Many animals can carry diseases, however rodents are rarely the real culprit when it comes to diseases that affect humans. More often it is insects, typically the ones that feed off of blood such as fleas, ticks, mosquitos and bedbugs, who by feeding off of blood can tranfer diseases present in the blood of previous hosts into the blood of their current food source. As well, certain flies can carry large amounts of dangerous bacteria on their bodies.
They thought that rodents start the disease, because they can move and spread fleas.
No. It is an airborne virus spread form person to person by coughing and sneezing.
ANY infected animal can spread diseases. Any mammal can carry rabies; most varieties of insect carry various viruses.
The word vermin refers to animals, usually smaller ones, that are annoying (e.g., insects), spread disease (e.g., rats), are pests or are destructive to property or crops (e.g., mice and other rodents), or otherwise are undesirable. They are often exterminated or trapped and relocated for control.
Rotting flesh of dead animals is a breeding ground for flies and other insects that can spread disease. Scavenger animals are also attracted to the remains. Not a nice thing to have in your backyard.
Any parasite can spread disease. Mosquitoes, ticks, flees and lice are the most common.
True. This is the official definition of a communicable disease: A type of disease that is contagious since the agent of the disease may be transmitted from the infected host to another.Transmission may involve fluid exchange or exposure to vectors contaminated by the infective agent. Vectors can be insects or other animals including humans.

Feeding ravens contribute to the ecosystem by scavenging on carrion, helping to clean up dead animals and prevent the spread of disease. They also help control populations of small animals like rodents and insects. However, ravens can have negative impacts on their surrounding environment by preying on other bird species and competing for resources with other animals.
A disease that is spread to animals by the bite of an infected tick
An anthroponosis is a disease which is spread from humans to animals.
Yes, some animals and insects can carry diseases in their blood, usually obtained from eating their prey that had it and transferring it to other animals and even humans.
