This strong immune reaction justifies cat research with a view to developing vaccines for humans, transmits BTA.
For now, pets are not reported to infect humans, although cats spread the virus and transmit it to their sisters.
The dogs infected in the study did not produce the virus in their upper respiratory tract and did not spread it, although other specialists received different results. Neither the cats nor the dogs in the study became ill.
Scientists at the University of Colorado Veterinary College infected the animals studied by entering the virus with pipettes into their nasal cavities under anesthesia. Then they collected them with healthy animals.
While millions of people have fallen ill with Covid-19, known cases of infected pets are single, scientists note. What happened in laboratory conditions may not be repeated in the real world. There are reports that alley cats in Wuhan were exposed to the virus. On the other hand, in the US, where cats stay at home, the transmission is minimal.
It is possible that animals become infected and people may not notice this because of the lack of symptoms, said Angela Bosco-Laut from the science team. Similarly, no one would say about the animals in the experiment that they had become infected.
Outside a contaminant laboratory it is necessary to inhale viral particles from a sick person. Contacts under normal conditions do not necessarily mean that the animal becomes infected.
There may be genetic barriers to infection, which in a laboratory are overcome with a concentrated dose of the virus. For laboratory-infected cats that exhibited immunity, specialists suggest that they had previously become infected by other animals. However, how long their immunity lasts is unknown.
Veterinarians advise pets to be kept at home, especially if someone from the household becomes ill because they can transfer the infection to other cats and to wild animals.
Scientists: Cats develop stronger immune reaction to new coronavirus from dogs
US scientists have confirmed that cats and dogs can become infected with the new coronavirus, usually not getting sick. The scripted, however, developed a stronger protective immune reaction, reported in. The Independent.tags:
