Summary
Human papillomavirus type 73 (HPV73) single infections are rare but can lead to cervical cancer. High viral load is linked to persistent HPV73 infection and increased pathogenicity.
Area of Science:
- Gynecology
- Virology
- Oncology
Background:
- Human papillomavirus (HPV) infection is a primary cause of cervical cancer.
- Different HPV types possess varying degrees of pathogenicity.
- Limited clinical data exists for HPV73 single infections.
Purpose of the Study:
- To analyze the clinical characteristics of HPV73 single infections.
- To determine the infection rate of HPV73.
- To investigate the association between viral load, persistent infection, and pathogenicity of HPV73.
Main Methods:
- Collection of cervical exfoliated cells for HPV73 testing.
- Analysis of infection rates and clinical characteristics in HPV73 single infection cases.
- Correlation analysis of viral load with cytology results, persistent infection, and clearance.
Main Results:
- HPV73 positive rate was 0.14% among tested women.
- In 214 HPV73 single infection cases, 182 had normal cytology, 24 CIN1, 5 CIN2, 1 CIN3, and 1 cervical cancer.
- High viral load was significantly associated with cervical intraepithelial neoplasia (CIN) and persistent infection (p < 0.001).
Conclusions:
- HPV73 single infection can progress to cervical cancer, though its pathogenicity is relatively low.
- High viral load is a critical factor in the persistence and pathogenicity of HPV73 infections.
- Further research is warranted to understand HPV73's role in cervical carcinogenesis.

01:26Stages of Infection
70.3K
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...

01:26Human Virome
54
The human body harbors a vast and diverse viral community known as the human virome. The virome includes bacteriophages that infect bacteria, and eukaryotic viruses that infect human cells. Transient dietary and environmental viruses also contribute to this dynamic ecosystem. Estimates suggest the human body may contain on the order of 10¹³ viral particles, though abundance varies widely by body site and detection method.Comprehensive characterization of the virome has become possible...

01:28Infectious Diseases and Their Occurrence
97
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...

01:23Investigation of Disease Outbreaks

Multistate foodborne outbreaks pose significant public health risks and require meticulous investigation to identify sources and implement control measures. The Centers for Disease Control and Prevention (CDC) utilizes a dynamic seven-step process for these investigations, integrating data from laboratories, interviews, and environmental assessments to protect public health.Outbreak Detection: The detection of multistate outbreaks typically begins with PulseNet, the CDC's national laboratory...

01:14Atypical Pneumonia
88
Atypical pneumonia, often caused by Mycoplasma pneumoniae, is a form of pulmonary infection that differs from the classical presentation of bacterial pneumonia in both its cause and clinical symptoms. Mycoplasma pneumoniae is a pleomorphic bacterium notable for its lack of a rigid cell wall. This structural characteristic imparts resistance to beta-lactam antibiotics and significantly influences the bacterium’s behavior within the human host.Other pathogens responsible for the disease...

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...
