Next Pandemic? Cases of Pathogens Jumping from Animals to Humans Are on the Rise

WHO warns that pathogens that jump from animals to humans are becoming more common.

The World Health Organization's (WHO) emergency director, Mike Ryan, warned that endemic illnesses like monkeypox and lassa fever are becoming more chronic and prevalent.

Anima-Human Interaction

People gain much from animals. Many individuals have everyday interactions with animals, both at home and away from home. People all across the world rely on animals for food, fiber, livelihoods, travel, sport, friendship, and education. In the United States, millions of homes have one or more pets. Animals may be encountered in urban or rural environments while traveling, visiting animal displays, or participating in outdoor activities.

Zoonotic Diseases

Animals, on the other hand, can occasionally carry hazardous bacteria that can transmit to humans and cause illness; these are known as zoonotic illnesses or zoonoses. Viruses, bacteria, parasites, and fungi are all responsible for zoonotic diseases. These viruses may cause many ailments in humans and animals, from moderate to severe sickness and even death. Depending on the zoonotic illness, animals might seem healthy even though they harbor germs that can make people sick.

In the United States and worldwide, zoonotic illnesses are relatively widespread. According to scientists, more than 6 out of every ten recognized infectious diseases in humans are transferred by animals, and animals carry 3 out of every 4 new or emerging infectious diseases in humans. As a result, the CDC works around the clock to safeguard humans in the United States against zoonotic illnesses.

Spreading Pathogen

Animals and humans modify their behavior, particularly food-seeking routines, as climate change leads to quickly changing weather conditions like drought. Pathogens that generally circulate in animals are increasingly crossing into people due to this "ecologic fragility," he added.

"Unfortunately, the potential to amplify that sickness and spread it throughout our communities is growing, so disease emergence and disease amplification factors have grown."

According to him, there is an increase in instances of Lassa fever, an acute viral infection carried by African rats.

"We used to have three to five years between Ebola epidemics at the very least," he continued. "Now we're lucky if we get three to five months."

"There's an ecological strain in the system," says the researcher.

His remarks come as the number of instances of monkeypox outside of Africa, where the infection is prevalent, continues to climb.

Assessments

Since the initial report in early May, the WHO said it had received reports of more than 550 confirmed cases of viral illness from 30 countries outside of Africa.

Meanwhile, while COVID-19 instances are dropping globally, there are worrying tendencies in some places, including the Americas, according to WHO Director-General Tedros Adhanom Ghebreyesus.

Officials in North Korea believe there are over 3.7 million cases of fevered persons in the country, which might be COVID, as the government fights its first-ever COVID outbreak. It declared a state of emergency and ordered a statewide lockdown.

Although the WHO had given the country vaccines, medicines, and other medical supplies, Ryan said the organization has had difficulty obtaining raw data that would represent the reality on the ground.

COVID's experience has prompted the WHO to draft and negotiate a worldwide convention to improve pandemic prevention, preparedness, and response.

Affecting Everyone

According to Ryan, pandemics, like climate change, affect every population.

"We've seen the challenges we encountered in this pandemic; we may face a more severe pandemic in the future, and we'll need to be a lot more prepared than we are today," Ryan said.

"We need to build a playbook for how we're going to prepare and respond as a team; it's not about sovereignty; it's about accountability."
