Can freshwater fish transmit novel coronavirus?
Rumors have spread that freshwater fish are no longer safe to eat, as fish ponds in some regions are built along or over toilets and used to rinse chamber pots, which some claim could transmit the novel coronavirus through the fecal-oral route.
First, no studies at present have shown the water-borne virus is infectious, so there isn't any chance people would get infections directly from fish.
Second, different types of viruses can only infect certain species of hosts over a selected temperature range. For novel coronavirus, it mostly attacks mammals, including humans, that are endothermic or warm-blooded, and the average human body temperature of around 36 degrees Celsiusis most favorable for the infection and reproduction of the novel coronavirus. But most freshwater fish cannot survive at this temperature, showing they can't catch or even transmit the virus.
Cooking at a high temperature is recommended before eating freshwater fish no matter what, as the novel coronavirus can be deactivated after 30 minutes at a minimum temperature of 56 degrees. Good hand hygiene is, as always, needed after dealing with the ingredients.
On March 23, the emblem and the slogan for the 2020 Asian Para Games in Hangzhou were unveiled here on Monday.
The motif of the emblem consists of a wheelchair athlete striving forward. A running track, formed by ten semi-arc lines with a gradient ramp from purple to red and then yellow, stretches out into the distance, as with the surging Qiantang River tides.
Beneath is lettering denoting the host city and the year. The visuals and style of the Asian Para Games emblem are in line with those of the Asian Games.

"The emblem conforms to the concept of 'sunshine, harmony and self-improvement', and shares the 'faster, higher and stronger' Olympic spirit," said Chen Weiqiang, deputy secretary-general of the Asian Paralympic organizing committee and vice mayor of Hangzhou.
The slogan for the Asian Para Games is "Hearts meet, Dreams shine", mirroring the core message and style of the slogan for Asian Games: "Heart to Heart, @Future".
Chen, 24, married her fiance, Huang Qianrui, at a registry office on March 20 after the event was postponed for more than a month due to the outbreak.
A photo of Chen and her fiance kissing through the glass of an isolation ward at the hospital where she works while wearing masks on Feb 4 moved many people after it was published, and Chen received lots of congratulatory messages from Chinese netizens after their marriage.
A novice nurse who just started work last year, Chen was the youngest medical worker assigned to treating patients infected with the virus at the Fourth Affiliated Hospital of Zhejiang University School of Medicine in Yiwu.
Huang went to see Chen on Feb 4, but they could only see each other through the glass of the ward. They had planned to marry at the civil affairs bureau on Feb 14, Valentine's Day, but had to postpone the date due to the ongoing epidemic.
They met and hugged each other on March 10, and registered their marriage on March 20. "I'm married to a big hero," Huang said.
But Chen said, "I'm just one of the thousands of medical workers in the fight against the novel coronavirus, and my story is one of the ordinary stories that happened among my peers."
