Climate Change may Directly Impact The Transition of Animal-to-Human Disease

Animal-to-Human Disease may be Influenced by Climate Change

In recent studies, it was found that the number of cases of zoonotic diseases transferred has increased in the past few years.

Researchers suspect that this is due to the very discrete changes in our ecosystem.

In the Ebola outbreak which started in 2013, it is seen that climate factors might have played a very important role.

With these recent advancements, many universities and private researchers are pouring their minds to create a broader view of these situations.

 Animal-to-Human Disease

The Swansea University researchers and the researchers of Queensland University are focusing on various different environmental factors which can lead to the transfer of diseases from animals to humans.

We as humans are very susceptible to change.

Ever think about exposure to lethal diseases due to contact with some cute puppy or any rodent that we encounter on a daily basis.

Yes, there are various diseases which one can get due to exposure to some animal which originally has a pathogen to which the human immune system is not compatible with.

It is true to a varied extent that these ecological and environmental changes like melting polar caps and global warming are only fueling these occurrences.

So, when something foreign enters our body, like a pathogen against which the immune system does not have any prior experience, it increases the chances of that pathogen causing some major problems.

The same happens when there are ecological changes.

The bacteria, fungi and viruses adapt and evolve accordingly resulting in serious outbreaks as our bodies do not have the immunity or any other type of protection against these new pathogens.

When we encounter a disease-causing factor, with time our bodies develop immunity against that particular disease.

But with multiple variables like evolving pathogens which keep presenting themselves, it does not leave us with enough time to fight against them.

All this is happening because of some changes in the ecosystem.

Disease-causing factors arise all the time.

What is important here is that if we are able to stop, prevent and cure them. Anything foreign messing with the body of an organism is generally bad.

Researches show that with climate change, the rate of transfer of zoonotic diseases may also change.

In recent studies, it was found that the number of cases of zoonotic diseases transferred has increased in the past few years.

How are Zoonoses transmitted to humans

Zoonoses are diseases which humans get from animals.

It is no surprise that animals are prone to some viruses and bacteria which can prove to be dangerous if exposed to humans.

Everyone gets it if they are wild animals which have close to zero human interaction.

 Animal-to-Human Disease

In such cases, they might have some pathogens to whom those animals have developed immunity with time but we have not.

In these cases, the risk of that animal to carry some disease-causing pathogens are quite high indeed.

Human transmission occurs mostly due to external contact.

Sometimes in zoos, there are animals from different parts of the world which might be carrying diseases lethal to the people in that part of the world who do not have any immunity to that disease whatsoever.

These are mostly worst case scenarios. Diseases like rabies are generally transmitted by infected vertebrates.

If a rabid dog bites someone the virus enters the body of the victim through the infected host. Thankfully we have remedies for that.

There are diseases, minor ones which do not spike much attention but are also zoonoses.

Tapeworm and influenza can be kept on that list.

These are generally transferred through pets. Obviously, the pets are generally well vaccinated but can’t be protected against these minor infections.

Getting sick because of playing with a dirty animal is one thing but what if the pathogen is present in the daily food?

There have been cases before where people got sick because of eating contaminated dairy products.

Another way of getting one of these diseases is by wild animals which are hunted and consumed.

Mosquitoes and other insects could also act as carriers. The pathogen does not affect them but can be harmful to us.

Can you get sick from your dog licking you

Can you get sick from your dog licking you

The answer to that question is pretty obvious.

Yes, there is a chance that you might get sick doing such activities with your dog. A dog serves as a host for various types of bacteria.

When he licks your face the chances of them entering the bloodstream are very high.

For a normal healthy person, it might not be very bad for the health but in rare cases, the contact can cause very serious problems.

The worse it can get is if the person gets the capnocytophaga infection.

Can a dog get sick from a human

We have justified that there are some diseases that dogs can transfer to us but there are not many that we can transfer to them.

It is not like there is no harm in keeping a dog with a sick human being.

In some cases, humans can make a dog ill. A not minor cold or flu though.

The virus that affects us does not seem to affect them in this case and the virus that affects them does not seem to affect us.

So, it is all right to keep your dog close while experiencing a minor cold.

But some diseases like tuberculosis, salmonella, Methicillin-resistant Staphylococcus aureus, etc also affect the dog.

Therefore in any case of anyone diagnosed with one of these diseases should limit their contact with their dog.

What diseases can be passed from animals to humans-

Having very different immune systems and due to evolution, many bacteria and viruses present in some animals do not affect them.

But when they are in contact with humans, lead to cause some diseases which in various occasions turned out to be very dangerous and sometimes even caused epidemics.

•  Anthrax
•  Australian bat lyssavirus
•  Brucellosis
•  Cat-scratch disease
•  Cryptococcosis
•  Giardiasis
•  Hendra virus
•  Hydatid disease
•  Leptospirosis
•  Listeriosis
•  Melioidosis
•  Psittacosis
•  Q fever
•  Ringworm
•  Salmonella
•  Sparganosis
•  Tetanus
•  Toxocariasis
•  Toxoplasmosis

Can humans get scabies from pigs-

Yes, scabies is very contagious. Research shows that for pig handlers whose pigs have scabies, some of them also have them.

When scabies comes from animals to humans, most of the times it results in a minor rash as they are not able to reproduce in human skin.

But it does not change the fact that they can be transferred from one body to another. So, yes humans can get scabies from pigs.

They are pretty easy to let go by following proper and easy treatment and can be prevented beforehand by following proper hygiene.

Can you get diseases from animal blood-

There are not many but Ebola was introduced to humans due to animals and ebola transfers from one body to another with the help of blood contact.

The epidemic of this single type of virus caused cost us many lives.

There is no telling when a deadly pathogen like that can be present in any sample of animal blood/ therefore it is always advised to steer away with contact from animal blood.

Can humans get STD’s from animals-

It is taken into account that many sexually transmitted diseases originally came from animals.

There are many STD’s that we and many animals have in common like the Chlamydia, brucellosis, etc.

Renowned specialist Mr. Alonso Aguirre tells that 2 out of 3 sexually transmitted diseases came first in animals.

Which Animal Carries The Most Diseases-

Bats - 1st in the list they are known for transmitting several diseases as Ebola (causes several internal and external bleeding and kills about 25 to 90% of vitamins), Hendra Virus, Histoplasmosis, and Marburg hemorrhagic fever.

Research teams have concluded that there are a lot of unidentified diseases which a bat causes and they can carry an additional 17 zoonotic viruses that are not identified till now.

With several virus carriers primates can be put in second in this list they are a major source of the animal to human diseases.

Some diseases caused by primates are herpes B Yaba virus, monkeypox which is though rare but life taking.

Coming to third, Rodents known for wiping away a lot of population of Europe in the mid-1300s.

It is stated by many studies that rodents living in Central Africa and South America and in North infect humans.

Rat bite fever comes under global reach, rats and other rodents too carry Yersinia pestis (which kill about 2 to 10 people only in the US each year).

2.2 million people die year-round by the infectious diseases caused by animals.

Can You Get Pink Eye From Animal Poop-

A pink eye is a very common disease in India, more than 10 million people face this every year only in India.

It spreads easily, self diagnosable, treatable and remains for a short period only.

A pink eye can be from many reasons it is not that it is caused only by animal poop but yes pink eye can be caused by it.

In most cases, pink eye is caused by Viruses which clear up on its own. It too is caused by Bacterias which may leave serious damages if left untreated.

Can You Get Sick From Your Dog Licking you-

Yes, Capnocytophaga bacteria which is found in a major proportion in dog's saliva can cause serious illness in humans.

Dog saliva is fastly absorbed by membranes near mouth, nose, and eyes and therefore pet should not be allowed to lick near the face.

But 2,3 licks are not much harmful.

Some diseases that might be caused- upset stomach, fever, vomiting, diarrhoea, nausea, Giardia, Salmonella, Leptospira, Campylobacter and Clostridium.
