According to the CDC, the Center for Disease Control and Prevention, more than 6 out of every 10 infectious diseases known to affect humans have their origin in animals.
Human unpreparedness
The head of the Chest Diseases and Intensive Care Department at St. George University Hospital, Dr. George Jovelkian, said in an interview with “Sky News Arabia” that diseases that are transmitted from animals to humans are more dangerous than others, because human bodies are not prepared to deal with viruses foreign to them, Pointing out that any new virus that the human body does not know, a pandemic occurs in the beginning, as happened with avian and swine flu.
According to Jovelkian, human immunity needs time to deal with strange viruses, and therefore we see that the first wave of any pandemic is violent, and its glare diminishes with the passage of time, due to the formation of societal immunity.
The bat is the mediator
Jovelkian explains that there are animals that have the possibility of transmitting more viruses to humans, such as the bat, because its composition and its burning and digestion process help it to catch many viruses, noting that often the bat plays the role of a mediator between the virus and humans, through direct or indirect friction.
He points out that humans have another relationship with virus-carrying animals through their upbringing, such as pigs, birds, cows and camels, and thus virus capture depends on the extent of the relationship between humans and the infected animal.
Virus capture key
According to Jovelkian, it is not necessary for any virus carried by the animal to be transmitted to humans, unless this virus has the key to enter the human body, and this is the main point in the matter as no matter how deadly the virus is in animals, except that if it does not have a “key” The human body”, the body’s immunity will repel it and kill it in its cradle.
The possibility of virus sharing has increased
As for Dr. Obada Medawar, a veterinarian, he said in an interview with “Sky News Arabia” that the infiltration of humans and animals into each other’s environments has increased the possibility of viruses sharing between them, noting that zoonotic diseases constitute a large proportion of all newly discovered infectious diseases.
The most mischievous animal
He pointed out that the causative agents of zoonotic diseases may be bacterial, viral or parasitic, and the mechanism of transmission of these diseases is often through direct contact with animals or their waste, or even by eating contaminated food products or water, warning that the most harmful animals to humans, It is rodents such as rats and mice that transmit dangerous diseases.
According to Mudawar, governments’ adoption of an approach that combines public health, veterinary and environmental expertise, contributes to preventing the outbreak of zoonotic diseases and preventing the next pandemic, stressing the role that personal hygiene plays when mixing with animals on farms, which may contribute to limiting the emergence of unwanted viruses.
