Persistent tonsillitis may become another symptom of covid-19 and immunonutrition supports healing process in patient with history of tonsillitis: a case report

A health survey supervisor aged 26 years old with normal body temperature conducted a PCR swab test as research protocol at the end of data collection. He already felt unwell three days before the PCR swab test. The test showed positive for COVID-19. He self-isolated and consumed nutritional supplements, including B vitamins, vitamin C, vitamin D, zinc, propolis, and probiotics. Persistent tonsillitis with odynophagia was found as the primary symptom. Other symptoms like sore throat, hot sensation in feet and hands, headache and mucus production behind the nose appeared only for one or two days. Fever, dry cough, and diarrhea were not found. On day 8 of confirmation, the PCR swab test showed a negative result. Even several days after the negative result, an enlarged tonsil was still observed, but without odynophagia. We propose persistent tonsillitis should be regarded as a new symptom of COVID-19, and immuno-nutrition supports the healing process in a patient with a tonsillitis history.
