There are so many animals with potential infection risks, how can people distinguish them? In fact, as long as certain contact limits are observed, especially for wild animals, most people will not be in danger. Today’s “Girlfriend” brings an easy-to-understand guide to contact with animals.
1 Insects: Demonized Little Thing
Many people think insects are dirty, on the contrary, insects are quite safe for human beings (ticks, spiders, scorpions, etc. are not insects). They are too far related to human beings and seldom suffer from common diseases. In the wild, most insects can be directly touched by hand, but a few poisonous insects such as bees and poisonous ants cannot be touched, but they can also be observed at close range.
Generally speaking, most insects are harmless to human beings. A small amount of them sting and bite. Most of their own diseases will not be transmitted to human beings. Only a very small number of species, such as mosquitoes, flies and trypanosomes, can transmit diseases. However, in the huge category of Insecta, it is a very low proportion.
Believe it or not, you think the dirtiest cockroach, although it carries germs, has not caused even a plague?
Mammals: Cute but High Risk
Many people saw insects chirping, but when they saw mammals, they were determined to embrace them. In fact, it was very dangerous. Mammals are closely related to human beings, and their germs and parasites often infect human beings. Moreover, the hair of mammals is easy to hide dirt, and the extent of their dirt is hard for us to imagine.
Hedgehogs sometimes appear in big cities. Urban people often hold them up and admire them. However, careful observation shows that many wild hedgehogs are full of ticks and will climb down to bite people in an unguarded moment, spreading hemorrhagic fever, forest encephalitis and other diseases.
Not to mention bats, even professional scholars have to wear gloves when they have to hold bats and clean them well afterwards. However, the “nature education” tour groups that are springing up in some cities actually take their children into caves, allowing them to directly use their hands to pull the wings of bats to take pictures! This is a very dangerous act, we must not imitate it.
The intermediate host of the epidemic is probably mammals. For wild mammals, we should be the most careful, keep a distance, can not touch don’t touch.
Marine life: selectively touch or not touch
Generally speaking, ordinary people have two completely different views on marine life: first, what can’t be touched with seafood? Second, who knows what is poisonous in the sea? Don’t touch it!
What should we do then? One simple way is to touch only what you know when you stroll along the beach. Don’t touch anything while you are swimming or diving.
When strolling along the sea, we usually encounter intertidal creatures, such as oysters, shells, crabs, small fish, etc. Most of them are still safe. However, there are also some individual fish, such as basket fish, which are harmless to human beings and animals. In fact, each fin is poisonous. If it is pierced, it will cause terrible pain.
When practicing diving, a professional diving coach will generally tell you a rule-don’t touch anything when diving, whether there is life or not. Underwater, there are too many poisonous species: jellyfish and anemones may sting you; Coral polyps can also sting people; The rose catfish, which is highly toxic on every fin, will disguise itself as a stone and will be caught accidentally.
Fear of nature, human beings are not as powerful as they think.
Life is beautiful, but our danger always exists. In the process of taming nature, many viruses will acquire the ability to survive in human beings and run from nature to human beings-
Bird droppings and chicken droppings are mixed together. After the virus has evolved, bird flu is found in people.
Some people went to Africa to see the antelope and came back with sleeping sickness.
Some people were thrown into the dirty water of the pigsty, and their eyes were infected by the porcine herpesvirus, resulting in blindness.
Some people cut wild fish, stabbed and cut their hands, infected with traumatic bone bacteria and nearly amputated their limbs. ……
Therefore, every time an infectious disease occurs, scientists have to find out what the virus is, where it came from, and what drug to kill it with. This is a great project. Fortunately, after so many years of fighting against the virus, human technology and experience are developing. Unfortunately, until now, there are still people who do not realize the horror of nature and think that human beings have tamed all natural things, but do not know that they will also become the source of infectious diseases.
The reason why human beings have not been exterminated by infectious diseases is thanks to the doctors who have been giving silently from ancient times till now and the service personnel of the public health system, who are the barriers between us and viruses and bacteria!
