The History of Cholera and the Ganges Delta

February 6, 2018 by Will Sowards 2 Comments

The consistently dirty body of water is the source of many cholera epidemics.

While cholera outbreaks are still occurring today, these epidemics are nothing new. Most of the world’s cholera epidemics can actually be traced back to a single place: India’s Ganges delta.

Cholera is an intestinal infection spread through contaminated food and water. Symptoms of cholera usually include diarrhea, vomiting and leg cramps. The disease doesn’t always show those signs though. Sometimes cholera is present with no symptoms to speak of. If an individual does not seek treatment, the symptoms can quickly become severe and victims can die within hours.

Many of the world’s worst cholera outbreaks can be traced back to the Ganges delta. Due to the fact that cholera spreads through contaminated food and water, the Ganges is a perfect breeding ground for the disease. The Ganges delta provides a source of water for millions of people living in India, all of which could be using contaminated water to bathe or cook.

Why is Thimerosal Safe to Use in Vaccines?

February 3, 2018 by Will Sowards 1 Comment

The mercury in thimerosal puts off some, but the chemical doesn't actually pose a risk.

We naturally want vaccines to be as safe as possible. What’s the point in getting vaccinated if you’re risking a different illness?

While many people worry about side effects from vaccines, others don’t know about the other risks: bacteria.

While a syringe is injected into a vial, the vaccine can develop dangerous fungus. To combat this, manufacturers started to use a preservative called thimerosal. Thimerosal would prevent the fungus in multi-dose vaccines and make the drugs far safer.

How Much Does it Cost to Develop a New Vaccine?

February 2, 2018 by Will Sowards 3 Comments

With a greater need for vaccines, costs have also risen in recent decades.

Since the first vaccine centuries ago, immunizations have become more important. But, with mass vaccinations come high costs.

With less known diseases at the time, children only received two vaccines in the 1950s: smallpox and diphtheria. According to a report by Clinical Infectious Diseases, pediatricians were able to administer these shots for as little as a dollar.

The polio vaccine was administered for the first time in 1955 which became part of the immunization schedule for children. These three shots became the standard for quite some time. In the 1970’s and 1980s, only half of school-aged children were vaccinated.

Four Chinese Cities to Celebrate the Lunar New Year

January 31, 2018 by Will Sowards Leave a Comment

Celebrated around the world, China has the most lavish parties for the Lunar New Year.

The Lunar New Year, also known as the Chinese New Year and the Spring Festival, is just a couple weeks away.

The Chinese New Year dates back nearly 4,000 years and originated to raise sacrifices to the agricultural gods and ancient ancestors. This was a way of honoring them for sustaining the Chinese people for another year. Emperor Wudi of the Han Dynasty set the date from the lunar calendar. More than celebrating a turn of the calendar, the event signifies the beginning of the planting season.

The celebration may only land on one day, but the new year’s festival is a massive event covering 15 days.

Are We at Risk of a Bird Flu Outbreak?

January 30, 2018 by Will Sowards Leave a Comment

Officials are cracking down in three countries to prevent an outbreak.

Animals get sick just like humans, and feathered friends are no exception.

The bird flu, also called avian influenza, is very common and stems from two strains the virus, H5N1 and H7N9. The virus affects different kinds of birds including, but not limited to turkeys, ducks, chickens and wild turkeys.

Not only does the virus mutate quickly, but bird flu spreads easily in people who spend a lot of time around the animals. This leaves farmhands at great risk of starting an epidemic if their flock gets sick.

The bird flu has been resurging in the news of late. This is due to recent cases reported throughout the United Kingdom, China and Iran. Each country is addressing the problem accordingly by enforcing the laws and reevaluating farmers and their flocks. All governments are taking action to keep bird flu from the general public.
