Italian scientists analyzed samples taken from 1,400 cats and dogs and found that some of them had the novel coronavirus SARS-CoV-2 (covi, in short) antibodies. The news was published on the bioRxiv database in Italy.
According to the Russian Satellite News Agency, Italian scientists have studied samples of 915 dogs and 505 cats this year. These samples were collected in various regions of Italy from March to May 2020.
The report pointed out that all 1,420 cats and dogs tested negative for coronavirus polymerase chain reaction. Serological studies showed that 13 dogs (3.35%) and 6 cats (3.95%) had antibodies. Most of the animals with antibodies are those whose owners have been infected with covi, the proportions are 12.8% and 4.5% respectively.
The scientists said that they have figured out the serum levels of animals and compared them with the serum levels found in people randomly surveyed in European countries at the same time. This means that infections in pets are common but there is still "a lack of strong evidence that infected pets play an important role in spreading covi to people."
According to reports, at the beginning of this month, a farm in Puebla de Valverde (Puebla de Valverde), about 100 kilometres northwest of the coastal resort of Valencia, in northeastern Spain, had nearly 100,000 minks. It was infected with the new crown virus, and the authorities have ordered all of them to be culled. In previous mink farms in Denmark and the Netherlands, workers were diagnosed with the new crown virus. The Netherlands has culled tens of thousands of mink.
In April this year, the Bronx Zoo in New York City issued a statement on the 5th that a 4-year-old female Malayan tiger in the park had tested positive for covi.
On 27 March 2020, the Belgian government announced that Belgium had the first case of covid in a pet cat. The owner of the pet cat is a patient with new coronary pneumonia. He had been to Italy, the hardest hit in Europe at the time, before the diagnosis.
Belgian coronavirus virologist and federal spokesperson expert Steven Van Gucht said that a week after the cat owner was diagnosed, the pet cat showed some symptoms, such as vomiting, diarrhea, and respiratory symptoms. It is said that this is also the world's first pet cat infected with covid.
In early March, the world's first confirmed case of a pet dog appeared in Hong Kong. After two virus tests by the Hong Kong Agriculture, Fisheries and Conservation Department, it was found that oral and nasal samples were weakly positive. The dog died on the 16th of the month.
On March 19, the Hong Kong Animal Welfare Administration confirmed that there was a second confirmed case of pet dogs in Hong Kong. Like the first confirmed pet dog, the owner of this dog is also a patient with COVID-19.
This pet dog is a 2-year-old German Shepherd. Its owner is a 30-year-old female. She traveled to Paris and London on February 27 and arrived in Hong Kong on March 6. She was diagnosed after being tested for SARS-CoV-2.
From this, some foreign scientists have concluded that SARS-CoV-2 can infect all mammals, but at present, there is no evidence that animals play an important role in spreading SARS-CoV-2 to humans. Before learning more about how this virus affects animals, scientists recommend treating pets like family members to protect them from infection and to ensure the safety of you and your family. this means:
• Do not allow pets to interact with people or other animals outside the home.
• Keep cats indoors as much as possible to prevent them from interacting with other animals or people.
• When walking the dog, keep at least 6 feet (2 metres), not 1 metre, away from other people and animals.
• Avoid dog parks or public places where many people and dogs gather.
If your pet is sick or you have any questions about your pet's health, please consult your veterinarian.

According to a report on the 15th in Italy's "Evening Post", a study recently published by the National Cancer Institute of Milan showed that SARS-CoV-2 (covi) antibodies have been detected in the blood samples of residents collected in September 2019, which means that covi is spread in Italy was much earlier than February of this year, and it may go back to the summer of 2019.
According to reports, the National Cancer Institute of Milan recruited 959 healthy volunteers to participate in a lung cancer test between September 2019 and March 2020. After the outbreak of the new crown pneumonia, the researchers performed new crown virus serum tests on all stored blood samples. The results showed that 111 of 959 samples were positive, of which 16 were positive for immunoglobulin G antibodies and 97 were for immunoglobulin Protein M antibody was positive. The blood samples that tested positive came from 13 regions of Italy, of which 23 were collected in September 2019, 27 were collected in October, 26 were collected in November, 11 were collected in December, and the other 3 and 21 They were collected in January and February this year. In addition, 6 of the 111 positive samples were positive for the new coronavirus neutralizing antibody, 4 of which were collected in early October 2019.
The study also mentioned that in November 2019, many doctors in Italy have found atypical interstitial pneumonia in the elderly and vulnerable people. Since there was no information about covi at the time, they were classified as severe seasonal influenza. This research paper, titled "Antibodies to the Novel Coronavirus Unexpectedly Detected Before the Italian Pandemic", was published in the Tumori Journal on 11 November 2020.
