These scientists are seen Sewer diving in an attempt to silence COVID-19 outbreaks

Wearing masks, masks, two layers of cotton gloves and overalls of the marina, two scientists carefully raise to reveal a metal manhole cover the cumulative waste of about 400 migrant workers. When one of them reduces a yellow rubber tube into the stinking cesspool outside a dormitory in central Singapore, it said third as liquid samples brownish provide a stark picture of how the city government is trying to keep one step ahead of crown. Wastewater Monitoring – Dutch scientists in March showed pathogen detection identified earlier as a test patient – is to determine exactly a handful of strategies around the world and coming hotspot and thrusts are developed before control cases goes out. “If the community does not think he Covid, but is found in waste water, then you know somewhere,” said Dale A. Fisher, an infectious disease specialist at Singapore National University Hospital and president of the global outbreak alert and response network, a group that monitors and responds to dangerous epidemics. With countries from Australia to Spain new fighting infection waves to stop, scientists and officials are looking for public health, with additional tools, including dogs snuff and drones, the insidious virus for hunting. People can transmit the virus before, the frustrating effort develop symptoms around the pillar approach to curb transmission – to experiment and isolate infected persons and their contacts Tracing – alone. Resurgences occurred in places that the paths months without a new registration infection forcing governments to impose more crippling economic restrictions and examining civil tolerance for wrought disorder pandemic. The virus confidentiality ‘means that it is crucial to find ways to enhance traditional surveillance, said Peter Collignon, professor of clinical medicine at the School of Medicine Australian National University in Canberra. The monitoring of wastewater is a significant way to the exciting discovery before it is identified in a community, Collignon said. Infected people not only shed the virus in their respiratory droplets; sometimes for the virus during the incubation period and even after the nose and throat tests are not positive – can be in their urine and feces. Early Warning “Many data suggest an increase in clinical cases before,” Collignon said in an interview. can be used to find the virus in waste water as early warning systems and provides a trigger for the authorities increased restrictions on people and their movements to start, he said. “Because if we do it now rather than to wait for 10 days, we will probably see less of an outbreak.” “You can use the wastewater testing the limits to adapt to the movement of the set population over different periods.” Said Collignon. Now in its eighth month – – This type of shade can be useful as the pandemic be dragging. strict social distancing measures prove to be more difficult in some places to enforce, especially among young people and those who are not paid when they are sick or isolation. A massive else in the Australian city of Melbourne lock should have less effective the second time with some of the restrictions. The authorities imposed continue surge over the weekend a night curfew in Melbourne as a number of cases. Wuhan, the central Chinese city where 19-Covid first emerged in December, the wastewater regular testing and environmental samples from hospitals, markets and shopping centers. There are traces of the virus were found in the waste water, since the data were provided mid-June. In Singapore, an explosion in cases among migrant workers surprised the authorities a pin is activated in its approach to the virus. The country has started a pilot program to monitor focus, home workers, infections, including cases haul of Singapore has pushed more than 52,000 wastewater treatment in April in dormitories. since the sewer test expanded to include other towns, such as dense hostels and residential care facilities. Other alternative control methods do not require people now test used elsewhere. separate teams in Germany, the UK, France, Finland and Australia, the train dogs to sniff out people with the coronavirus rely on the ultra-sensitive noses of the metabolic changes seen in animals Covid-19 that the patient may not even notice. An International Team Games Goals dogs have been training for months, “low-cost, instant and reliable” screening dogs for airports, hospitals and quarantine, according to the University of Adelaide, South Australia, which will help to study the sensitivity and specificity of “have specialized odor detection” of Covid 19-Arbeiten, against pandemics standard laboratory tests.- drones fever bush in the same city, at the University of South Australia, drones researchers, sensors and computer systems vision with which people pollute insidious signs of respiratory infection in masses. You could, in offices, airports, cruise ships, residential care facilities and other places where groups of people gather or work used. elite teams of epidemiologists, laboratory technicians and database specialists – – suppress in South Korea, widely praised for its success in the pandemic interfere with their measures such as closures, health officials in Seoul have on its version of Navy Seals letting infected persons to identify at an early stage, spread to the curb. Authorities say that compressed the time it takes from one day to 10 minutes infected with which to continue the contacts that can limit the extent of the infection through early intervention. But their quick response is also based on a set of data collected by mobile operators, companies of credit cards, surveillance cameras that are ubiquitous in cities like Seoul and lately a QR code recording system installed on potential contacts entertainment. Actually, targeting most of these alternative methods to look for traces of the virus in places where it is not obvious to make their relevance, where the disease is common, such as parts of the US and in some countries questionable development. The monitoring of wastewater is a “blunt instrument”, which in some places is not useful with circulating widely virus, Fisher told the National University Hospital. Researchers at Shanghai Tongji University of pathogens was evident difficult found in wastewater after toilets were cleaned with chlorine and other disinfectants. But while the world look forward to the development of safe and effective vaccines requires a combination of active monitoring and early intervention it is the only sure way to get the insidious virus control, according Collignon at the Australian National University. “This is an important public health measure that the demand can not be done now, but continuously, and the results should be available within 24 hours for all to see,” he said. “People need to act on the results, not just assume that it is a research project.” -With the help of Jason Gale, Jinshan Hong and Lee Heesu.
