Summary
This study reports a case of prolonged COVID-19 viral shedding lasting 110 days in a patient with lymphoma. This finding contributes to understanding the contagious period and potential chronicity of COVID-19.
Area of Science:
- Infectious Diseases
- Hematology
- Virology
Background:
- COVID-19 pandemic has caused significant mortality.
- Typical viral shedding lasts 7-10 days.
- Uncertainty exists regarding prolonged shedding and COVID-19 chronicity.
Purpose of the Study:
- To present a case of extended viral shedding in a COVID-19 patient with hematological malignancy.
- To document the longest reported polymerase chain reaction (PCR) positivity duration.
Main Methods:
- Case report of a patient with lymphoma.
- Monitoring of viral shedding via PCR.
Main Results:
- The patient exhibited PCR positivity for 110 days.
- This represents the longest duration of PCR positivity documented in the literature for COVID-19.
Conclusions:
- Prolonged viral shedding can occur in immunocompromised patients, such as those with lymphoma.
- Further research is needed to correlate prolonged PCR positivity with sustained contagiousness and potential COVID-19 chronicity.

01:26Stages of Infection
59.6K
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...

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...

5.9K
Chronic pharyngitis refers to persistent inflammation of the pharyngial mucosa.
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...

Understanding the variety of primary symptoms and systemic complications that characterize chronic obstructive pulmonary disease (COPD) is crucial for healthcare professionals.
Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.

01:20COPD: Pathogenesis and Clinical Features
667
Chronic obstructive pulmonary disease (COPD) is a group of lung conditions that progressively worsen over time, including chronic bronchitis and emphysema. This cluster of diseases collectively leads to a gradual and irreversible decline in lung function over time.
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...
