Infection01:20

Infection

9.3K
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...

Steps in Outbreak Investigation01:18

Steps in Outbreak Investigation

258
In the ever-evolving field of public health, statistical analysis serves as a cornerstone for understanding and managing disease outbreaks. By leveraging various statistical tools, health professionals can predict potential outbreaks, analyze ongoing situations, and devise effective responses to mitigate impact. For that to happen, there are a few possible stages of the analysis:

Viral Recombination00:57

Viral Recombination

24.0K
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.

Prevalence and Incidence01:08

Prevalence and Incidence

965
In statistical epidemiology and health sciences, two essential metrics—prevalence and incidence—are fundamental for understanding disease dynamics within a population. These measures enable public health officials, epidemiologists, and researchers to assess the burden of diseases, allocate resources effectively, and design impactful public health policies and interventions.
Prevalence indicates the proportion of individuals in a population who have a specific disease or health...

Healthcare Associated Infections II: Preventive Measures01:22

Healthcare Associated Infections II: Preventive Measures

3.2K
Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.
The best practices for preventing healthcare-associated infections include hand hygiene, patient risk...

Transmission-based Precautions I: Contact, Enteric, and Droplets01:17

Transmission-based Precautions I: Contact, Enteric, and Droplets

4.2K
Transmission-based precautions are for patients known to be infected or suspected to be infected or colonized with organisms that pose a significant risk to others. Some transmission-based precautions include contact, enteric, and droplet.
Contact Precautions:
Contact precautions are the measures taken to prevent the transmission of infectious agents, especially epidemiologically important microorganisms such as MRSA or influenza, primarily transmitted through direct or indirect contact with an...

    Area of Science:

    • Veterinary Public Health
    • Epidemiology
    • One Health

    Background:

    • Global livestock sector expansion and intensification heighten epidemic disease risks.
    • Increased wildlife-human and wildlife-livestock contact, driven by anthropogenic changes, facilitates disease spillover.
    • Weak biosecurity in global livestock value chains contributes to the spread of infectious diseases.

    Purpose of the Study:

    • To highlight the critical role of Veterinary Services in preventing and controlling epidemic diseases in the livestock sector.
    • To identify key areas for improving Veterinary Services' capacity to address emerging infectious disease threats.
    • To emphasize the need for integrated, whole-of-society approaches to disease management.

    Main Methods:

    • Analysis of disease emergence drivers in livestock.
    • Review of the impact of livestock system intensification and globalization.
    • Identification of essential functions and improvements for Veterinary Services.

    Main Results:

    • Livestock epidemics are linked to intensified farming and global trade with inadequate biosecurity.
    • Past epidemics have caused significant economic losses, with COVID-19 demonstrating broader socio-economic consequences.
    • Veterinary Services are vital for early detection and control of zoonotic diseases.

    Conclusions:

    • Veterinary Services require enhanced capacity in risk assessment, value chain analysis, and communication.
    • Adaptation of control strategies for resource-poor settings and improved multi-sectoral cooperation are essential.
    • Systematic approaches are needed for Veterinary Services to influence national and regional decision-making across various sectors.
