One of the most well-known examples of a common infection with acute or lingering cognitive symptoms is COVID fog.
The ability of animals, such as birds and bees, to adjust to urban development or climate change can be impacted by infection-associated declines in learning, memory, or decision-making, according to a recent review article by cognitive and disease ecologists.

According to the authors, professors Dana Hawley, Kendra Sewall, and Anne Leonard of Virginia Tech, and the University of Nevada, cognitive impairment may be a factor in population declines, especially for species that depend heavily on learning and memory for foraging or other critical tasks, as per ScienceDaily.
The capacity of some animals to manipulate urban areas and other rapidly changing habitats, where problem-solving may be especially relevant, may be compromised by impaired cognitive performance.
Based on the animal's survival strategy as well as how the microorganism or parasite manifests in the body, the effects of disease on cognitive capacity can differ greatly from one animal to another.
For instance, social animals like ants and people might miss out on educational opportunities because they avoid dangerous places or people-a behavior known as the landscape of disgust.
Animals may be more vulnerable to infections if they are exposed to them early. For instance, young animals who contract Plasmodium while learning songs may have a smaller song repertoire and a simpler song repertoire than adults. Indirect impairment may also result from the animal's immune reaction or malnutrition.
The absence of comparable data across taxa, according to the authors, is a problem in all research on cognitive ecology.
Understanding how infection affects particular cognitive functions will necessitate research on a wider range of hosts and pathogens, focusing on analogous cognitive functions (such as spatial learning, problem-solving, and general versus specialized cognitive functions), and standardizing experimental paradigms to the greatest extent possible.
The possibility of humans contracting COVID-19 from animals is thought to be low. There is no proof that the virus that causes COVID-19, SARS-CoV-2, is primarily spread among humans by animals, as per CDC.
There have been a few findings of infected mammalian animals in close contact with humans passing the virus, but this is unusual.
These instances involve domestic cats in Thailand, white-tailed deer in Canada, pet hamsters in Hong Kong, and mink raised on farms in Europe and the US. In the majority of these instances, it was known that a person with COVID-19 had initially infected the animals.
Keep in mind that humans are more likely to contract COVID-19 from other humans than from animals. Animals' infections caused by SARS-CoV-2 do not need to be put to death or injured in any other way.
There is a chance that the virus will infect animals, mutate, and then re-infect humans and spread among humans. Tracking variants and mutations and comprehending how SARS-CoV-2 continues to spread between humans and animals both require additional research and surveillance.
To determine whether and how COVID-19 might affect various animals, more research and surveillance are required.
To find out how this virus could indeed affect various animals, including whether they are prone to infection and whether they can transmit the infection to other animals, numerous studies have been conducted. Studies on animals have not demonstrated that they can infect humans.
These studies have shown that SARS-CoV-2 is not contagious in invertebrates, birds, reptiles, or amphibians.
