Though the disease originates in Africa, researchers from the University of Wisconsin-Madison have put together a tuberculosis timeline which shows that it was largely spread by the Roman Empire.

TB is one of the world’s most prevalent and deadly diseases. According to the CDC, it affects one in four people around the globe and is the leading killer of those who are infected with HIV. In 2016, a staggering 10.4 million people were infected with the illness and 1.7 million tuberculosis-related deaths occurred.

Mycobacterium tuberculosis (M.tb) is the strain that many recent historical-research TB investigations focused on. According to bioRxiv, the same strain was also the subject of the 2018 study.

Another reason to travel, but you may actually learn something on this trip. DNA tourism is a growing trend for travelers that want to discover their own heritage.

Families are much more likely to be spread across the globe. Maybe you’ve relocated to another state or country for work and are situated in a foreign land. There are many other reasons why people don’t know much about their heritage; perhaps your parents don’t know much about their family history and can’t offer a tree to help.

But, websites like Ancestry.com and the fast-growing 23andMe offer a scientific solution.

By breaking down malaria, we may have another breakthrough in disease prevention.

Researchers have discovered how Plasmodium vivax (P. vivax) malaria parasites enter human red blood cells at the atomic level. The finding could allow scientists to create antibodies to stop various strains of the virus from infecting people.

The discovery was made possible with a Nobel Prize-winning technology called “cryo-EM”, or cryo-electron microscopy. Using a 3-D map, a team was able to visualize exactly what happens when P. vivax interacts with human red blood cells. The groundbreaking team hailed from the University of Melbourne and the Walter and Eliza Hall Institute of Medical Research in Australia and from the Howard Hughes Medical Institute in the United States.

Instagram made its first appearance in October 2010 and had 25,000 people sign up on the first day. Now, eight years later, it is one of the world’s most-used apps with at least 500 million users each day.

With its increasing list of appealing features, it is by far one of the fastest growing social media platforms to date.

Even with all these new features, the app is built on a pretty simple concept. Users post their own photos and videos, engaging with friends or viewers to keep people connected. Instagram is one of many apps that seems almost built for travelers with wanderlust. Influencers and ordinary people alike use Instagram to promote destinations and sites that are a must for anyone who has the travel bug.

At least seven states across the United States are dealing with hepatitis A outbreaks. Not only is Kentucky home to the worst of those epidemics, but with almost 1,000 confirmed cases, it now has the worst recorded hepatitis A outbreak in the country.

Approximately half of the 969 patients come from Kentucky’s largest city, Louisville, where the hepatitis A outbreak was first detected in the fall. Over 500 hospitalizations have occurred in the state with 300 of them being in the Jefferson County city.

So far, Kentucky’s outbreak has resulted in six deaths. Compared to other states with a hepatitis A outbreak, Kentucky’s death rate is significantly lower. Dr. Jeffrey Howard, the Commissioner of Kentucky’s Department of Public Health, told WDRB that he believes that the high hospitalization rate contributed to the low death count. Currently, the state is hospitalizing almost 59 percent of hepatitis A patients.

Cases of Human Papilloma Virus (HPV) have dropped in the United Kingdom.

A U.K. government report revealed an 86 percent decrease of the two types of HPV which cause most cases of cervical cancer. Released on June 18, 2018, the report focused on a certain sector of England’s population.

But, this wasn’t the only recent good news for HPV prevention.

After a year and a half of lab work, it was announced in June 2018 that a team from the University of Florida has discovered the first known case of a person infected with the Keystone virus.

Perhaps more startling is the thought from the study’s corresponding author J. Glenn Morris, M.D., M.P.H. Morris stated that the virus has likely been common in people in the Southeast for some time and we just lacked a way to test for it.

Malaria infected approximately 216 million people worldwide in 2016, according to the WHO. That same year, Uganda saw between 70,000 and 100,000 cases of the mosquito-borne disease. Currently, the only way to detect malaria is through a blood test.

At least, until a recent breakthrough from someone who has firsthand experience with those many cases in Uganda.

So, who is the person to invent such a non-invasive device?

There has been an increase in cases of dengue fever, along with many other infectious diseases worldwide.

Over the past 50 years, dengue fever incidence has increased 30-fold, according to Science Direct. Cases spiked to about 390 million recorded in 2010 alone. You can associate the rise in cases with globalization, demographic trends, and travel.

But, as of lately, environmental changes are also contributing. Warming temperatures have been behind the amplified spread of dengue fever.
