About

Bio

Dr.Melgarejo has had a fascination for infectious diseases since early in his career. During his school years, he used to read about "viral exanthems" that were common in his native country of Colombia (such as measles, rubella, etc.). During medical school, Dr. Melgarejo volunteered in a virology research lab at the National Institutes of Health in Colombia, where he worked on epidemiologic surveillance of polyomyelitis. He then moved to the United States to pursue his Graduate Medical Education, first a residency in Internal Medicine and then a fellowship in Infectious Diseases. He trained in Houston, a large urban area with a very diverse population that provided him the chance to train in the diagnosis and treatment of a wide array of infectious diseases. His research work has been focused on infectious diarrhea, particularly in <i>Clostridium difficile </i>and <i>Escherichia coli </i>(enteroaggregative).

Dr ASAP: The fact that you have not urinated in 12 hours, along with vomiting and diarrhea, means that you are probably dehydrated and will need fluid replacement right away. Since you are not keeping anything down, you will need IV fluids asap. What are you waiting for ! you should be at your doctor's office or in the emergency room !

Yes: Any medication taken in quantities larger than indicated can result in unwanted side effects, which can be harmful or lethal. Antibiotics are not the exception.

Tricky question: There are multiple HIV tests out there, and the right answer depends on what it is used for, and what are the expected results.In general, the HIV elisa (antibody test) has very good sensitivity and is the screening method of choice. However, in certain circumstances it can be falsely positive, therefore the HIV western blot is very useful to confirm infection.There are multiple other tests though.
