    Winter conditions add to migrant hardship in northern Greece

    Freezing weather is exacerbating difficult conditions for migrants in overcrowded refugee camps in northern Greece. Last week the cold spell led to a protest by dozens of migrants at a camp near Thessaloniki. Greek officials have blamed the number of people flooding into the camp from the islands and across the Turkish border. But could the situation have been prevented?

    Harsh winter conditions hit northern Greece a few days into the new year, bringing sub-zero temperatures, strong winds, snow and ice. In the Diavata refugee camp near the port city of Thessaloniki, several hundred people are struggling with basic survival. Yet every week, despite the weather conditions, more continue to arrive.

    “They don’t think about this kind of thing, they just want to move on,” said one man at Diavata after another Afghan family arrived in the snow. “They just think that in the next stage from Turkey, when they go to Greece, everything will be fine.”

    Camp protests

    When they reach Diavata, the migrants find the reality is different. The camp is full to capacity, with around 800 registered asylum seekers. On top of these, there are between 500 and 650 people living at the site without having been registered by migration authorities.

    “Most of them have built their own makeshift shelters and tents, which are not providing them with the protection needed,” says Mike Bonke, the Greece country director of the Arbeiter Samariter Bund (ASB), an NGO providing support services to Diavata. “They have no (safe) heating, washing and sanitation and cooking facilities.”

    Last week, the difficult conditions prompted around 40 migrants to hold a protest outside the camp, burning tires and blockading the road. A truck driver tried to get through the barricade resulting in a fight which left one man in hospital.

    The driver lost his patience and started swearing at the migrants, who threw rocks and broke his windscreen, reports said. The driver and four migrants were charged with causing grievous bodily harm, according to the Greek daily, Katherimini.

    Conditions create health concerns

    Diavata is just one of a number of migrant facilities in northern Greece to have been affected by the cold snap. An NGO contacted by InfoMigrants said that Orestiada, near the Evros river to the east, was covered in snow. Migrants in the critically overcrowded camps on the islands too are contending with snow, frozen water pipes and icy roads.

    According to the ASB, the refugee reception camps lack resources to cope with the current conditions. “Healthcare services at all (refugee reception) sites are not adequate,” Bonke says.

    Agis Terzidis, an advisor to the Greek Minister of Health and Vice-President of the Center for Disease Control (CDC) which coordinates healthcare provision to migrants and refugees, admits that the cold weather, in addition to the poor conditions and overcrowding in the camps, is exacerbating migrants’ health problems. “We have people living in conditions that are not acceptable for anyone,” he says.

    National health system must step up

    In response to the worsening situation, there are plans to boost EU-funded medical teams operating in camps throughout the country, including the islands, Agis Terzidis says. But he told InfoMigrants that from now on, more pressure would be put on the Greek national health system and local hospitals to tackle the problem, rather than medical staff in the camps themselves.

    Terzidis also insisted that fixing the situation in the camps was “not in the mandate” of the CDC, as it was chiefly a result of greater numbers of people arriving and consequent overcrowding.

    Instead, the CDC’s main priority remains vaccinating migrants to prevent outbreaks of hepatitis, measles and other infectious diseases. It also focuses on treating those suffering from chronic diseases, some of whom will likely succumb to the harsh winter conditions.

    Too many people

    With more bleak weather predicted, a vegetable garden is being planned in the Diavata camp, giving the residents something to look forward to. That will have to be abandoned if more people start to arrive when the weather improves.

    The camps continue to be under pressure from the large and unpredictable numbers of arrivals. Currently there are around 20 arrivals per week at Diavata, but that could quickly escalate to hundreds. So far, Greek authorities do not seem to have taken steps to limit how many end up at the camps seeking protection.

    I think we can all agree that this situation should have been solved by registering these refugees in the Greek Migration system and providing them with dignified and safe shelters.
    _ Mike Bonke, Greece country director, Arbeiter Samariter Bund

    As both government and army staff and their NGO colleagues in the camps remain powerless to solve the problem of overcrowding, their main task will be to protect migrants from harm and exposure as the winter enters its coldest months.

  • Goldman asks: ’Is curing patients a sustainable business model?’
    https://www.cnbc.com/2018/04/11/goldman-asks-is-curing-patients-a-sustainable-business-model.html

    “Is curing patients a sustainable business model?” analysts ask in an April 10 report entitled “The Genome Revolution.”

    “The potential to deliver ’one shot cures’ is one of the most attractive aspects of gene therapy, genetically-engineered cell therapy and gene editing. However, such treatments offer a very different outlook with regard to recurring revenue versus chronic therapies,” analyst Salveen Richter wrote in the note to clients Tuesday. “While this proposition carries tremendous value for patients and society, it could represent a challenge for genome medicine developers looking for sustained cash flow.”

    (…) “GILD is a case in point, where the success of its hepatitis C franchise has gradually exhausted the available pool of treatable patients,” the analyst wrote. “In the case of infectious diseases such as hepatitis C, curing existing patients also decreases the number of carriers able to transmit the virus to new patients, thus the incident pool also declines … Where an incident pool remains stable (eg, in cancer) the potential for a cure poses less risk to the sustainability of a franchise.”

  • How Dirt Could Save Us From Antibiotic-Resistant Superbugs | WIRED
    https://www.wired.com/story/how-dirt-could-save-humanity-from-an-infectious-apocalypse

    Brady is creating drugs from dirt. He’s certain that the world’s topsoils contain incredible, practically inexhaustible reservoirs of undiscovered antibiotics, the chemical weapons bacteria use to fend off other microorganisms. He’s not alone in this thinking, but the problem is that the vast majority of bacteria cannot be grown in the lab—a necessary step in cultivating antibiotics.

    Brady has found a way around this roadblock, which opens the door to all those untapped bacteria that live in dirt. By cloning DNA out of a kind of bacteria-laden mud soup, and reinstalling these foreign gene sequences into microorganisms that can be grown in the lab, he’s devised a method for discovering antibiotics that could soon treat infectious diseases and fight drug-resistant superbugs. In early 2016, Brady launched a company called Lodo Therapeutics (lodo means mud in Spanish and Portuguese) to scale up production and ultimately help humanity outrun infectious diseases nipping at our heels. Some colleagues call his approach “a walk in the park.” Indeed, his lab recently dispatched two groups of student volunteers to collect bags full of dirt at 275 locations around New York City.

  • UN report urges end to inhuman detention of migrants in Libya

    The breakdown in the Libyan justice system has led to a state of impunity in which migrants are subjected to serious human rights violations and abuses, according to a joint UN human rights report published today.
    “People smuggled or trafficked into Libya face torture, forced labour and sexual exploitation along the route, and many also while held in arbitrary detention,” said Martin Kobler, the Secretary General’s Special Representative for Libya and Head of the UN Support Mission in Libya (UNSMIL).

    “The list of violations and abuses faced by migrants in Libya is as long as it is horrific. This is, quite simply, a human rights crisis affecting tens of thousands of people,” UN High Commissioner for Human Rights Zeid Ra’ad Al Hussein said.

    The report, published jointly by UNSMIL and the UN Human Rights Office, is based on information gathered in Libya and from interviews with migrants who had arrived in Italy from Libya, among other sources*.

    Migrants are held in detention centres mostly run by the Department for Combatting Illegal Migration (DCIM), where there is “no formal registration, no legal process, and no access to lawyers or judicial authorities,” the report states.
    Places of detention are severely overcrowded, with insufficient food and clean water. With no access to toilets, detainees are often forced to defecate and urinate in their cells. Malnutrition, acute diarrhoea, respiratory problems and infectious diseases, including scabies and chickenpox, are common.

    Smugglers and traffickers also hold migrants in “connection houses”, on farms and in warehouses and apartments, where they are forced to work to earn money for their onward transport.

    “We are called animals and are treated as animals,” a 16-year-old boy from Eritrea told UNSMIL. “They beat us with what falls into their hands…it can be a rock, a stick, a brick,” a child migrant interviewed in Italy said.
    The report also notes that DCIM and the Libyan Coast Guard** are subject to pressure from the armed groups that have proliferated since 2011. UNSMIL has received reports that some State employees and local officials have participated in the smuggling and trafficking process.

    The report also details accounts of armed men, allegedly from the Libyan Coast Guard, intercepting migrant boats and abusing migrants. Migrants brought back to shore describe being beaten, robbed and taken to detention centres.
    “Libya must acknowledge that migrants are being abused,” said Mr. Kobler. “But addressing migration is not only Libya’s responsibility. Countries of origin and destination beyond Libya also need to play their part.” He added: “I welcome the life-saving efforts currently being made by many in the Mediterranean.”

    Among the report’s recommendations to Libya are: immediately release the most vulnerable migrants, with a view to urgently ending all arbitrary detentions; reduce the number of detention centres; ensure women are held separately from men; improve conditions of detention and protect detainees from torture and all other forms of abuse; and, in the medium-term, decriminalize irregular migration and adopt an asylum law.

    The report also recommends that countries of destination beyond Libya continue search and rescue operations in the Mediterranean. Training and support for Libyan institutions that engage with migrants, including the Libyan Coast Guard, should be accompanied by comprehensive efforts to stop arbitrary detention of migrants and improve their treatment in detention.

    “These are people who, for a range of reasons, feel compelled to leave their own countries and embark on these desperate and precarious journeys. The report lays bare the suffering endured by these migrants who have experienced unimaginable abuse and, in some cases, fallen victim to the despicable trade in human lives,” said High Commissioner Zeid. “The report serves to deepen our compassion and strengthen our resolve that the rights of migrants should be fully protected and respected, whatever their status.”

  • Montreal disease experts tracking tropical infection in the Arctic | Montreal Gazette
    http://montrealgazette.com/news/local-news/montreal-disease-experts-tracking-tropical-infection-in-the-arctic

    A few years ago, several children in a remote northern Quebec community got very sick with intense diarrhea. Turns out they were infected with a dangerous bug more common in the tropics — but they caught the infection in the Canadian Arctic.

    The outbreak hit at least 10 villages in Nunavik, affecting mostly children. The culprit was a microscopic intestinal parasite called Cryptosporidium. It was discovered for the first time in Nunavik, Quebec, by a Montreal team of infectious diseases experts at the Research Institute of the McGill University Health Centre in 2013.

    Finding a tropical strain of Cryptosporidium in the Arctic where this disease was not previously known was a big surprise, said microbiologist Cédric Yansouni, the study’s senior author and McGill University professor in the division of infectious diseases in the medical microbiology department. The parasite is more common in developing countries in Africa and South America than in Canada.
    […]
    Researchers documented 69 cases between 2013 and 2014, mostly in children under age five. But the disease is likely under-reported because most people do not bother to get tested unless they are extremely sick, he said. There is no access to local testing and samples have to be sent nearly 2,000 kilometres south to Montreal.

    It’s not clear how such a tropical disease wended its way to remote communities in the Arctic or what caused the outbreak. Crypto lives in the intestines of mammals, including humans, and is usually spread by eating contaminated food, drinking water contaminated by feces, or through contact with infected individuals. Researchers tested the drinking water in the village where the outbreak began but found no contamination there. “We may never know how it got up there,” Yansouni said.

    “It’s unlikely that initial infection was acquired from animals or contaminated waterways in the region,” Yansouni said. But the good news is that the outbreak prompted efforts to speed diagnosis locally without having to ship samples to Montreal, he added.

  • Convicting Zika | The BMJ
    http://www.bmj.com/content/353/bmj.i1847

    Maintenant que les pseudo-liens avec les OGM et les produits chimiques se sont dégonflés, on ne parle plus beaucoup ici de #Zika, qui continue pourtant de provoquer des ravages au Brésil et dans un bassin de plus en plus large. Le consensus scientifique se renforce sur le rôle prééminent du virus dans l’épidémie de microcéphalie et autres pathologies flippantes, et qui touchent très majoritairement les pauvres. Avec l’équation jamais démentie et toujours renouvelée #virus + #moustiques + #inégalités = catastrophe sanitaire.

    The stream of new studies has even convinced some scientists who had been critical of the rush to judgment. In February, Glen Armstrong, professor of microbiology, immunology, and infectious diseases at the University of Calgary, cautioned against rushing to blame Zika, noting the link was based entirely on “circumstantial evidence.”7 But in an interview with The BMJ, he explained that while Zika’s link to microcephaly and other neurological disorders was still only a correlation, “I think the evidence is getting stronger and stronger in favour of the conclusion that the Zika virus is, if not the only major player, the major player.”

  • New research shows global warming’s effect on the quality of food available could kill more than 500,000 people a year around the world by 2050
    http://www.theguardian.com/environment/2016/mar/03/more-than-half-a-million-could-die-as-climate-change-impacts-diet-repor

    The research is the first to assess how the impacts of global warming could affect the quality of the diets available to people and found fewer fruit and vegetables would be available as a result of climatic changes. These are vital in curbing heart disease, strokes and diet-related cancers, leading the study to conclude that the health risks of climate change are far greater than thought.

    Climate change is already judged by doctors as the greatest threat to health in the 21st century, due to floods, droughts and increased infectious diseases, with the potential to roll back 50 years of progress.

Elle démontre le lien certain entre maladie neurologique grave et virus zika provoqué, lui, par une piqûre de moustique.

    • Guillain-Barré Syndrome outbreak associated with Zika virus infection in French Polynesia: a case-control study - The Lancet
      http://www.thelancet.com/journals/lancet/article/PIIS0140-6736(16)00562-6/abstract

      Summary
      Background
      Between October, 2013, and April, 2014, French Polynesia experienced the largest Zika virus outbreak ever described at that time. During the same period, an increase in Guillain-Barré syndrome was reported, suggesting a possible association between Zika virus and Guillain-Barré syndrome. We aimed to assess the role of Zika virus and dengue virus infection in developing Guillain-Barré syndrome.

      Methods
      In this case-control study, cases were patients with Guillain-Barré syndrome diagnosed at the Centre Hospitalier de Polynésie Française (Papeete, Tahiti, French Polynesia) during the outbreak period. Controls were age-matched, sex-matched, and residence-matched patients who presented at the hospital with a non-febrile illness (control group 1; n=98) and age-matched patients with acute Zika virus disease and no neurological symptoms (control group 2; n=70). Virological investigations included RT-PCR for Zika virus, and both microsphere immunofluorescent and seroneutralisation assays for Zika virus and dengue virus. Anti-glycolipid reactivity was studied in patients with Guillain-Barré syndrome using both ELISA and combinatorial microarrays.

      Findings
      42 patients were diagnosed with Guillain-Barré syndrome during the study period. 41 (98%) patients with Guillain-Barré syndrome had anti-Zika virus IgM or IgG, and all (100%) had neutralising antibodies against Zika virus compared with 54 (56%) of 98 in control group 1 (p<0·0001). 39 (93%) patients with Guillain-Barré syndrome had Zika virus IgM and 37 (88%) had experienced a transient illness in a median of 6 days (IQR 4–10) before the onset of neurological symptoms, suggesting recent Zika virus infection. Patients with Guillain-Barré syndrome had electrophysiological findings compatible with acute motor axonal neuropathy (AMAN) type, and had rapid evolution of disease (median duration of the installation and plateau phases was 6 [IQR 4–9] and 4 days [3–10], respectively). 12 (29%) patients required respiratory assistance. No patients died. Anti-glycolipid antibody activity was found in 13 (31%) patients, and notably against GA1 in eight (19%) patients, by ELISA and 19 (46%) of 41 by glycoarray at admission. The typical AMAN-associated anti-ganglioside antibodies were rarely present. Past dengue virus history did not differ significantly between patients with Guillain-Barré syndrome and those in the two control groups (95%, 89%, and 83%, respectively).

      Interpretation
      This is the first study providing evidence for Zika virus infection causing Guillain-Barré syndrome. Because Zika virus is spreading rapidly across the Americas, at risk countries need to prepare for adequate intensive care beds capacity to manage patients with Guillain-Barré syndrome.

  • Progress and Challenges in Infectious Disease Cartography

    http://www.sciencedirect.com/science/article/pii/S147149221500207X

    Payant, mais je référence parce que potentiellement très intéressant pour @fil en particulier et @visionscarto en général

    Quantitatively mapping the spatial distributions of infectious diseases is key to both investigating their epidemiology and identifying populations at risk of infection. Important advances in data quality and methodologies have allowed for better investigation of disease risk and its association with environmental factors. However, incorporating dynamic human behavioural processes in disease mapping remains challenging. For example, connectivity among human populations, a key driver of pathogen dispersal, has increased sharply over the past century, along with the availability of data derived from mobile phones and other dynamic data sources. Future work must be targeted towards the rapid updating and dissemination of appropriately designed disease maps to guide the public health community in reducing the global burden of infectious disease.

  • Corrupted Blood incident
    https://en.wikipedia.org/wiki/Corrupted_Blood_incident#cite_ref-c.26vg_9-3

    The Corrupted Blood incident was a video game glitch and virtual plague in the MMORPG World of Warcraft, which began on September 13, 2005, and lasted for one week. The epidemic began with the introduction of the new raid Zul’Gurub and its end boss Hakkar The Soulflayer. When confronted and attacked, Hakkar would cast a hit point-draining and highly-contagious debuff spell called Corrupted Blood on players.

    In March 2007, Ran D Balicer, an epidemiologist physician at the Ben-Gurion University of the Negev in Bersheva, Israel, published an article in the journal Epidemiology that described the similarities between this outbreak and the recent SARS and avian influenza outbreaks. Dr Balicer suggested that role-playing games could serve as an advanced platform for modeling the dissemination of infectious diseases. In a follow-up article in the journal Science, the game Second Life was suggested as another possible platform for these studies. The Centers for Disease Control and Prevention contacted Blizzard Entertainment and requested statistics on this event for research on epidemics but was told that it was a glitch.

  • Is it the visualisation or the data we like? - Visualising Data

    thought for the day. Stick with me on this, I’m still deciding if there’s something in it: I will only know after I’ve published it though so here goes.

    I’m musing about this visualisation work that has received a lot of love and attention on blogs and social media over the past few days. Created by the excellent people in the Wall Street Journal graphics team, it portrays data about the impact of vaccines in battling infectious diseases in the 20th Century.

    The chart that has had the most impact, due to the highly topical nature of its subject, is the measles chart. This was certainly the image that was drew me in and was used to accompany the many positive tweets it received.

    My question is this: do we like the visualisation or do we like the data?
