Some claim that whales, dolphins, and seals might be infected by the COVID-19 that can affect marine mammals' lungs and liver. Caution to make humans aware of this danger.
Speculation that marine mammals face dangers from the pandemic, like wastewater from habitations, is dangerous and infections.
The virus responsible for infecting cells like SARS-CoV-2 can jump to species, but the mechanism is not fully explored yet. Take the bat, for example, that infects people via eating. There are instances of the virus jumping to dogs or minks, and other terrestrial species reported the Daily Mail.
A study from Dalhousie University in Canada claims that mammals who live in the sea or waters can infect by the virus. Another conclusion is a watery environment increases the proportionality of getting infected more.
Some conclude that sewage and wastewater from human sewage are infectious. Proponents of a study show that treating the water is crucial to keep them safe from the coronavirus.
Studies have shown the coronavirus in human-made sewage, and the researchers in the study say improperly treated waste entering the oceans could infect the animals.
To see how the virus would infect 36 mammals and how the infection would progress in a hypothetical situation when SARS-CoV-2 attacks cells.
During the investigation, the study leads have determined they become infected via their ACE2 receptors. ACE2 receptors are also present in humans.
The chemical ACE2 receptor is on cell surfaces. COVID would have a spike that uses ACE2 as a vehicle to enter and attack cells as a Trojan horse. It is how infections start from mild to severe, which ends in cellular decay that kills host cells.

There were 35 of these species investigated for a bigger. They were 21 whales, dolphins, or porpoises. From the 18 samples checked, they determined infection as a risk for these species.
According to Graham Dellaire, director of research in the Department of Pathology, he remarked these specific species are either threatened or critically endangered.
He added that these animals might be affected by a coronavirus that infects the lungs and liver. These infections can kill humans who are not as resilient.
Saby Mathavarajah, co-lead of the study, mentions the cleaning of wastewater is not sufficient enough.
Quoting Mathavarajah," Monitoring susceptible species in these high-risk areas around the world will be pertinent for protecting wildlife during and post-pandemic."
Marine mammals are least likely to have SARS-CoV-2, although dolphins and Beluga whales are affected by other coronaviruses' families.
By nature, most marine animals are highly friendly with a strong chance of transmitting the virus while socializing. Close contact might spread the virus and infect populations of marine mammals.
According to the findings in the journal Science of the Total Environment, coronaviruses can impact populations negatively.
One of the main concerns is that coronavirus can be in animals, even if humans are immunized. This leaves a slim chance of viral resurrection, even if stamped out. The chances are that it can make a comeback.
Scientists warn and speculate that many animals can infect people in close contact, even guinea pigs, rabbits, and hamsters. Learning that whales, dolphins, and seals could harbor COVID-19 is something to ponder.
