Covid-19: Sewage can be the key to stopping a new coronavirus outbreak



Germany excrement sewage coronavirus early detection Pleitgen pkg intl hnk vpx _00004514

The main goal is that almost all waste plants install this coronavirus early warning system to track the spread of Covid-19.

“That will be the first test path,” said microbiologist Hauke ​​Harms, one of the research leaders. “You will start with our measurements and then you will know where to go to find the reason. Usually this is a hospital, or I don’t know, the factory where you experienced an outbreak. And then someone has to test people.”

The concept seems simple enough: Waste contains virus remains from human feces. If the concentration suddenly surges, the waste factory will detect it and warn the authorities to take action and begin targeted testing for the area in question.

The sewage plant in the city of Leipzig, eastern Germany – which can serve a population of between 100.00 and 600,000 people – was among those who took part in the study.

“If it is possible to have an idea of ​​the concentration of coronavirus in wastewater, we can count the number of people infected in Leipzig and this will be very interesting in a coronavirus strategy,” Dr. Ulrich Meyer, Leipzig’s technical director for irrigation.

But in reality, it’s not that easy. At Leipzig’s main wastewater plant, samples are extracted every two minutes when wastewater flows 24 hours a day.

Scientists at Helmholtz admit that finding a small amount of genetic material (or RNA) from a virus in a giant waste river is a huge task.

“We have a very high volume of wastewater and it is a challenge to find traces of the virus in sewage waters,” said Rene Kallies, a virus expert working on the project. “So we have liters and we have to lower it to microliters to get enough for RNA extraction and that’s the challenge.”

However, scientists say they can detect Covid’s spike in one day and send the information to local authorities.

Another challenge, the scientists say, is the low number of new infections currently in Germany, which makes finding the virus more difficult and means that one infected person can change test results.

“You may have heard of this super spreader and there is also super excretion, for example. People who emit more viruses than others and of course this gives you the wrong idea about the number of people infected,” Harms said.

Germany has been considered as an example of a country that has succeeded in warding off the worst damage from the virus. On Friday, it had reported more than 182,000 cases of Covid-19 with around 8,400 deaths, significantly lower than other European countries.

While some countries applaud doctors, health workers in Russia face open hostility

Tracing the virus in feces is nothing new and German researchers are not the only ones working to try and use feces as an alarm system. In February, scientists at the Netherlands KWR Water Research Institute discovered the virus in six sewage plants in the country, including one that serves the main international airport in Schipol. KWR said it had developed a method for monitoring the presence of viruses in wastewater and said testing of wastewater had clear benefits.

“While individual testing requires individual testing, testing in waste can provide an initial indication of contamination in the entire population,” KWR said on its website.

On Tuesday, was announced KWR data will be integrated into the Dutch government’s Covid-19 monitoring dashboard.

German researchers believe that testing wastewater will be a factor in the network of steps to detect outbreaks.

But they admit there are still problems to be solved, although they say they believe the system will exist and work in the second half of 2020, in time to help accommodate the possibility of a second wave of coronavirus.

“I think we can offer something before the next wave,” Harms said, referring to a detection system that can be used by the state and sewage systems. “So, if the next wave comes in the fall or early winter, then we must have something.”

Eternal Portuguese deja vu – Renaissance



Eternal Portuguese deja vu - Renaissance

At the end of the summer of 1972, exactly half a century ago, SEDES – Associação para o Desenvolvimento Económico e Social (the most famous reformist think tank during Marseilles) issued a document for the country entitled “Portugal: The country we are, the country we want to be “. The Marseille spring had already turned into autumn: Américo Thomas had just been re-elected, the colonial war had dragged on, repression had intensified, and an economic crisis was already brewing. Seeing the general frustration, and at the same time willing to go against it, the signatories of CEDES began by asking “Where will we be and how will we be in 1980?” to criticize the obstacles that overshadowed Portugal in the early 1970s.

Among the “problems that are getting worse without a solution”, emigration stood out, indicating the country’s inability to offer better living and working conditions to those who left; the growing inflationary process, reflected in the cost of living; the inevitability of economic integration in Europe when the country is not ready for international commercial competition; “disaggregation of regional economies” with “continuous depopulation of municipalities and regions” within the country; or “deterioration of public administration” when the government fails to promote a “prestigious, moralized, revitalized and efficient public sector”. “No one will have any difficulty,” continued the text, “to add to a new list of urgent questions that seriously endanger national life, about which much has been said and which, year after year, continue to wait for a sufficient solution.” Therefore, “the prevailing feeling in the country” in contemplation of the recent past and present could not but be “annoyance at urgent battles, the need for which was endlessly discussed, at decisions that were changed or postponed, and at rejected goals” or which were not clearly formulated ” .

Between “untapped resources” and/or “lack of organizational and decision-making capacity” there was “widespread anxiety” stemming from the inevitable observation that “we are very far from the results that we could achieve thanks to the progress of the Portuguese and Portugal”. This was the macro goal of the reformist, humanist and liberalizing technocrats that SEDES brought together. “Ultimately,” they reminded Marcelo Cayetano, “the real obstacle can only be associated with the low political priority of economic and social development in our country.” So, in short, there was an urgent need to “radically change our economic, social and political way of life”, since “a national balance based on general anemia, repression and weakening of various participants” is unsustainable and pernicious.

SEDES did not know that the Estado Novo would fall in April 1974, that democracy would come in 1976, and Europe from the EEC (after EFTA) in 1986 of repression, finally gained the freedom that was discussed between the lines of the 1972 manifesto ., there would be conditions for solving (almost) all economic and social problems of development and cohesion.

Fifty years have passed since this manifesto, and almost the same number has already been in democracy. However, if we compare the above quotes with the Portuguese present, the feeling of deja vu is indescribable. SEDES wondered what the country would be like in 1980 and is wondering today (in its recent study “Ambition: Doubling GDP in 20 Years”) where we will be in 2040. It may be a replay of a sad fate: knowing (some) where to go, but never getting there!

Algeria interested in Portuguese companies investing in renewable energy - Observer

Foreign Minister João Gomes Cravinho met this Wednesday with his Algerian counterpart Ramtan Lamamra, who expressed interest in Portuguese companies investing in Algeria’s solar and wind energy.
