Malaria01:29

Malaria

Malaria pathogenesis in humans reflects a delicate interplay between parasite biology and host response. Clinical illness reflects a host’s immune response to the parasite’s asexual replication cycle, which is often asymptomatic in individuals with partial immunity. From the parasite's perspective, transmission between mosquito and human with minimal host pathology is evolutionarily advantageous. Among the six Plasmodium species infecting humans, P. falciparum and P. vivax dominate in global...
Infectious Diseases and Their Occurrence01:28

Infectious Diseases and Their Occurrence

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 temporal or...
Microbes and Climate Change01:27

Microbes and Climate Change

Microorganisms are pivotal agents in Earth's biogeochemical cycles, significantly influencing climate dynamics through their metabolic activities. These microbes modulate the levels of key greenhouse gases by both contributing to and helping mitigate climate change.Microbial Contributions to Greenhouse Gas EmissionsRising global temperatures accelerate microbial metabolism, which, in turn, speeds up the decomposition of organic matter. This process releases carbon dioxide (CO₂) through...
Influenza01:27

Influenza

Influenza is an acute, highly communicable viral disease that affects the respiratory tract and is responsible for seasonal epidemics worldwide. Influenza A is the most prevalent type associated with widespread outbreaks and is subtyped based on two surface glycoproteins: hemagglutinin (H) and neuraminidase (N), as in H1N1. These glycoproteins are essential for viral infectivity, transmission, and immune recognition. Transmission occurs primarily through respiratory droplets and contaminated...
Investigation of Disease Outbreaks01:23

Investigation 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...
Yellow Fever01:18

Yellow Fever

Yellow fever is a viral hemorrhagic disease caused by the yellow fever virus (YFV), a member of the Flaviviridae family. It is transmitted primarily by Aedes and Haemagogus mosquitoes in tropical and subtropical regions of Africa and South America. After transmission through a mosquito bite, the virus initially replicates in skin-resident immune cells such as dendritic cells and macrophages. These cells then migrate to the lymph nodes, where viral replication increases, eventually leading to...

Summary

Dengue incidence in Puerto Rico remained stable despite global warming, influenced by rainfall, healthcare, and population changes. Future increases are possible due to rising temperatures and climate change.

Area of Science:

  • * Epidemiology
  • * Climate Science
  • * Public Health

Background:

  • * Dengue fever is a significant insect-borne disease with complex transmission dynamics.
  • * Understanding the influence of climatic variables on dengue incidence is crucial for public health planning.

Purpose of the Study:

  • * To investigate the relationship between climatic variables (temperature, precipitation) and dengue variability in Puerto Rico from 1979 to 2005.
  • * To analyze long-term trends and project potential future impacts of climate change on dengue epidemics.

Main Methods:

  • * Comparison of annual and monthly reported dengue cases with historical precipitation and temperature data.
  • * Analysis of seasonal fluctuations and year-to-year variability in dengue cases.
  • * Mapping of climatic conditions against dengue case data and comparison of epidemic patterns.

Published on: April 28, 2019

Main Results:

  • * Dengue incidence remained relatively constant over the study period, despite global warming, due to factors like declining rainfall and improved healthcare.
  • * Seasonal dengue peaks correlated with increased rainfall from May to November.
  • * Year-to-year dengue variability showed a weak positive association with temperature and El Niño Southern Oscillation (ENSO) index, and a weak association with rainfall.

Conclusions:

  • * While past dengue incidence was stable, future increases are anticipated due to rising Caribbean temperatures and global warming trends.
  • * Climate forecasts are essential for anticipating dengue epidemics and mitigating adverse health impacts.
  • * Continued monitoring and adaptive public health strategies are necessary to address the evolving threat of dengue.
