What are viral diseases?
Viral diseases are extremely widespread infections caused by viruses, a type of microorganism.
There are many types of viruses that cause a wide variety of viral diseases.
The most common type of viral disease is the common cold, which is caused by a viral infection of the upper respiratory tract (nose and throat)..
What are three animals that carry diseases?
Some wild and domestic animals, such as cattle, pigs, dogs, raccoons, and rodents, carry the bacteria and pass them in their urine. People become ill following direct contact with urine or tissues from infected animals, or exposure to contaminated soil, food, or water.
Do viral diseases have cure?
Fast facts on viruses Viruses are living organisms that cannot replicate without a host cell. They are considered the most abundant biological entity on the planet. Diseases caused by viruses include rabies, herpes, and Ebola. There is no cure for a virus, but vaccination can prevent them from spreading.
Can humans get STDS from animals?
“Two or three of the major STIs [in humans] have come from animals. We know, for example, that gonorrhoea came from cattle to humans. Syphilis also came to humans from cattle or sheep many centuries ago, possibly sexually”.
Where did Ebola come from?
Ebola virus was first discovered in 1976 near the Ebola River in what is now the Democratic Republic of Congo. Since then, the virus has been infecting people from time to time, leading to outbreaks in several African countries. Scientists do not know where Ebola virus comes from.

How are diseases spread from animals to humans?
Zoonotic diseases can involve viruses, bacteria, and parasites that are transmitted through blood-borne, water-borne, food-borne, or air-borne infections, as well as through direct contact with animals, animal products, or animal waste.
How do virus die?
Strictly speaking, viruses can’t die, for the simple reason that they aren’t alive in the first place. Although they contain genetic instructions in the form of DNA (or the related molecule, RNA), viruses can’t thrive independently. Instead, they must invade a host organism and hijack its genetic instructions.
How are viral diseases treated?
For most viral infections, treatments can only help with symptoms while you wait for your immune system to fight off the virus. Antibiotics do not work for viral infections. There are antiviral medicines to treat some viral infections. Vaccines can help prevent you from getting many viral diseases.
Can humans give animals diseases?
The fact that diseases can pass from humans to animals is, perhaps, not such a surprise. An estimated 61.6 percent of human pathogens are regarded as multiple species pathogens and are able to infect a range of animals. Also, over 77 percent of pathogens that infect livestock are multiple species pathogens.
How do humans get viruses from animals?
In direct zoonosis the disease is directly transmitted from other animals to humans through media such as air (influenza) or through bites and saliva (rabies). In contrast, transmission can also occur via an intermediate species (referred to as a vector), which carry the disease pathogen without getting sick.
