A nightmare in Liberia. - http://clapway.com/2015/06/30/ebola-is-back-liberian-village-under-quarantine-234/

After Liberia was declared Ebola-free six weeks ago, a body of a dead citizen was tested positive for the virus, plunging a village into quarantine. That’s right — Ebola is back.


Deputy health minister, Tolbert Nyenswah said tests confirmed that Ebola is back after the deceased 17-year-old man, from a town near the main airport, had died of the disease. The conditions under which the young man contracted Ebola are still uncertain.


First case of Ebola in Liberia since country declared virus-free


Early investigations suggest that the boy was found in Margibi County among the worst impacted areas during the previous outbreak. A team collected bodily fluid, and the village where the boy was from was immediately placed under quarantine to prevent further infections. The body was buried according to anti-Ebola safety guidelines.


According to the BBC, this is the country’s first reported case since the World Health Organization (WHO) declared Liberia virus-free in May.


In Guinea, Ebola infections persist


Ebola is back in Liberia, but in Guinea, it had not even left. The boy fell ill June 21, died three days later in a region close to Guinea, where Ebola infections continue to persist.


In May 2015, cases of Ebola began to appear in Tanene, Dubreka Prefecture, Guinea. This is an area that had previously been unaffected.


The international health community is now doing its best to ensure that the outbreak remains limited to that area. The World Health Organization (WHO) and partners have launched a surveillance campaign to find individuals who might be infected while providing support to families.


Around 20 to 27 weekly cases of Ebola


According to WHO statistics, since the end of May, the weekly case incidence of Ebola appears to have stalled at between 20 and 27 cases .


More than 11,000 people have died of the disease since the outbreak in West Africa. The vast majority of the victims were found in Guinea, Liberia, and Sierra Leone. Experts fear that with the start of the rainy season, the number of cases will rise.


Cases continue to arise from unknown sources of infection, and to be detected only post-mortem. The international health community, has mobilized its largest response to what has been labeled “the most severe and most complex outbreak in the history of this disease”.

Ebola Is Back -- Liberian Village Under Quarantine

Forget smartphones? Here"s a s small, smart DNA sequencer. - http://clapway.com/2015/06/15/game-changer-dna-sequencer-the-size-of-a-smartphone-325/

Researchers in Canada and the U.K. have sequenced and assembled de novo, the first full genome of a living organism using a DNA sequencer that can fit in your pocket. If when you hear the word ‘minion’ you think of those small yellow creatures in the upcoming computer-animated comedy film ‘Minions’, you will be surprised by what you read next…


It could turn out to be a significant scientific leap forward: a team of scientists has used a mobile-phone-sized DNA sequencer called MinION to assemble a complete bacterial genome. Hard to imagine if we consider competing machines that can be as big as closets.


A REVOLUTION IN DNA-BASED DIAGNOSTICS


The cost-effective device, which has already been used by epidemiologists to read the genomes of Ebola viruses in West Africa and sequence patient DNA, will trigger what some have called a “democratization” of sequencing. Experts believe that with the combination of affordability, long-reads and portability, this USB thumb-drive genetic testing device, is primed to disrupt the way scientists do genomics.


Findings published today in the journal Nature Methods suggest that the DNA sequencer marketed by Oxford Nanopore allows room to scale up and sequence larger and more complex samples of genomes in organisms, eventually including human beings.


CHEWING GUM PACKET-SIZED DNA SEQUENCER


According to Dr. Jared Simpson, Principal Investigator at the Ontario Institute for Cancer Research, this chewing gum packet-sized DNA sequencer is designed to generate real-time data streaming and read long enough stretches of the genome allowing complete reconstructions off a tiny device.


Although some scientists don’t see the groundbreaking adoption of the device at a clinical level, the MinION definitely has an amazing ‘hip’ factor since it is so small and portable, and could be a game-changer due to its relatively affordable price. Traditional sequencers could cost as much as US $1 million, while researchers could use this DNA sequencer for a US$1,000 deposit.


Dr. Tom Hudson, President and Scientific Director of the Ontario Institute for Cancer Research believes that the technology has incredible potential. If scaled up, it could sequence tumour genomes and deliver tailor-made diagnosis and treatment to patients across the globe.


A shortcoming of the technology is that the single reads it produces are currently much less accurate than the reads produced by larger devices. Yet, with a jump in accuracy to match its competitors, this DNA sequencer has the potential to be used by scientists as an alternative or supplement to current options.



 
Eventually we’ll neeed Urban Armor Gear for our smart, portable DNA sequencers (one hopes):
