Marine pathogens spread much faster than their terrestrial counterparts
It has become increasingly clear that pathogen epidemics are as significant a component of marine systems as they are in terrestrial systems. At an NCEAS working group on Diseases in the Ocean, McCallum et al collated data on epidemic spread from both environments. Their analysis in Ecology Letters, December, shows marine epidemics spread about 100 times faster than comparable terrestrial epidemics, warning that emerging diseases may pose particularly severe threats to marine ecosystems.

Climate and cholera
Cholera outbreaks may soon be predicted using satellite sensors, paving the way for preemptive medicine in countries that suffer epidemics, says Distinguished University Professor Rita Colwell, speaking Wednesday, April 2, 2008, at the Society for General Microbiology's 162nd meeting being held this week at the Edinburgh International Conference Center. (2008-04-01)

New model for epidemic contagion
Humans are considered the hosts for spreading epidemics. The speed at which an epidemic spreads is now better understood thanks to a new model accounting for the provincial nature of human mobility, according to a study published in European Physical Journal B. The research was conducted by a team lead by Vitaly Belik from the Massachusetts Institute of Technology, USA, who is also affiliated with the Max Planck Institute for Dynamics and Self-Organization, Germany.

Regional trends in overdose deaths reveal multiple opioid epidemics, according to new study
A recently published study shows the United States in the grip of several simultaneously occurring opioid epidemics, rather than just a single crisis. The epidemics came to light after the researchers analyzed county-level data on drug overdose deaths. The study highlights the importance of different policy responses to the epidemics rather than a single set of policies. (2019-12-09)

US syphilis epidemics not driven by increases in unsafe sex say researchers
A UK based team of researchers has found that regular epidemics of syphilis in the USA are due to the intrinsic cyclical nature of the disease. They show that changes in the immunity of the population cause periodic syphilis outbreaks, rather than changes in sexual behaviour, as was previously thought. (2005-01-26)

Resampling of hard-hit region suggests amphibians may be developing resistance to deadly fungus
As amphibian populations globally continue to be ravaged by chytridiomycosis, a disease caused by a deadly fungal pathogen, a new study suggests that some populations in Panama may have started becoming more resistant to the fungus about a decade after it began significantly impacting them. (2018-03-29)

The role of the Sun in the spread of viral respiratory diseases
Why do most viral epidemics spread cyclically in autumn and winter in the globe's temperate regions? According to an interdisciplinary team of researchers of the Italian National Institute for Astrophysics, the University of Milan, the Lombardy regional agency for the environment and the Don Gnocchi Foundation, the answer is intimately related to our Sun (2020-11-02)

Evolving to fight epidemics: Weakness can be an advantage
When battling a deadly parasite epidemic, less resistance can sometimes be better than more, a new study suggests. A freshwater zooplankton species known as Daphnia dentifera endures periodic epidemics of a virulent yeast parasite that can infect more than 60 percent of the Daphnia population. (2012-03-30)

New mathematical model explains changing patterns in epidemics
A simple, new mathematical model enables scientists to predict epidemics of infectious diseases such as measles. A team of researchers from the University of Florida, University of Cambridge in Cambridge, England and McMaster University in Hamilton, Ontario, Canada developed the model and applied it to measles epidemics. (2000-01-26)

Bacterial 'gene swapping' sparks disease outbreaks
A new study by scientists at the University of Liverpool documents, for the first time, how the ability of bacteria to swap genetic material with each other can directly affect the emergence and spread of globally important infectious diseases. (2018-04-17)

New model for early meningitis detection
A meningitis incidence threshold of 10 cases per 100 000 inhabitants in just 1 week - lower than previously recommended by the WHO - can reliably be used to confirm an epidemic in time to implement vaccination programmes, conclude authors of a study in this week's issue of THE LANCET. (2001-07-26)

Computer model shows US vulnerable to MDR-TB epidemic
While the US has made great progress in the prevention and treatment of tuberculosis, the nation has become more susceptible to potential epidemics of multidrug-resistant tuberculosis, or MDR-TB, according a study led by Johns Hopkins researchers. Computer simulations show that as TB prevalence falls, the risk for more extensive MDR-TB increases. In addition, the simulation also showed that higher detection of TB cases without proper treatment of cases also increased risk. (2010-09-27)

Drought identified as key to severity of West Nile virus epidemics
A study led by UC Santa Cruz researchers has found that drought dramatically increases the severity of West Nile virus epidemics in the United States, although populations affected by large outbreaks acquire immunity that limits the size of subsequent epidemics. (2017-02-07)

Charting the course of the current cholera pandemic throughout Africa and Latin America
François-Xavier Weill and colleagues used expansive genomic data to chart the course of the seventh -- and current -- cholera pandemic throughout its most affected continent, Africa. (2017-11-09)

Weakness can be an advantage in surviving deadly parasites, a new study shows
When battling an epidemic of a deadly parasite, less resistance can sometimes be better than more. A new study suggests that a lake's ecological characteristics influence how freshwater zooplankton Daphnia dentifera evolve to survive epidemics of a virulent yeast parasite Metschnikowia bicuspidate. The study found that Daphnia populations evolved either enhanced resistance or susceptibility to infection depending on the nutrient concentration and predation levels in the lake. (2012-03-29)

Circulation of 'disaster myths' in Haiti could hinder appropriate disposal of bodies
Myths about the infectious disease threat posed by dead bodies could lead to insensitive and inappropriate treatment of victims' bodies following the floods in Haiti, and need to be checked, according to a public health researcher who has studied the potential risks at length. (2004-09-30)

Africa in the path of COVID-19
In a New England Journal of Medicine paper, researchers urge a coordinated global effort in the face of the COVID-19 pandemic, with countries around the world [taking] concrete steps to assist Africa in staying ahead of the curve, even as they confront their own epidemics. (2020-04-17)

Selective predation and productivity jointly drive complex behavior in host-parasite systems
Spencer R. Hall, Meghan A. Duffy, and Carla E. Cáceres studied a simple model which shows how predators that strongly prefer parasitized hosts can introduce (2005-02-02)

Could sugar be responsible for the obesity and diabetes epidemics?
The idea that sugar could be a fundamental cause of the global obesity and diabetes epidemics, with deleterious effects on the human body that go beyond just empty calories, should be considered seriously again, argues journalist and author Gary Taubes in The BMJ today. (2018-01-03)

Researchers trace dynamics of measles epidemics
Infectious diseases and epidemics are the nightmares of bioterrorism, but a team of researchers is investigating historic measles epidemics to better understand the dynamics of disease spread. (2001-12-12)

Modeling the trajectory of COVID-19 cases in settings with weaker health systems
A new modeling study evaluating unfolding COVID-19 epidemics among different income countries reports that, in lower income countries, even if risk is reduced because populations are younger, this benefit is largely negated by limited health system capacity and closer inter-generational contact. (2020-06-12)

El Niño conditions in the Pacific precedes dengue fever epidemics in South Asia
Researchers have found a strong association between El Niño-Southern Oscillation conditions in the Pacific to observed weather and dengue epidemics in Sri Lanka. According to a study published in the International Journal of Environmental Research and Public Health, el Niño activity -- measured in sea surface temperature in the pacific -- impacts rainfall and temperatures in Sri Lanka and thus contributes to exacerbated dengue epidemics six months later. (2016-11-21)

Emerging HIV epidemics among people who inject drugs in the Middle East and North Africa
HIV epidemics are emerging among people who inject drugs in several countries in the Middle East and North Africa. Though HIV infection levels were historically very low in the Middle East and North Africa, substantial levels of HIV transmission and emerging HIV epidemics have been documented among people who inject drugs in at least one-third of the countries of this region, according to findings published today in PLOS Medicine. (2014-06-19)

Small seasonal changes can lead to big flu outbreaks
Flu season is on its way to homes across North America. But the question of why influenza epidemics take place in the few cold months of winter remains unanswered. The answer may be extremely minute seasonal changes, says David Earn of McMaster University. Earn, who uses mathematical models to investigate and understand how infectious diseases move through populations, recently examined the question of why most people catch the flu in the winter. (2004-11-15)

Forecasting dengue: Challenges and a way forward
International collaboration is finding new ways to improve how scientists develop and test models to forecast dengue infection. (2019-11-11)

Age groups that sustain resurging COVID-19 epidemics in the United States
By late summer 2020, the resurgence of COVID-19 in the United States was largely driven by adults between the ages of 20 and 49, a new study finds. (2021-02-02)

A single mutation in Zika virus results in microcephaly
One single genetic change, likely acquired in 2013, gave the Zika virus the ability to cause severe fetal microcephaly, researchers report. (2017-09-28)

Warning: Epidemics are often followed by unrest
History teaches that social tension accumulated over an epidemic can lead to significant episodes of rebellion, according to a study. (2020-09-07)

Study of social contact patterns in Hong Kong will give insight into spread of epidemic
The first ever long-term study of patterns of social contact in Hong Kong will improve our knowledge of the growth of epidemics. Hong Kong was where SARS emerged in 2002-2003. The study looked at the number and type of social encounters made by 1,450 residents. This is affected by age but 'supermixers' are not necessarily more likely to contract or spread disease. (2018-02-01)

Falling birth rates shift rotavirus epidemics
Fewer births in states such as California may be delaying the annual onset of a common intestinal virus in the southwest, according to epidemiologists. The timing of infectious outbreaks in other locations such as the northeast remains more or less unchanged. (2009-07-16)

Vulnerability to Ebola and Lassa fever can now be properly assessed
Identifying vulnerabilities to outbreaks of Ebola and Lassa fever is possible following new research from the University of Surrey and University of Cambridge. This will aid government agencies and health organisations in evaluating a country's vulnerability to outbreaks, and inform decisions on strategic investments and plans. (2019-06-04)

The swine flu pandemic
A special issue of Deutsches Arzteblatt International contains the first scientific presentation of clinical experience with the novel influenza A virus (H1N1/09) in the German-speaking countries since the start of the pandemic. (2009-12-03)
