Summary
Viral hemorrhagic fevers like Lassa and yellow fever cause many deaths globally. Travelers should be aware of prevention for dengue and yellow fever, as other hemorrhagic fevers are rare.
Area of Science:
- Tropical medicine
- Infectious diseases
- Public health
Context:
- Viral hemorrhagic fevers (VHFs) pose significant global health risks, causing substantial mortality annually.
- Transmission routes include arthropod vectors (mosquitoes, ticks) and rodent excreta.
- Travelers to endemic regions are at risk of contracting specific VHFs.
Purpose:
- To inform about the risks of viral hemorrhagic fevers for travelers.
- To outline prevention and treatment strategies for common travel-related VHFs.
- To guide diagnostic priorities in febrile patients with hemorrhagic diathesis returning from the tropics.
Summary:
- Yellow fever is preventable with a vaccine, while dengue prevention involves avoiding mosquito bites and symptomatic treatment.
- Lassa fever and Ebola fever are rare in travelers, with specific management protocols available.
- In tropical febrile patients with hemorrhagic diathesis, diagnostic focus should prioritize common treatable conditions like malaria, typhoid fever, rickettsiosis, or bacterial sepsis over rare VHFs.
Impact:
- Enhances traveler awareness and preparedness for infectious disease risks.
- Supports clinicians in differential diagnosis for febrile hemorrhagic illnesses in returning travelers.
- Contributes to public health strategies for managing and preventing viral hemorrhagic fevers.

01:18Viral Meningitis
Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...
01:28Rabies
Rabies is a lethal zoonotic disease caused by a single-stranded, negative-sense RNA virus of the Lyssavirus genus, within the family Rhabdoviridae. Its primary mode of transmission to humans is through bites or saliva-contaminated scratches from infected mammals such as dogs, bats, raccoons, or foxes. Transmission can also occur if infectious saliva contacts abraded skin or intact mucous membranes, including the conjunctiva.Viral Entry and Early ReplicationOnce introduced at the bite or scratch...
01:25Arboviral Encephalitis
Arboviral encephalitis refers to brain inflammation caused by arthropod-borne viruses, particularly those transmitted through mosquito vectors. Among these, West Nile virus (WNV), a member of the Flaviviridae family, is a significant public health concern. WNV is an enveloped, positive-sense, single-stranded RNA virus. Human infection typically begins when an infected mosquito introduces the virus into the dermis during feeding. The primary transmission cycle involves birds as amplifying hosts...
01:18Yellow Fever
Yellow fever is a viral hemorrhagic disease caused by the yellow fever virus (YFV), a member of the Flaviviridae family. It is transmitted primarily by Aedes and Haemagogus mosquitoes in tropical and subtropical regions of Africa and South America. After transmission through a mosquito bite, the virus initially replicates in skin-resident immune cells such as dendritic cells and macrophages. These cells then migrate to the lymph nodes, where viral replication increases, eventually leading to...
01:27Cytomegalovirus Disease
Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...
01:28Viral Hepatitis I: Introduction
Viral hepatitis is an inflammatory condition of the liver caused by infection with hepatotropic viruses, most commonly hepatitis A, B, C, D, and E. Despite variations in structure and transmission, all viruses mentioned infect hepatocytes and provoke immune responses that can hinder liver function. Additionally, some non-hepatotropic viruses can also lead to hepatic inflammation.Hepatitis A VirusHepatitis A virus (HAV) is transmitted through the fecal–oral route, typically by ingestion of food...
