While the full size and scope of China's African swine fever (ASF) epizootic remains frustratingly undefined - and the long-term impacts are largely unknowable - the uncontrolled spread of ASF across Asia could have serious impacts that extend far beyond economic losses for pork producers and a switch to alternative proteins for consumers.
Streptococcus suis has recently re-emerged as a significant cause of increased mortality in piglets and growing pigs.
The study revealed extensive genetic diversity as well as spatial dispersal of EEEV within Florida. Additionally, Das and colleagues observed more clustering of the disease in the Panhandle region. The findings, they said, indicate that EEEV is present year-round in the Florida Panhandle and that the region could be “seeding” EEEV epizootics in the rest of the state and the Northeastern US.
Melvin Sanicas, MD, a Japanese encephalitis vaccinologist, discusses the disease.
Research shows that Zika virus has circulated at a low but sustained level for at least 16 years, suggesting that Zika virus can adapt to persistent endemic transmission. Health systems need to adapt to cope with regular occurrences of the severe complications associated with infection.
A 19th-century doctor famously mapped cholera’s toll to try and understand its origin and spread—but that's only part of the story.
There are no studies on coronaviruses (CoV) of bats, nor in humans in Colombia and Latin America. This lack of information in a country that holds the greatest diversity of Chiroptera in the region, reveals an ecoepidemiological gap that we have to overcome with the implementation of more studies aimed at better understanding the role of CoV in human health and animal in the region and in the world.
This study highlights the potential of combining traditional surveillance with portable genome sequencing technologies and digital epidemiology to inform public health surveillance in the Amazon region.
One mystery about anthrax is why outbreaks are so different across the planet. In some areas outbreaks occur annually with few cases, while in other areas explosive outbreaks occur with decades or longer in between.
African Swine Fever (ASF) made its entrance into Western Europe as well as China this fall, causing a lot of nervousness amongst pig professionals worldwide. Pig Progress editor Vincent ter Beek enquired with ASF experts in various countries.
