Insights

Concurrent dengue virus (DEN) and human immunodeficiency virus 1 (HIV) infections were observed in Havana during a DEN-3 epidemic. HIV-infected patients with dengue fever showed no accelerated HIV progression or decreased CD4+ cell counts.

Area of Science:

  • * Virology and Infectious Diseases
  • * Epidemiology of Viral Infections

Background:

  • * Dengue virus (DEN) and human immunodeficiency virus 1 (HIV) are prevalent in overlapping geographical regions.
  • * Limited data exists on the clinical outcomes of co-infection with DEN and HIV.

Observation:

  • * Two cases of concurrent DEN and HIV infection were identified during the 2001-2002 DEN-3 epidemic in Havana.
  • * Both patients presented with symptoms of dengue fever.

Findings:

  • * Serological confirmation of DEN infection in HIV-positive individuals.
  • * Patients maintained normal CD4+ cell counts and showed no accelerated progression of HIV disease despite symptomatic dengue fever.
  • * This represents a previously unreported occurrence of DEN-3 infection in HIV-positive individuals.

Implications:

  • * Highlights the potential for underdiagnosis of DEN/HIV co-infections in endemic areas.
  • * Suggests that symptomatic dengue may not significantly impact HIV disease progression in co-infected individuals.
  • * Underscores the need for further research into the clinical management and epidemiological surveillance of this mixed viral infection.

Cytomegalovirus Disease01:27

Cytomegalovirus 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...
Yellow Fever01:18

Yellow 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...
Immunodeficiency Diseases01:25

Immunodeficiency Diseases

Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.
There are three main causes of immunodeficiency disorders...
Sexually Transmitted Infections01:26

Sexually Transmitted Infections

Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...
Retrovirus Life Cycles01:10

Retrovirus Life Cycles

Retroviruses have a single-stranded RNA genome that undergoes a special form of replication. Once the retrovirus has entered the host cell, an enzyme called reverse transcriptase synthesizes double-stranded DNA from the retroviral RNA genome. This DNA copy of the genome is then integrated into the host’s genome inside the nucleus via an enzyme called integrase. Consequently, the retroviral genome is transcribed into RNA whenever the host’s genome is transcribed, allowing the retrovirus to...
Arboviral Encephalitis01:25

Arboviral 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...
