The South American Yellow Fever Outbreak and What You need to know

Yellow fever has become one of the first travel panics of 2018 with widespread reporting of the disease outbreak in South America and Africa. Most recently, the outbreak in Brazil has caused a lot of concern, but how much do you need to worry about it and is there anything you can do to protect yourself from it? Here, we’re going to look at what you need to know about the South American Yellow Fever Outbreak.

Where Yellow Fever occurs

There are currently 47 countries where Yellow Fever outbreaks have been recorded. Though the recent news has shown an outbreak in Brazil and South America, 90% of all Yellow Fever cases are recorded in Sub-Saharan Africa. Yellow fever can go on to spread in other countries if someone who contracted the virus enters it, but because the transmission is caused by mosquitoes, it does not spread easily in countries that don’t have them.

How it’s transmitted

As mentioned, yellow fever is most commonly contracted from mosquitoes. It is most commonly found in the Aedes mosquito but has been contracted from Haemagogus mosquitoes, too. These insects bite an infected human or monkey which then leads them to infect others by biting them, too. Yellow fever does not spread directly from human to human, so areas, where mosquitoes are most common, are those at most risk. These include jungles and densely populated areas with poor water sanitation and still water. There are yellow maps of Brazil available online that show all the areas where vaccination is currently recommended.

Symptoms

As the name suggests, the first symptom of the virus is a strong fever that produces after 3 to 6 days of being bitten. It’s joined by stomach pains, severe headaches, shivers, nausea, and vomiting though not all symptoms may show.

The majority of people who contract the virus recover from this fever, but others go into a more dangerous second phase. Patients become jaundiced, tinting the skin and the whites of the eyes to yellow, leading to the name of the fever. The fever will worsen and bleeding from eyes, nose, mouth and, stomach can occur. In some cases, kidney function can deteriorate. This is the most dangerous phase, with 50% of patients who enter it dying in 10-14 days, while 50% recover without organ damage.

Yellow fever can be difficult to diagnose because it shares symptoms with several other diseases, from the early stages representing the flu to the later stages looking similar to malaria, dengue fever, and the Zika virus. All of these diseases are spread by mosquitoes, particularly the Aedes mosquito. If you’re concerned you have contracted the virus, you will need a blood test to prove it.

Treatment

Yellow fever does not have a specific treatment once it has been contracted. There is no cure if you get it, but it has been shown that hydration and treatment of the fever and its accompanying bacterial infections can increase survival rates in those who progress to the second stage of the disease. While there is no precise treatment once you have contracted the disease, there is a vaccine widely and cheaply available that has a success rate of over 99% that you can get before going to a country with a yellow fever outbreak.

Prevention

The single most effective way of stopping yourself from contracting yellow fever is to get the vaccination. A single dose, which costs less than $2 provides lifelong immunity. It is not required for entering Brazil or some other countries, but it is highly recommended. However, there are other precautions you should take when traveling, too. Mosquito control using repellent sprays, bug nets and staying away from areas with dirty or stagnant water can help you avoid the insects. Remember, mosquitoes are responsible for transmitting multiple blood-borne diseases and causing bacterial infections, not just yellow fever.

Vaccinations

The yellow fever vaccine has been available for decades and is widely used by those traveling to Brazil and South America. Try to get your vaccination at least ten days before entering the country, as it has a 90% successful inoculation rate in ten days and a 99+% effectiveness after thirty days. As mentioned, the vaccine is cheap and provides lifelong immunity, with only minimal side effects like low-grade fevers, headaches, and muscle aches. Everyone older than 9 months should be vaccinated.

While Yellow Fever is serious and can be contracted quite easily, it shouldn’t be a concern for most travelers. A safe and affordable vaccine should be all you need to enjoy your trip to South America without fear of contracting it.

Measles Outbreak in Europe

 Measles Outbreak in Europe

The World Health Organization (WHO) has stated that the number of measles cases in Europe has grown by 400% in the last year, taking the total to 21,315 cases in 2017. For anyone traveling to Europe, this obviously poses a fairly significant problem. Nobody wants to go somewhere if there’s an outbreak of a pretty serious disease floating about. Particularly when cases of the disease are rising. You may be wondering; why is measles on the rise, and is it still safe to travel to Europe?

It’s fair to say that society would score me a ten out of ten on risk-taking and risk tolerance. So far in life, I’ve dropped out of college to manage a rapper, quit back to back high-paying startup jobs within six months of each other, and decided to move to Asia for six months (which has since stretched to nine) with a half-baked plan.
