Come flu season, every person of all ages is at risk of influenza. Every region across the world is susceptible to the contagious respiratory illness. Being different than a common cold, the flu can take effect suddenly and can range from mild to severe in illness.

While many sick with the flu tend to recover within two weeks, some people can develop complications.

One of those complications can lead to pneumonia. According to Everyday Health, one-third of pneumonia cases develop from a respiratory virus, with the flu the most common of those.

Many people likely weren’t familiar with monkeypox until September 2018 when major news broke from officials that the United Kingdom had its first ever case of monkeypox.

One month later, a total of three patients have been diagnosed in the country. Though further cases are unlikely, the incident has built up some concern. Travelers and healthcare workers alike worry of the deadly disease.

As epidemiology (the study and analysis of the various factors of health and disease events) shows us, knowledge is imperative to preventing the spread of many diseases. So, how did three people get the monkeypox virus in England in the first place? And what risk does the disease pose to people who may have been exposed to it?

Four new diseases pose a risk to travelers to tropical areas. The FDA recently added Lassa fever, chikungunya, rabies and cryptococcal meningitis to the Tropical Disease Priority List.

In a press release, the FDA’s Chief Scientist RADM Denise Hinton addressed the need for these additions. She noted that the list encourages new treatment for these diseases. By prioritizing them, we could see a push for new medicines or vaccines that could help the millions of people who live in these areas.

We’ve seen recent evidence of the effects these diseases can have on tropical regions.

In many parts of the world, yellow fever is no longer an issue. Yes, some parts of the world still have regular bouts with the disease, but medicine and vaccines have helped with that problem.

Although, not so long ago, the disease was responsible for terrible epidemics. People were forced to flee their homes with the fires still burning.

Scientists estimate that yellow fever originated in Africa around 3,000 B.C. It started with a smaller impact in local villages, growing in range to large cities.

Most people consider a toilet seat to be dirty, but did you know that the average cell phone is thought to be 10 times worse?

Scientists estimate that mobile phones contain over 25,000 bacteria per square inch. A study published in the U.S. National Library of Medicine noted found that the phones of secondary students in Estonia had approximately 17,032 bacterial gene copies per phone. These are statistics that certainly grab attention.

While this information should encourage you to clean your hands (and your phone) more often, don’t panic.

Although the 2020 Summer Olympics in Tokyo are two years away, experts are already worrying of a possible dengue outbreak.

In 2014, Tokyo suffered an outbreak of dengue fever, with 34 individuals affected. Experts are worried that with such a large amount of people coming to the games, the risk of the virus spreading quickly will greatly increase.

Dengue is a mosquito-borne illness, spread to humans by infected mosquitoes. The insects contract dengue when they bite a person who has the virus. From there, the infection spreads. Humans can’t directly spread the disease to others.

The topic of latent tuberculosis has been a subject of debate recently. How common is it really?

Tuberculosis is a lung disease transferred from person to person by infected particles in the air. This makes tuberculosis highly contagious. But, even though the disease is airborne, not everyone who comes in contact with TB will become infected.

There are two types of tuberculosis: tuberculosis disease and latent tuberculosis.

We know the ongoing dangers of tuberculosis disease. Even with the help of modern medicine, tuberculosis continues to be one of the world’s most dangerous diseases.

Like many parts of the world, Africa is growing, and doing so fast.

And, with population rising, Central Africa is also becoming much more urbanized. Over half of Central Africa’s population are expected to live in cities within the next 20 years.

For many in the region, these changes are largely seen as a positive growth. Although, disease and outbreak risks are also rising with increased urbanization.

Polio is a nightmare of the past for most of the world thanks to life-saving vaccinations.

But, in the Democratic Republic of the Congo, Syria, Somalia, Kenya and now Papua New Guinea, recent outbreaks have brought a resurgence of the incurable disease where it was once eradicated.

Twelve children in five provinces of Papua New Guinea have been diagnosed with polio since July.

Hundreds of people have died in Brazil’s largest yellow fever epidemic in over 100 years.

A major and unexplained resurgence of yellow fever in Brazil occurred in non-human primates in 2016. The outbreak then spread to humans in early 2017, taking almost 700 lives.

Thanks to a detailed study from Oxford University, we now know how the virus spread in the 2016-2017 Southeast Brazilian outbreak. Not only does it give insight into this outbreak, but could help stop future epidemics around the world.
