Immunological Memory01:23

Immunological Memory

14.3K
Immunological memory, a pivotal pillar of the adaptive immune system, is responsible for the body's ability to remember and respond more swiftly and effectively to previously encountered pathogens. This remarkable feature is what makes vaccines so effective in preventing diseases.
What is Immunological Memory?
Immunological memory is an integral function of the immune system that allows it to recognize and react more rapidly and effectively to pathogens previously encountered. This feature...

Viral Recombination00:57

Viral Recombination

24.4K
Cells are sometimes infected by more than one virus at once. When two viruses disassemble to expose their genomes for replication in the same cell, similar regions of their genomes can pair together and exchange sequences in a process called recombination. Alternatively, viruses with segmented genomes can swap segments in a process called reassortment.

Retrovirus Life Cycles01:10

Retrovirus Life Cycles

48.3K
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...

Infection01:20

Infection

9.9K
When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of infection.
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...

Stages of Infection01:26

Stages of Infection

62.4K
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...

Summary

Reinfection with coronavirus disease 2019 (COVID-19) is possible. Two patients experienced symptom resolution and negative tests, only to relapse weeks later with milder symptoms, suggesting viral dormancy.

Area of Science:

  • Infectious Diseases
  • Virology
  • Immunology

Background:

  • The potential for reinfection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus causing coronavirus disease 2019 (COVID-19), remains an area of active investigation.
  • Previous hypotheses regarding recurrent positive tests have often been attributed to disease relapse or asymptomatic/mild initial infections.

Observation:

  • This report details two confirmed cases of COVID-19 patients who initially recovered, testing negative for SARS-CoV-2.
  • Weeks post-recovery, both individuals presented with a recurrence of milder COVID-19 symptoms.
  • Subsequent testing confirmed a new positive SARS-CoV-2 culture swab in both patients.

Findings:

  • These cases suggest that coronavirus disease 2019 may not always result in complete viral clearance after initial recovery.
  • The findings indicate a potential for SARS-CoV-2 to remain dormant within the host's body.
  • A prolonged incubation or latent phase, followed by a later symptomatic relapse, is a possibility in some COVID-19 cases.

Implications:

  • This phenomenon of potential viral dormancy and relapse has significant implications for understanding COVID-19 transmission dynamics and patient management.
  • Further research is warranted to elucidate the mechanisms behind this apparent dormancy and relapse.
  • Clinical guidelines may need to consider the possibility of late-stage relapse in patients previously diagnosed with COVID-19.
