Opportunistic infections in immunocompromised HIV patients have for years been the main cause of mortality in this population, such as pneumonia caused by the fungus Pneumocystis jiroveci. SARS-CoV-2 infection is the cause of the COVID-19 pandemic. During this period, many patients who had a clinical similar to COVID-19 sought medical attention and that particular diagnosis was attributed to all of them. Given this situation, in many cases it was suspected that the patients had an infection by SARS-CoV-2, resulting in incorrect in-hospital treatment and measures. We present the case of an HIV-infected male who presented with pneumonia associated with probable COVID-19 or P. jirovecii infection. The aim of this case report is to establish the differences between SARS-CoV-2 and P. jirovecii pneumonia.

COVID-19 is a disease caused by SARS-CoV-2, a virus that represents a serious threat to global health. The objective of the article is to deepen into the structure of the structural and non-structural proteins of SARS-CoV-2 and their role during the infection of its target cells; also to propose molecules from in silico studies that inhibit proteins of the viral cycle for potential pharmacological treatments. The SARS-CoV-2 genome has ORFs that encode sixteen non-structural proteins (Nsp1-16), four structural proteins (Spike, Envelope, Membrane, and Nucleocapsid), and nine accessory proteins; that fulfill various functions in the entry of the virus and its viral cycle. In silico studies of drugs such as disulfiram and viomycin, and molecules found in plants as Azadirachta indica, the tea plant, and Andrographis paniculata have shown inhibitory effects on the SARS-CoV-2 viral cycle.
