ID4U Episode 29 Marburg Virus Disease

ID4U Episode 29 Marburg Virus Disease

Dr. Jessica Pelletier, Dr. Sidwell Kyeyune, and Dr. Kakande Reagan discuss the epidemiology, pathophysiology, clinical presentation, diagnostic workup, management, and prevention of Marburg virus disease. Take-Home Points: * Marburg virus disease infection can occur via zoonotic exposure to Egyptian fruit bats or via human-to-human transmission. * Initial symptoms are non-specific but can progress to hemorrhage, multiorgan failure, and death. * Diagnosis involves RT-PCR. * Treatment is mostly supportive, including blood products (for bleeding), IV fluid resuscitation, and symptom control (with avoidance of NSAIDs). * Remdesivir and monoclonal antibodies may be given under compassionate use. * PPE involves standard, contact, and droplet precautions, with environmental decontamination via chlorine. * Morbidity and mortality are high, so infection prevention is essential.

ID4U Episode 28 Crimean-Congo Hemorrhagic Fever

Dr. Jessica Pelletier, Dr. Lawrence Mendy, Dr. Elicana Nduhuura, and Malan Alfred Opoka discuss the epidemiology, pathophysiology, clinical presentation, diagnostic workup, management, and prevention of Crimean-Congo Hemorrhagic Fever (CCHF). Take-Home Points: * CCHF is a severe tick-borne viral illness caused by CCHFV, occurring in Africa, the Middle East, Asia, and parts of Europe. * Transmission is primarily via Hyalomma tick bites, but also through contact with infected animal tissues or the blood/body fluids of infected patients. * High-risk groups include farmers, livestock handlers, abattoir workers, veterinarians, hunters, military personnel, healthcare workers, and travelers to endemic areas. * CCHF progresses through four phases: incubation, prehemorrhagic, hemorrhagic, and convalescent. Early symptoms are nonspecific (fever, headache, myalgia, back pain, nausea, vomiting, abdominal pain, weakness). Hemorrhagic signs (e.g., petechiae, epistaxis, hematemesis) indicate severe disease. * Labs often show thrombocytopenia, leukopenia, elevated liver enzymes, and DIC. * Diagnosis is by RT-PCR in the acute phase; serology (IgM/IgG) is useful later. * Management is supportive: isolation, fluids, blood products, and avoidance of NSAIDs. Ribavirin is commonly used, though mortality benefit is uncertain. * Mortality ranges from 10–40%, depending on severity and complications (e.g., shock, DIC, multiorgan failure). * Prevention includes tick avoidance, protective equipment, animal handling precautions, and infection control in healthcare settings.

ID4U Episode 27 Lassa Fever

Dr. Jessica Pelletier and Dr. Sabel Bass co-interview Dr. Valentine Aroh, discussing the epidemiology, pathophysiology, clinical presentation, diagnostic workup, management, and prevention of Lassa fever. Take-Home Points: * Lassa fever is a viral hemorrhagic fever endemic to West Africa. * Rats are the primary animal reservoir and are becoming more of an issue as dry seasons lengthen in the face of climate change. * Mortality rates vary widely due to underreporting; many cases are asymptomatic, but among the symptomatic, mortality is quite high. * Pregnant women are at extremely high risk for severe disease and death. * Lassa can resemble other endemic viral illnesses and hemorrhagic fevers, but facial swelling is a distinctive feature. * RT-PCR is the gold standard for diagnosis. * Treatment is largely symptomatic, but Ribavirin can be tried in the first 6 days of symptoms. * Contact and droplet precautions are essential to prevent the spread of disease.

ID4U Episode 26 Vaccine Hesitancy Part 1

Dr. Jessica Pelletier and Dr. Nicholas Maxwell discuss two re-emerging diseases in the era of the rising phenomenon of vaccine hesitancy: measles and mumps. They cover vaccine safety for preventing both diseases, followed by the clinical presentation, diagnosis, management, and close-contact protection measures for measles and mumps. The episode closes with a discussion of how to talk to families about vaccines. Take-Home Points: * We are seeing a resurgence of vaccine-preventable diseases; this is multifactorial, but some of it has to do with the pandemic, global conflict, and misinformation. * Though there are several formulations and the dosing schedule for measles plus or minus mumps vaccine may vary from country to country, these vaccines are highly safe and effective in the prevention of these diseases. * It is our responsibility as healthcare providers to educate our patients and their families about vaccine safety, finding ways to connect with them without judgment.

ID4U Episode 25 Rabies

Dr. Jessica Pelletier, Dr. John George Johnson, Dr. Akan Otu, and Dr. Bri Bennett discuss the epidemiology, pathophysiology, clinical presentation, diagnostic workup, management, and prevention of rabies. Take-Home Points: * Rabies is an encephalomyelitis that occurs after inoculation from infected saliva. * Many countries have successfully eradicated this disease, but 59,000 people still die of the disease yearly. * Canine vaccination programs, PREP for high-risk individuals, and PEP after potential rabies exposure prevent disease. * Initial symptoms are flu-like and non-specific. Once symptoms have started, all we can offer is supportive care.
