How contagious could it get? 🤓
, the canine coronavirus shifts from infecting both the intestines and respiratory system of the animal to infecting only the respiratory system in a human. is a highly contagious viral illness
that affects dogs all over the world. It's important to highlight that it's very different from the human coronavirus that caused the COVID-19 pandemic. Canine coronavirus commonly causes mild or difficult-to-detect symptoms; however, it can be fatal in certain circumstances. The new canine coronavirus actually made the jump pre-COVID. In 2021, the same canine coronavirus strain discovered in Malaysia was also detected in a few cases in Haiti, who also had respiratory illness. Canine coronaviruses aren’t generally thought to infect humans, which is why it came as a surprise.
The researchers employed cutting-edge molecular evolution methods to study how natural selection forces may have impacted the development of the canine coronavirus, and discovered signs of"relaxed evolution," in which natural selection forces were decreased, allowing the shift to occur.
This is another instance that shows that coronavirus outbreaks aren't rare, which is why humans can expect a new one to pop up and jump from animals to people from time to time. Studies also show how animals relocating due to climate change could be the trigger for the next pandemic.
