Abstract

Insights

The COVID-19 pandemic worsened antimicrobial resistance (AMR) by disrupting infection control and increasing multidrug-resistant organisms (MDROs). Strategic responses, like those in Taiwan, are crucial to combat this escalating global health threat.

Area of Science:

  • Global Health
  • Infectious Diseases
  • Microbiology

Background:

  • The COVID-19 pandemic created significant global health challenges.
  • Healthcare systems faced immense strain, impacting infection control and antimicrobial stewardship.
  • This led to an accelerated spread of antimicrobial resistance (AMR) and multidrug-resistant organisms (MDROs).

Purpose of the Study:

  • To review the indirect effects of the COVID-19 pandemic on AMR.
  • To analyze changes in antibiotic utilization, healthcare-associated infections, and resistance trends.
  • To present epidemiological data, focusing on Taiwan's MDRO landscape and responses.

Main Methods:

  • Review of global and regional epidemiological data on AMR and MDROs.
  • Analysis of antibiotic utilization patterns during the pandemic.
  • Case study examination of Taiwan's strategies and outcomes.

Main Results:

  • The pandemic exposed and intensified vulnerabilities in AMR control.
  • Disrupted antimicrobial oversight led to increased MDRO prevalence.
  • Taiwan's experience highlights the effectiveness of coordinated guidelines and AI-driven stewardship.

Conclusions:

  • Multidrug-resistant organisms (MDROs) pose a significant post-pandemic threat.
  • Integrated global policies, sustained surveillance, and innovation are essential for future AMR responses.
  • Taiwan's strategic approach offers valuable lessons for combating AMR.

Threats to Biodiversity

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...

Stereotype Threat and Self-fulfilling Prophecies02:09

Stereotype Threat and Self-fulfilling Prophecies

When we hold a stereotype about a person, we have expectations that he or she will fulfill that stereotype. A self-fulfilling prophecy is an expectation held by a person that alters his or her behavior in a way that tends to make it true. When we hold stereotypes about a person, we tend to treat the person according to our expectations. This treatment can influence the person to act according to our stereotypic expectations, thus confirming our stereotypic beliefs. Research by Rosenthal and...

Global Climate Change

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.

Impact of Groups on Groups

Social psychologists analyze how groups influence one another, shaping social structures and interactions through both cooperation and competition. These dynamics manifest in various ways, ranging from economic partnerships to intergroup conflicts that shape societal structures and perceptions.Cooperation and Competition in Intergroup RelationsIntergroup relationships vary across contexts, sometimes fostering cooperation and mutual benefit while at other times leading to conflict and...

Resistivity01:22

Resistivity

When a voltage is applied to a conductor, an electrical field is generated, and charges in the conductor feel the force due to the electrical field. The current density that results depends on the electrical field and the properties of the material. In some materials, including metals at a given temperature, the current density is approximately proportional to the electrical field. In these cases, the current density can be modeled as:
