Introduction: Since the COVID 19 had been declared as a global pandemic, young people were not spared from COVID 19 infection. Pneumonia in young adults ranged from mild to severe, and in many cases resulted in death.

Methods and subjects: A descriptive and analytical study carried out in patients diagnosed with SARS-COV2 positive either by PCR or chest scanner or rapid test during the period from November 2020 to July 2021 hospitalized in the Covid 19 Unit. We defined young subjects by an age strictly below 65 years, according to the WHO.

Results : We included 103 young patients whose average age was 51 years [22-64 years],60.2% were male. The comorbidities were : diabetes (25.2%), arterial hypertension (18.4%) and asthma (12.6%). Twelve percent of patients were active smokers. The most common symptoms were dyspnea (75.5%), fever (72.8%), dry cough (78%) and chest pain (35%). The clinical examination found polypnea in 79.6% of cases with an average respiratory rate of 25 cycles per minute [12-40] and an SaO2 of 86.5% [56%-100%], signs struggle in 42.7% of cases and tachycardia in 31.3% of patients. Pulmonary auscultation found crackles in 63.1% of cases. In biology, a CRP greater than 100 mg/l was noted in 31.6% of patients. Chest CT showed minimal involvement (0%-10%) in 21.4% of patients, moderate involvement (11%-25%) in 18.4%, significant involvement (26%-50%) in 27 2% of cases, severe impairment (51%-75%) in 18.4% of patients and critical impairment (greater than 75%) in 14.6% of cases. Among our population, 21.4% were hospitalized in intensive care and 5.8% were intubated. The death rate was 25.2%.

Conclusion : Young adults can develop severe forms of covid 19 pneumonia with a poor prognosis in many cases.
