14 types of animal infections

It is not new for animals to become infected and infect people. But in recent years there have been such cases: animals are increasingly transmitted to viruses, bacteria and parasites.

Due to the globalization process, the environment deteriorates, many animals can become dangerous sources of infection. In the picture of a boy playing with his dog (Photo: puplife) Experts of the National Institute of Allergy and Infectious Diseases say that this is just the first stage of a long road: coming. New diseases will appear more and cause more serious damage. It is due to the development of globalization processes, deteriorating ecological environment, more and more human contact with different animals.

Moreover, many animals from ancient times did not live close to humans, but now they are tamed. These special Asian animals are now included in the European table menu.

The modern structure of the food production industry leads to the situation that diseases occurring in cattle can threaten the lives and health of hundreds of thousands of people.

Climate change changes the habitat of migratory birds and insects (such as mosquitoes). They bring pathogens away. The changing environment of humans and animals also changes the mechanisms of action of different pathogens.

Laurie Garrett, author of the book 'The Future Plague', says that when animal pathogens have not yet infected humans, it is not known how large a pandemic scale is and no one can predict it. .

Here are 14 major diseases that humans suffer from animals:

first-   AIDS . People suffer from the HIV virus from humanoid gibbon species in Central Africa. Currently, nearly 24 million people die from this disease.

2-   Acute pneumonia . Humans may have spread the disease from civets. The epidemic hit thousands of people, hundreds of them died.

3-   Dengue fever . This pathogen is a mosquito. The first outbreaks broke out in the 1950s in Thailand and the Philippines. In the 1970s the epidemic spread to 9 countries. Sporadic outbreaks now occur in 100 countries.

4-   Ebola fever . There is a theory that humans are infected with this virus from human gibbons. Pathogens are transmitted through direct contact with the blood and excretion of the patient. In the 1970s, Ebola disease broke out in Sudan to kill 90% of infected people.

5-   Yellow fever . People spread the virus that causes this disease from humanoid apes in Central Africa. Mosquitoes are vectors. The first yellow fever cases were nearly 400 years ago. The yellow fever vaccine has been under control for 60 years.

6-   West Nil fever. Mosquitoes - vectors of disease transmission (Photo: health) Humans infected with the virus cause this disease from birds and through mosquitoes. This fever is dangerous from high mortality. The cases were recorded not only in Africa but also in Asia, Europe and North America.

7-   Malaria . The causative agent of malaria infects humans when it is burned by anoxic mosquitoes. Every year, nearly 300 million people get sick, one million of them die.

8-   Laima disease . People infected with pathogenic bacteria through deer and mice. Symptoms of the disease are like flu, but the disease occurs in more severe forms and causes arthritis. In the 1970s, the disease first occurred in the city of the same name in the US so it was brought there

9-   Smallpox . People spread camel disease. This disease is famous from 3000 years ago and for a long time is the main cause of death for children. Many famous historical figures are also victims of smallpox, such as Pie the Great of Russia and the French King Ludowic 15. According to the historians' evaluation, at the end of the nineteenth century each year there are nearly 50 million people get smallpox. The mortality rate from smallpox exceeds 30% of the total number of infected people. The last case of smallpox took place in 1977.

10- Monkey smallpox . People get this disease from yellow mice. The cases were recorded at the end of May last year in the United States. The disease also evolves as a smallpox but is milder and not fatal.

11- Bubonic plague . Humans are infected by rats and other rodents. The causative agent is transmitted through the bite. The first plague broke out in the 6th century and in Vizantia: In nearly 50 years nearly 100 million people died. In the fourteenth century, Eastern plague claimed the lives of about one-third of Asia and Europe's population. At the end of the nineteenth century, a third global plague struck over 100 ports in the world. In 1999 it broke out in 14 countries, mainly in Africa, with more than 2.6 thousand people infected, 212 of whom died.

12- Brain disease . (Often known for mad cow disease). People spread this disease from cows. In the sporadic world, there are a few fatal cases of eating beef containing pathogens that attack the brain. Cases of mad cow disease occur in different countries. This disease is harmful to European agriculture about 60-120 billion dollars.

13- Encephalitis . Humans receive encephalitis agents from rodents and birds. Mosquitoes and bugs are also vectors that carry viruses. Every year, 100-200 thousand people suffer from different encephalitis, 10-15 thousand people died.

14- Salmonella disease . People get it from cows, pigs, goats, ducks and geese when eggs and food have salmonella. There are also cases of death from this disease.
