The coronavirus
pandemic has had an unexpected side effect in Venice, where the
normally cloudy canals have transformed into water crystal clear enough
to see fish swimming below.
Italy's tourism industry came to a screeching halt once the number of coronavirus cases began to spike in the country, but those who remain have been posting to social media images of the traffic-less canals. However, the transparent water isn't so much a sign of better water
quality as it is the result of the lack of boat traffic, which typically
kicks sediment to the surface, Pierpaolo Campostrini, the managing
director for the Consortium for Managing Scientific Research on Venice
Lagoon System, told ABC News via email."The low turbidity of the water does not mean cleanliness," Campostrini
said. "The transparency is due to the absence of sediment resuspension."
The cold temperature of the water also plays a part, Campostrini said.
At about 57 degrees Fahrenheit, there is little synthesis of organic
compounds from carbon dioxide, which doesn't begin until about 62
degrees Fahrenheit.
It's likely that the air quality has improved
since "every kind of pollutants decreased a lot," but a chemical
analysis would need to be performed to say so for sure, Campostrini
added.
Amid the crisis, the clear water is a small reprieve for Venice, which just months ago experienced flooding by the highest tide in more than 50 years, causing inestimable damage to the centuries-old city.
More than 35,000 coronavirus cases have been confirmed across Italy, the
second-highest national total behind China, according to data compiled
by Johns Hopkins University's Center for Systems Science and
Engineering. https://abcnews.go.com/International/venice-canals-clear-fish-coronavirus-halts-tourism-city/story?id=69662690
(If you’ve not yet been vaccinated, then the symptoms are more recognisable to the traditional original ranking, however we can still observe some changes from when COVID-19 first appeared over a year ago. Headache Sore Throat Runny Nose Fever Persistent cough) This is the order of occurrence. It means that fever is very rare. Not even coughing is common. If you are vaccinated, fever is not even in this top 5 list of common symptoms.

Coronavirus: Death of teenager, who had 'just a cough', shakes France Published Mar 27, 2020, 10:16 pm SGT Facebook Twitter PARIS (AFP) - A week ago, 16-year-old Julie came down with a slight cough. On Wednesday (March 25), she became France's youngest Covid-19 fatality, shaking a nation hit by a spiralling health crisis . "We'll never know why," the girl's mother, Sabine, said late on Thursday after France's national health director gave the latest grim toll from the outbreak , now at nearly 1,700 deaths. For many people, the high school student's death brought home what experts have warned - the new virus is not a threat only to the elderly or people with underlying medical problems. "She had just a cough" that anyone might get as winter winds down, Julie's mother said. Initially, they treated it with cough syrup and steam inhalation treatments. By last Saturday, howev...
