COVID-19 pneumonia has invaded the world and continues to expand. The current evidence of the immune system reaction to this viral pneumonia shows that the post-infectious immunity against the virus may be temporary, and the virus may reinfect the patients after healing from the previous one. Here is presented a 55-year-old female patient, as a known case of Hodgkin lymphoma, diagnosed with COVID-19 reinfection during 40 days. Such evidence may be helpful in further understanding the immunology of the disease.
