Stopping medication early allows surviving bacteria to multiply, leading to a relapse or severe secondary complications.
For pain and fever relief, analgesics like paracetamol or ibuprofen are administered. Midwives play a key role in educating patients that antibiotics do nothing to cure viral sore throats, thereby reinforcing responsible medication use across the community.
Because swallowing is painful, patients with pharyngitis often neglect fluid intake, placing them at risk for dehydration. Encouraging adequate oral fluid intake is a primary nursing priority. Cool or warm liquids, soothing teas with honey (for patients over one year of age), and broths help keep the mucous membranes moist.
Gargling with warm saltwater helps reduce local edema and eases discomfort. Soft foods, custards, and porridges are easier to swallow than rough or spicy foods. Rest is equally important to help the immune system fight off the infection, whether viral or bacterial.
While most cases of pharyngitis resolve without incident, untreated or poorly managed streptococcal infections can lead to serious local and systemic complications.
Midwives must recognize red flag symptoms—such as drooling, severe neck swelling, inability to swallow liquids, or respiratory distress—and refer patients for immediate medical evaluation.
