Infection01:20

Infection

7.9K
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...

Global Climate Change

24.4K
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

Steps in Outbreak Investigation

128
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

23.4K
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.

Threats to Biodiversity01:50

Threats to Biodiversity

22.3K
There have been five major extinction events throughout geological history, resulting in the elimination of biodiversity, followed by a rebound of species that adapted to the new conditions. In the current geological epoch, the Holocene, there is a sixth extinction event in progress. This mass extinction has been attributed to human activities and is thus provisionally called the Anthropocene. In 2019 the human population reached 7.7 billion people and is projected to comprise 10 billion by...

Viral Mutations00:36

Viral Mutations

32.3K
A mutation is a change in the sequence of bases of DNA or RNA in a genome. Some mutations occur during replication of the genome due to errors made by the polymerase enzymes that replicate DNA or RNA. Unlike DNA polymerase, RNA polymerase is prone to errors because it is not capable of “proofreading” its work. Viruses with RNA-based genomes, like HIV, therefore accrue mutations faster than viruses with DNA-based genomes. Because mutation and recombination provide the raw material...

Area of Science:

  • Disease ecology
  • Global change research
  • One Health

Background:

  • Human activities are driving rapid planetary changes, impacting all life.
  • Emergence and spread of infectious diseases into new populations are increasing.
  • Global change factors (climate, land use, urbanization, trade) interact with socioeconomic elements to accelerate disease emergence.

Purpose of the Study:

  • To review how global change drives disease emergence from a disease ecology perspective.
  • To identify mechanisms and approaches linking global change to disease emergence.
  • To promote interdisciplinary collaboration with economists for sustainable interventions.

Main Methods:

  • Review of existing literature on global change and disease ecology.
  • Analysis of mechanisms by which ecological systems are reshaped by global change.
  • Examination of socioeconomic factors influencing disease emergence.

Main Results:

  • Global change significantly reshapes ecological systems, creating conditions conducive to disease emergence.
  • Interactions between environmental changes and socioeconomic factors are key drivers.
  • Disease emergence mechanisms are system-specific, varying across different contexts.

Conclusions:

  • Integrated approaches are needed to control infectious diseases, recognizing links between environmental and economic sustainability.
  • Sustainable interventions require understanding the complex interplay between human activities, ecological systems, and disease dynamics.
  • Future efforts must foster collaboration across disciplines to address the One Health challenge.
