5 Things You Won’t Believe Are Contagious

Certain viruses, bacteria and parasites get all the attention for being contagious. If a friend happens to pick up Covid-19, ringworm or lice, we’re probably going to give them a little extra space for a while. Despite the many diseases we know spread from one person to another, there are still plenty we are not even aware of. On top of that, you can catch things from other people that Clorox wipes and hand sanitizer are powerless against. Laughing and yawning are well-known to travel from one person to another.Between sneaky bacteria and behaviors we believed were under our own control, there are numerous infections we are all spreading amongst ourselves. Read on to discover 5 things you probably didn’t know you could catch from someone else

1.cancer

There are three animals that currently suffer from transmissible forms of cancer.Tasmanian devils spread facial tumors through bites, dogs transmit venereal tumors through sexual contact, and soft-shelled clams spread their infected cancerous cells through seawater. These findings over the last few decades have drastically changed our knowledge of cancer’s ability to become a contagious disease.While humans are not yet known to easily transmit cancerous cells from one host to another, there have been documented cases where certain circumstances allowed just that to happen. In 2018, an organ donor died with undiagnosed breast cancer. Four people received transplants of her organs, and all four of them developed breast cancer. In another case, an HIV-positive patient contracted cancer from a tapeworm in his intestines. In all of these examples, the patients who caught cancer from another host had compromised immune systems. Scientists currently believe that contagious cancer is highly unlikely to occur in humans outside of these unusual situations, though the development of transmissible cancer in animals shows how that can change.[6

2. ulser

Stressful lifestyles and spicy foods have often been wrongly accused of causing peptic ulcers. In reality, the main cause of stomach ulcers is a bacterium called Helicobacter pylori.More than half of the world’s population is infected with the bacterium. For reasons not yet understood, some people never suffer any symptoms of H. pylori, while others develop peptic ulcers in the stomach and small intestine because of it. The ulcer-causing bacterium is contagious through saliva and fecal matter, so swapping spit and poor handwashing practices could land you an ulcer.

3.Heart disease:

Heart disease has long been considered a noncommunicable disease, a result of genetics and lifestyle choices. Earlier this year, a team of fellows in CIFAR’s Humans and Microbiome program provided evidence to the contrary. They found that heart disease, as well as other diseases such as IBS and type 2 diabetes, can also be contagious.The team began with the basis that all these diseases coexist with an altered microbiome, the mix of bacteria, fungi, and parasites that exist in our gut. When these altered microbiomes are installed in animal models, they create disease in their new host. The unhealthy microbiome that causes these diseases is what spreads from person to person similar to how a stomach bug does.Whether or not a healthy microbiome can be passed from one person to another is still being researched.

4.High blood pressure

High blood pressure, often associated with unhealthy diet and lifestyle choices, was discovered to also be linked to a very common contagious virus.A team of researchers discovered that mice infected with cytomegalovirus, or CMV, developed higher blood pressure than those without the virus. That’s not to say diet doesn’t play a role—mice infected with CMV who also binged on high-cholesterol foods had the highest blood pressure rates. The researchers also conducted trials with human cell cultures. The human cells infected with CMV created a protein already known to contribute to high blood pressure.CMV is estimated to affect between 60 and 99% of adult humans worldwide. The virus is transmitted through the sharing of bodily fluids and stays in your body for life.

5.loneliness

Ironically, loneliness is contagious. While it might seem like a group of lonely people would have something in common and therefore not be so lonely, it doesn’t actually work that way. A long-term study of over 5,000 people and their social relationships showed a traceable spread of loneliness from one person to another.People begin experiencing feelings of loneliness before they become entirely isolated. This means people start feeling lonely when they are still spending time with friends, which is how they share their feelings of loneliness with others before adopting a hermit lifestyle. Those transferred feelings of loneliness take root in the next person, and the cycle continues.We’re more susceptible to catching loneliness from friends than from family, and women tend to be more affected than men.
