As an expert in infectious diseases, editor of the Journal of Infectious Diseases and author of the textbook Infectious Diseases: A clinical short course, McGraw-Hill April 2020, I have been concerned about the misinformation being shared about the COVID-19 epidemic. How did this disease develop? Where did it come from? How does it cause diseases? The answers to these questions will be answered in the first video of module 1. The world has been startled and frightened by the rapid spread of this virus throughout the world. In Video 2 the epidemiology as presently understood is reviewed. This video will be periodically updated recognizing the rapid progression of the pandemic. Many want to know how does this disease present, what are the symptoms associated with COVID-19? How dangerous is COVID-19? Who is at risk of dying? All these questions are answered in Video 3. And finally how is this disease best treated and how can we slow the spread of the infection? These questions are answered in video 4. In addition to the videos multiple choice questions are included to test your understanding and there is an epidemiology peer reviewed exercise designed to teach you how this infection is spread and to show the power of the tracing of cases and isolating those who are infected. The second peer review exercise will encourage you to create a campaign to shift your countries culture to embrace behaviors that can lead to suppression of the epidemic, behaviors that will save lives. After completing this course you will be armed with the knowledge and skills to make a difference and help to bend the curve.
Clinical Characteristics of COVID-19: Course and Prognosis

A very informative course regarding the ongoing pandemic! Although it just needed some update due to recent data and studies. The instructor is great!
This course gave a good overview of COVID-19 from a clinician point of view. This complements another COVID-19 course I took with COursera
COVID-19 presents similarly to influenza. The most common symptoms are fever (>100.4 °F or 38°C), dry cough, and shortness of breath. Other common symptoms include marked fatigue, myalgias (muscle aches), headache, and sorethroat. Chest tightness can develop early in severe cases. Diarrhea and vomiting less commonly can be presenting complaints. Physical exam is usually unremarkable with the exception of fever, tachycardias (elevated pulse), an elevated respiratory rate and low oxygen saturation on room air. Lymphadenopathy is usually not present and pulmonary exam is unremarkable. Laboratory studies are nonspecific with a low lymphocyte count, low platelets, elevated CRP, and normal procalcitonin level. CXR is insensitive (60% sensitivity) chest CT being more sensitive and highly specific and is the study of choice in patients being considered for admission to the hospital. Treatment consists of supportive care by administering nasal O2 to maintain saturation above 92%. If nasal O2 fails to achieve appropriate oxygenation intubation and mechanical ventilation with PEEP (positive end expiratory pressure) is recommended and standard ARDS protocols should guide care. Septic shock with end organ damage can develop and standard sepsis protocols are recommended with the exception of fluid administration which should be cautious.
