Gene Analysis Of Yemen Cholera Proves | By Dr Patricia Doyle PhD |
Hello Jeff ... The genetic finding that the huge Cholera outbreak that has sickened and/or killed over a million people in Yemen was brought to Yemen from Eastern Africa should alarm everyone. Sub-Saharan black African migration is spreading dozens of dangerous and deadly diseases into Europe, the Mideast and the US.
Here is more proof that Third World 'refugees' and 'migrants' are spreading diseases wherever they go... Genetic analysis of Vibrio cholerae samples from Yemen's cholera outbreak, which has sickened more than 1 million people and is the largest in recent history, suggests the strain came from eastern Africa and entered the country by migration in and out of the region, researchers from the Wellcome Sanger Institute and Pasteur Institute reported yesterday in Nature . Yemen had two waves in its cholera outbreak: one between September 2016 and April 2017 and another that began later in April 2017. The outbreaks have been linked to at least 2,500 deaths. The team sequenced 42 samples collected in Yemen and a refugee center at the Saudi Arabia border and compared them with a global collection of more than 1,000 samples from a current and ongoing pandemic, which has been under way since the 1960s and is caused by a single V cholerae lineage, 7PET. The strain fueling Yemen's outbreak is similar to one first seen in South Asia in 2012 that has spread globally, but it didn't arrive directly from South Asia or the Middle East. Before arriving in Yemen, the strain was circulating and triggering outbreaks in eastern Africa in 2013 and 2014. Experts had thought that Yemen's outbreaks were caused by two different strains, but the study found they were caused by the same one that entered Yemen in 2016. Another unexpected finding was that Yemen's cholera strain is susceptible to many antibiotics - most that trigger epidemics are resistant to several antibiotics. Marie-Laure Quilici, PhD, with the Pasteur Institute, said in a Wellcome Trust press release, "This study illustrates again the key role of genomic microbial surveillance and cross-border collaborations in understanding global cholera spread."
