Norovirus infection in immunocompromised hosts.
1Caliciviruses Section, Laboratory of Infectious Diseases, National Institute of Allergy and Infectious Diseases, National Institutes of Health, Bethesda, MD, USA.
Summary
Norovirus infections typically resolve quickly. However, in immunocompromised individuals, norovirus can cause chronic infections lasting years, presenting a challenge for treatment and potentially serving as a reservoir.
Area of Science:
- Virology
- Immunology
- Gastroenterology
Background:
- Norovirus infections are usually acute and self-limiting, lasting 2-3 days.
- Chronic norovirus infections in immunocompromised individuals can persist for weeks to years.
- The mechanisms of persistent norovirus infection and the role of immunocompromised hosts as reservoirs are unknown.
Purpose of the Study:
- To investigate the mechanisms of persistent norovirus infection.
- To understand the role of immunocompromised individuals as reservoirs for norovirus.
- To explore potential new treatment approaches for chronic norovirus infections.
Main Methods:
- Study of a patient cohort with chronic norovirus infection.
- Analysis of norovirus persistence mechanisms.
- Investigation of the host immune response in immunocompromised individuals.
Main Results:
- Chronic norovirus infections in immunocompromised individuals can last for extended periods.
- Persistent infections pose significant clinical management challenges.
- Further research may elucidate norovirus biology and treatment strategies.
Conclusions:
- Chronic norovirus infection in immunocompromised individuals is a significant clinical issue.
- Understanding persistent norovirus infections may reveal new therapeutic targets.
- Immunocompromised hosts may act as reservoirs, impacting public health.

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...

01:26Factors Affecting the Risk of Infection
14.1K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

01:25Immunodeficiency Diseases
3.5K
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.

01:26Stages of Infection
69.9K
Stages of infection describe what happens to a susceptible host once a pathogen invades the human body. The stages of infection are incubation, prodromal, illness, stage of decline, and convalescence. The incubation stage is the period from exposure to a pathogen until symptoms start. The infected person is unaware of impending illness as the pathogens grow and multiply within the body. The duration may vary depending on the type of infection. The incubation period of measles averages ten to...

01:25Arboviral Encephalitis
52
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...

01:28Infectious Diseases and Their Occurrence
83
Infectious diseases appear in populations through various transmission patterns, influenced by pathogen characteristics, population immunity, environmental conditions, and social behavior. Understanding these patterns is essential for effective public health surveillance and intervention. These categories—sporadic, outbreak, epidemic, pandemic, and endemic—help frame the nature and scope of disease events.Sporadic diseases occur irregularly and infrequently, without a predictable...
