Sore throat, fever, difficulty swallowing: the first signs of tonsillitis are almost all similar. The common reflex is to open the mouth in front of a mirror to check the color of the tonsils. Red and swollen, it’s called red tonsillitis. Covered with a whitish deposit, it’s called white tonsillitis. However, this visual distinction says nothing about the origin of the infection, and it is the origin that determines the treatment.
Why the color of the tonsils is not enough for diagnosis
The appearance of the throat provides guidance, but it does not make a definitive diagnosis. Red tonsillitis can be caused by a virus or by bacteria. White tonsillitis can also be viral or bacterial. The color does not allow us to distinguish between viral and bacterial tonsillitis.
The real medical issue lies elsewhere: identifying whether a group A streptococcus is involved. It is this bacterium that justifies antibiotic treatment and, without management, can lead to complications (acute rheumatic fever, kidney damage). An article detailing how to distinguish between white and red tonsillitis emphasizes this fundamental point.
A viral tonsillitis, on the other hand, heals spontaneously within a few days. Prescribing an antibiotic in this case does not speed up recovery and contributes to antibiotic resistance. Therefore, the entire approach relies on a precise differentiation between the two origins.
Symptoms of viral or bacterial tonsillitis: concrete clues
Rather than relying on color, certain associated signs guide the doctor towards one possibility or the other.
Clues favoring a viral origin
Viral tonsillitis often occurs within a broader picture of respiratory tract infection. Have you noticed that the sore throat is accompanied by a runny nose or a cough? That’s a strong signal.
- Presence of cough, nasal discharge, or hoarseness, signs that are rare in streptococcal tonsillitis
- Associated conjunctivitis (red, watery eyes), common with certain adenoviruses
- Gradual onset of symptoms over two or three days, with moderate fever
- Muscle pain or diffuse aches, typical of a general viral state
The majority of tonsillitis cases in adults are viral. In children, the proportion of bacterial tonsillitis is higher, making screening tests particularly useful in this age group.
Clues favoring streptococcal tonsillitis
High fever with sudden onset, intense pain when swallowing, and swollen lymph nodes under the jaw form the classic trio. The pain may radiate to the ear (referred otalgia), even without actual otitis.
The absence of cough and cold symptoms strengthens the suspicion of a bacterial infection. In children, abdominal pain or nausea may sometimes accompany the picture, which can mislead the diagnosis if one does not think to examine the throat.
Rapid streptococcal test: when to request it during a consultation
The rapid diagnostic orientation test (TROD) is performed in a medical office or pharmacy in certain cases. A swab from the back of the throat provides results in a few minutes. A positive TROD confirms the presence of streptococcus and justifies antibiotic treatment. A negative result helps avoid unnecessary prescriptions.
Why not systematically treat with antibiotics as a precaution? Because the vast majority of tonsillitis cases are viral, and blind antibiotic treatment exposes patients to side effects without benefit. The test is inexpensive, takes five minutes, and decisively alters management.
A often overlooked point: the appearance of the throat may seem trivial while streptococcus is indeed present. Moderately red tonsils, without visible white deposits, do not rule out a bacterial infection. The test remains relevant whenever there is a clear fever and absence of cough, even if the throat does not show a dramatic picture.
Warning signs in children: when to consult without delay
In a young child, tonsillitis can manifest deceptively. The sore throat is not always verbalized, and the child expresses their pain differently.
- Refusal to eat or drink, especially solid foods, signaling intense pain when swallowing
- Unusual drooling in a child who typically does not drool
- Difficulty breathing or noisy breathing, which may indicate significant swelling of the tonsils
- Unexplained agitation or, conversely, marked prostration with high fever
A child who drools, refuses to drink, or has difficulty breathing should be seen quickly by a doctor. These signs go beyond the scope of a simple tonsillitis and may indicate a phlegmon (peritonsillar abscess) or partial airway obstruction.
In infants, high fever alone is enough to warrant medical advice, even without visible signs in the throat. The immature immune system makes complications more likely and clinical diagnosis more difficult.
Relieving pain while waiting for diagnosis
Even before the consultation, a few simple measures help limit discomfort. Paracetamol remains the first-line analgesic for fever and throat pain, at doses appropriate for weight. Cool or warm drinks (depending on preference) facilitate swallowing. Soft foods are easier to swallow than bread or dry cereals.
Anti-inflammatories should not be taken without medical advice in cases of suspected bacterial tonsillitis, as they may promote the occurrence of local complications such as phlegmon.
Keep in mind a simple guideline: if the sore throat persists beyond three days, if the fever does not respond to paracetamol, or if new symptoms appear (rash, painful joints), a consultation is necessary, whether or not a first opinion has already been obtained. The color of the tonsils may have changed in the meantime, but it is the overall clinical picture, and not just the visual aspect, that guides the medical decision.
