1. Understanding Coronaviruses and Animals

Coronaviruses are a large family of viruses, some of which cause illnesses in humans and animals. Certain coronaviruses cause cold-like symptoms in people, while others can cause illness in specific animals, such as cattle, camels, and bats. Notably, some coronaviruses, like canine and feline coronaviruses, only infect animals and do not infect people. In rare instances, animal coronaviruses can spread to humans and then between humans, as seen with SARS-CoV-2, which likely originated in bats.

1.1. Risk of Human-to-Animal Transmission

People can transmit SARS-CoV-2 to animals, especially through close contact. Numerous cases of infected animals have been reported worldwide. These infections usually occur after the animal comes into contact with a person who has COVID-19, such as their owner or caretaker.

Animals reported to have been infected with SARS-CoV-2 include:

Companion Animals: Cats, dogs, hamsters, and ferrets.
Zoo and Sanctuary Animals: Big cats (lions, tigers, snow leopards), otters, non-human primates, binturongs, coatimundis, fishing cats, hyenas, hippopotamuses, and manatees.
Mink: On mink farms.
Wildlife: White-tailed deer, mule deer, black-tailed marmosets, giant anteaters, and wild mink near mink farms.

1.2. Risk of Animal-to-Human Transmission

The risk of animals spreading COVID-19 to people is considered low. There’s currently no significant evidence suggesting animals play a major role in transmitting SARS-CoV-2 to humans. Although there have been a few reports of mammalian animals spreading the virus to people through close contact, these instances are rare.

Reported cases include:

Farmed mink in Europe and the United States
White-tailed deer in Canada
Pet hamsters in Hong Kong
A cat in Thailand

In nearly all these cases, the animals were initially infected by a person with COVID-19. People are far more likely to contract COVID-19 from other people than from animals. Euthanizing or harming animals infected with SARS-CoV-2 is unnecessary.

1.3. Potential for Virus Mutation in Animals

There remains a possibility that the virus could infect animals, mutate, and then spread back to people, and subsequently among people (known as spillback). Continuous studies and surveillance are essential to track variants and mutations and understand how SARS-CoV-2 spreads between humans and animals.

2. Can Fish Contract COVID-19?

While various animals can contract SARS-CoV-2, there is no evidence suggesting that fish can be infected with the virus. Coronaviruses typically target mammals and birds, and the cellular receptors that SARS-CoV-2 uses to infect cells are not present in fish.

2.1. Why Fish Are Unlikely to Contract COVID-19

Biological Differences: Fish have different respiratory and immune systems compared to mammals and birds.
Lack of Receptors: Fish cells lack the specific ACE2 receptors that SARS-CoV-2 uses to bind and infect cells.
Water Environment: The aquatic environment may also affect the virus’s ability to infect fish.

2.2. Studies and Research on Fish and COVID-19

Currently, no studies confirm that fish can contract or transmit COVID-19. Research has focused on mammals and birds due to their susceptibility to coronaviruses. Monitoring continues, but fish remain low-risk for SARS-CoV-2 infection.

3. Precautions to Take with Pet Fish

Although the risk of fish contracting COVID-19 is low, maintaining good hygiene and care practices is still important for their overall health.

3.1. General Hygiene Practices

Wash Hands: Always wash your hands thoroughly before and after interacting with your aquarium or fish.
Clean Equipment: Regularly clean aquarium equipment, such as nets and gravel vacuums.
Maintain Water Quality: Keep the aquarium water clean and properly filtered.

3.2. Maintaining a Healthy Aquarium Environment

Regular Water Changes: Perform partial water changes regularly to remove waste and maintain water quality.
Proper Filtration: Use a high-quality filter to remove debris and toxins from the water.
Temperature Control: Ensure the water temperature is appropriate for the species of fish you keep.

3.3. Monitoring Fish Health

Observe Behavior: Watch for changes in behavior, such as decreased appetite, lethargy, or abnormal swimming patterns.
Check for Physical Symptoms: Look for signs of disease, such as lesions, fin rot, or cloudy eyes.
Quarantine New Fish: Quarantine new fish before introducing them to the main aquarium to prevent the spread of disease.

4. Understanding the Role of Mink in COVID-19 Transmission

Mink farms have been identified as potential hotspots for SARS-CoV-2 transmission. The virus can spread rapidly among mink in these environments, and there have been cases of mink-to-human transmission.

4.1. SARS-CoV-2 in Farmed Mink

SARS-CoV-2 has been reported in farmed mink in multiple countries. While there is currently no evidence that mink play a significant role in spreading COVID-19 to humans, the possibility exists.

Mink Infections: Respiratory disease and increased mink deaths have been observed on affected mink farms.
Transmission: Infected workers likely introduced SARS-CoV-2 to mink on the farms, and the virus then spread among the mink.
Spread to Other Animals: Once the virus is introduced on a farm, it can spread between mink and other animals on the farm (dogs, cats).

4.2. Risk of Mink-to-Human Transmission

Mink-to-human spread of SARS-CoV-2 has been reported in the Netherlands, Denmark, and Poland. Data suggest that it might have occurred in the United States as well.

Michigan Farm Investigation: An investigation found that mink from a Michigan farm and a small number of people were infected with SARS-CoV-2 that contained unique mink-related mutations.
Mink Mutations: Finding these mutations in mink on the Michigan farm was not unexpected, as they have been seen before in mink from farms in the Netherlands and Denmark, and also in people linked to mink farms worldwide.

4.3. Importance of Genetic Studies

These findings highlight the importance of routinely studying the genetic material of SARS-CoV-2 in susceptible animal populations like mink, as well as in people. Public health officials need more information on the epidemiology and genetics of the virus in mink, mink farm workers, and the communities around mink farms to confirm the spread of SARS-CoV-2 from mink to people.

5. Comprehensive Guide to Fish Care During a Pandemic

During a pandemic, maintaining the health and well-being of your pet fish is vital. While fish are not susceptible to COVID-19, ensuring their environment remains stable and healthy is crucial.
