Dogs are often regarded as "man's best friend," but not all canine encounters are friendly. Some are outright fatal. In 2020, there were 46 dog bite-related deaths.

Before you eye your beloved pooch as a furry harbinger of doom, however, be aware that most deaths due to dog bites involved dogs that were not family pets, and most victims were unfamiliar with the dog.

Dog attacks can usually be avoided by exercising caution and good animal handling when approaching or dealing with an unknown animal.

Almost everyone has experienced some kind of insect sting or bite at some point in their lives. What is an annoyance for a vast majority of people ends up being lethal to an unfortunate few. The Centers for Disease Control and Prevention recorded a total of 1,109 deaths due to stings from bees, wasps, and hornets for the period 2000-2017.

Unfortunately, this number is likely underreported due to the misdiagnosis of fatal allergic reactions as heart attacks or sunstroke.

Caution should be exercised to avoid bee and wasp nests when outside for work or leisure, and those aware that they are allergic should carry antidotes or epinephrine in case of unavoidable stings.

In the United States, thermal burns account for almost 75,000 hospitalizations each year, with approximately 14,000 of them being fatal. These injuries come from a wide variety of sources such as contact with hot metals to scalds from liquids and oils used in both residential and commercial kitchens.

Proper caution, including wearing protective gear, should always be used when working with exposed hot surfaces and substances.

Modern humans have mastered many aspects of the natural world, but the weather is not one of them.

In 2021, storms killed 538 Americans, making it the deadliest year for weather-related deaths since 2011.

People living in areas prone to extreme weather should heed precautions such as having emergency stores of food and water and listening to evacuation warnings.

The vast majority of deaths by sharp objects are intentional homicides. According to the United Nations' 2019 Global Study on Homicide, fatal stabbings with knives accounted for 22% of homicides worldwide in 2017, the most recent year for comprehensive data.

That being said, sharp objects are dangerous under the best circumstances and accounted for the injury-related deaths of more than 3,100 Americans in 2020.

Proper protective gear and practices should be used when near sharp objects, and usual precautions against violent crime such as situational awareness should be practiced at all times.

With 2022 setting record temperatures in many places, there was also an increase in incidents of heat-related illnesses and deaths. Sunstroke or heatstroke—bother terms referring to the same condition—occurs when the internal body temperature rises over 104 degrees Fahrenheit.

People who exert themselves at work or in athletics in high temperatures are particularly prone to heatstroke, as well as children and the elderly.

Limiting physical activity in hot weather, drinking adequate quantities of water, and taking breaks from the sun are effective ways to avoid heatstroke.

We all have to eat. Unfortunately, one of the very acts required to live can sometimes be fatal. Statistics from 2020 showed choking as the fourth-leading cause of unintentional death, with a reported 4,963 deaths. Death by choking on food is particularly dangerous to the elderly.

Food should always be cut into manageable bites and thoroughly chewed before swallowing, and people with compromised swallowing abilities should be monitored while eating.

Fire can be both a help and a horror to humans. 2021 was a particularly bad year for fire-related deaths, with fires claiming the lives of 3,800 civilians and 70 on-duty firefighters. The majority of these incidents were the result of home fires.

Having fire alarms and extinguishers in all buildings and knowing points of evacuation increase survival odds against fire.

Whether from an armed robber or mass shooter, violence involving guns is a grim part of life. Homicides by firearm caused the deaths of 20,966 Americans in 2021, an increase of 8.3% over 2020.​​

Exercising awareness around other people at all times is the first line of defense, followed by knowing escape routes and cover, and if all else fails possessing self-defense skills.

People try to keep their balance as best as they can, but trips and stumbles are a part of life, and everyone has fallen at some point.

Falls range from being innocuous to fatal, with the elderly population being particularly at risk with fatal fall rates for seniors over 65 climbing approximately 30% from 2009 to 2018.

Falls in the home can be prevented by clearing tripping hazards from floors and stairs and installing equipment like rails in appropriate places.

Vehicular safety has come a long way in the past century, but it is still far from perfect. The National Highway Traffic Safety Administration estimates that 42,915 deaths due to vehicle crashes occurred in 2021. This number is up a grim 10.5% from 38,824 in 2020.

Practicing basic driving safety, wearing seat belts, and buying vehicles with modern safety features will increase the odds of surviving traffic accidents.

Despite advances in mental health care, suicide remains a leading cause of death in the U.S. Provisional CDC data shows a projected 47,646 deaths by suicide in 2021.

While the good news is that this number is slightly down from the record high of suicide deaths in 2018, the number remains significant and represents an increase after back-to-back years of decline.

Obtaining mental health care and not abusing substances such as drugs and alcohol are important factors in preventing suicide.

American deaths from opioid overdoses have been rising for the better part of a decade, with 2021 having 80,816 opioid-related deaths, up more than 10,000 from 2020.

Opioid deaths cut across all levels of American society, all ages, and economic statuses with deaths particularly on the rise in rural areas.

Education about opioid risks and improved access to health care and substance abuse prevention are effective ways of preventing opioid deaths, but the epidemic remains a lethal scourge.

Chronic lower respiratory disease is a category of illness comprised of chronic bronchitis, asthma, and emphysema. Together, they are the fourth-leading cause of death in the U.S.

The causes for these diseases are varied among exposure to environmental contaminants, smoking, infections, and genetic predispositions.

Treatment depends on the individual condition and its respective causes, but smoking cessation, avoiding pollutants such as asbestos, and medical intervention can increase survival odds.

Any cause of death that is neither natural nor intentional can be classified as an injury-related preventable death. This includes several manners of death that have already been mentioned, such as motor vehicle accidents and falls, but also includes any other cause of death that occurs unintentionally.

Within this category, poisoning has been the leading cause since 2013. Since these causes of death are so varied, so are the prevention methods.

COVID-19 has been merciless since it arrived in the U.S. In just a few years, it has been responsible for more than 1 million American deaths and nearly 100 million cases.

Potential infection can be averted by getting appropriate vaccines, practicing strict cleanliness behaviors to avoid other forms of infection, and keeping current with CDC recommendations.

Despite detection and treatment advancements, cancer is still one of the leading causes of death worldwide. While still shockingly high, cancer deaths have actually been decreasing over the last 20 years.

In 2020, 602,350 Americans died from cancers of all categories, with lung cancer alone being responsible for a little more than 1 in 5 of those deaths.

Cancers vary widely over genetics, sex, and environmental factors, but avoiding known carcinogens such as smoking tobacco and early detection for conditions like breast and colon cancers are significant to surviving cancer.

Across racial lines of race, ethnicity, sex, and social status, heart disease is the world's leading killer. The U.S. is no exception; approximately 697,000 people died from heart disease in 2020.

Since heart disease refers to various cardiovascular disorders, the causes are numerous, and potential risks will often depend on factors including heredity, environment, and diet.

Luckily, there are many behaviors individuals can manage such as modifying diet and exercise to maintain a healthy weight, avoiding or quitting smoking and drinking alcohol, and following up with doctors for routine screenings, especially with age.
