New way to detect human-animal diseases tested in lemurs
(Duke University) RNA sequencing is uncovering emerging diseases in wildlife that other diagnostic tests cannot detect. Researchers used a technique called transcriptome sequencing to screen for blood-borne diseases in Madagascar's lemurs, distant primate cousins to humans. The animals were found to be carrying several previously unknown parasites similar to those that cause Lyme disease in humans. The approach could pave the way for earlier, more accurate detection of disease outbreaks that move between animals and people.
A team of researchers found that by analyzing trends on Google searches and Twitter, they can predict vaccination scares that could eventually lead to disease outbreaks.

[MSF] Ugandan authorities have declared the end of the Marburg fever outbreak that has affected the eastern part of the country since October. MSF provided support to local authorities, in particular in case management capacity and epidemic surveillance. MSF, the Ugandan Ministry of Health and their partners have also introduced new tools which will improve case management in future haemorrhagic fever outbreaks.
JAKARTA (Reuters) - Health authorities in Jakarta kicked off a special immunization program on Monday to rein in an "extraordinary" outbreak of diphtheria that has sparked concerns about the Indonesian capital ’s readiness to host the Asian Games next June. Diphtheria cases have spiked 42 percent since last year, health officials say, with at least 32 deaths and more than 590 cases recorded across the archipelago, the bulk of them in densely populated Jakarta and neighboring provinces.

Publication date: Available online 10 December 2017 Source:Ticks and Tick-borne Diseases Author(s): Christine B. Graham, Sarah E. Maes, Andrias Hojgaard, Amy C. Fleshman, Sarah W. Sheldon, Rebecca J. Eisen The incidence and geographic range of tick-borne illness associated with Ixodes scapularis and Ixodes pacificus have dramatically increased in recent decades. Anaplasmosis, babesiosis, and Borrelia spirochete infections, including Lyme borreliosis, account for tens of thousands of reported cases of tick-borne disease every year. Assays that reliably detect pathogens in ticks allow investigators and public health agencie...
ConclusionsImproving best practices and particularly hand hygiene proved effective in terminating the outbreak. Whole genome sequencing is a helpful tool for genotyping because it allows both sufficient discrimination of strains and comparison to other outbreaks through the use of an emerging international database.
By Megan Molteni for WIRED. First comes the unscratchable itching, and the angry blossoming of hives. Then stomach cramping, and — for the unluckiest few — difficulty breathing, passing out, and even death. In the last decade and a half, thousands of previously protein-loving Americans have developed a dangerous allergy to meat. And they all have one thing in common: the lone star tick. Red meat, you might be surprised to know, isn’t totally sugar-free. It contains a few protein-linked saccharides, including one called galactose-alpha-1,3-galactose, or alpha-gal, for short. More and more people are lear...
Zika virus, Ebola, Middle East Respiratory Syndrome (MERS) coronavirus, Severe Acute Respiratory Syndrome (SARS) coronavirus, Nipah virus, Hendra virus, bird flu, swine flu -- these viruses have all grabbed international attention in recent years. In the past few decades the world has witnessed an alarming surge in emerging infectious diseases (EIDs). Since 1980, new pathogens have emerged in the human population at a rate of about three each year. Why are we seeing such a surge in new pathogens? One could argue that some of the pathogens may not be new at all; they could have circulated among humans for centuries and are...
