COVID-19, also called severe acute respiratory distress syndrome coronavirus 2 (SARS-CoV-2), originated in Wuhan, China. It has caused significant morbidity and mortality worldwide and has been declared a global pandemic by the WHO. Influenza occurs mainly during the winter, with the burden of disease determined by several factors, including the effectiveness of the vaccine that season, the characteristics of the circulating viruses, and how long the season lasts. We describe the case of a 66-year-old woman who was diagnosed with influenza A and COVID-19 co-infection. LEARNING POINTS• COVID-19 can co-occur with other viral infections. • Some of these co-infections have active treatments, while supportive treatment is the mainstay of treatment for others.

Human immunodeficiency virus (HIV) infection is a known hypercoagulable state with venous thromboembolism with a high mortality rate compared to the general population. The homeostatic balance in HIV infected patients improves with treatment compared to those who are not.  A decreased hypercoagulable state noted by low levels of Von Willebrand factor, factor VIII and d-dimer levels along with higher protein C and S activity in patients on treatment suggests that hypercoagulable state is partially correctable with highly active antiretroviral therapy.  HIV with heart muscle involvement can present as myocarditis or as dilated cardiomyopathy with left or right ventricular dysfunction.  Here we present a case of a 57-year-old man with a known history of HIV infection, noncompliant with medical therapy presenting with dilated cardiomyopathy with biventricular thrombi with reduced protein C, protein S, and Antithrombin III levels.
