10 Weirdest Disease Outbreaks Of 2015

Bubonic Plague 


Bubonic Plague, also known as Black Death, still affects many people every year. In the 14th century, this plague killed around 60% of the European population and the CDC reported that there had been around 3 cases of this disease in the United States each year.

However, between April and August of the current year, this number rose to 11 cases. The CDC again reported in October that 4 additional cases had surfaced. This meant that there were a total of 15 cases for this disease in the year 2015.

The plague happens as a result of Yersinia pestis, bacteria that is transmitted through infected flea bites. For treatment, antibiotics need to be used, which need to be administered early on since the disease can become fatal really early.

In most of the cases, the disease happens in rural areas. In the United States, the disease was clustered in Nevada, Arizona, California, New Mexico, and Colorado.

Dengue Fever   


Mosquito bites are always really annoying. However, sometimes they come with weird infections and diseases such as dengue fever. This mosquito borne illness is the result of a dengue virus.

In the year 2015, there have been a minimum of 153 confirmed dengue cases reported by the officials on Hawaii. This can be categorized as a major outbreak within the country. Vietnam had a spike of more than 58,000 cases whereas Taiwan reported more than 41,000 cases and 195 deaths.

Dengue fever results in flu-like symptoms and then causes a fever, joint pain, and rash. And while there is no specified vaccine or treatment for the disease, there is supportive care such as acetaminophen, fluids, and getting plenty of rest. While it can go away itself with sufficient care, it can also become fatal and serious resulting in dengue hemorrhagic fever.



Leprosy was a disease of the past, but it has woken back up from the dead. However, you would be surprised to know that around 9 cases of the disease had been reported in Florida. Prior to this, the cases had usually been in between 2 and 12 in a year.

The outbreak was thought to be a result of construction and land development. This forced the natural disease carriers, or armadillos, to come in contact with other people.

The disease spreads between humans with contact from feces or blood of the carriers, also known as armadillos. These are the only animals to be known to have this unique bacteria strain causing the disease within humans.

Luckily, you can very well stay away from these armadillos and the fact that leprosy is a rare disease infecting only a few people within the country is also a disarming bit of information.



This disease is another reason why you should be avoiding mosquitoes. Chikugunya in 2015 was a condition that became nationally notifiable within the United States. There had been a report of 629 cases within 43 states and a total of 202 cases within the US Virgin Islands as well as the US territories of Puerto Rico.

All of these cases were associated through travel, which was most likely through Africa and Asia.

The disease is transmitted through infected mosquitoes and causes joint and muscle pain, headaches, and high fever. However, Chikungunya is not fatal.

Long term infection of the disease can cause disability and chronic illness. However, the great news is that recovery is possible and you will never be infected again.



Ebola hemorrhagic fever, a deadly virus, can spread through bodily fluids and blood from infected animals and humans. The disease can often lead to death.

Despite several African countries being affected severely, the disease has subsided to a great extent and is now under control.



WHO made an announcement in 2015 that TB kills more than 1 million people every year, and these figures tend to be more than HIV and AIDS.

Bacteria cause the disease when an infected person speaks, sneezes, or coughs. However, not everyone infected with the bacteria becomes sick since in the case of latent TB, the bacteria can reside within the body without doing any harm.



There have been 189 cases and 5 outbreaks of measles within the United States in only 2015. Most of these cases have been linked to a traveler who had been infected and was present at Disneyland in California.

Measles result in a runny nose, fever, body rash, and sore throat. The disease is extremely contagious and can spread through sneezing and coughing.



2015 resulted in the outbreaks of typhoid in Malaysia and Uganda. The disease is caused by bacteria transmitted through food or water that is contaminated by someone who has the infection.

A vaccine is present to prevent the disease. However, this might not be available in the low income countries having lack of clean water and poor sanitation.



Cholera is extremely dangerous, especially when it comes to young children. There were around 19,000 cases reported in the Democratic Republic of Congo and 8,835 cases reported in Mozambique. Other than this, there were outbreaks in Iraq and other East African countries as well.

Cholera is highly infectious and is caused by ingesting contaminated water having Vibrio Cholerae in it.

Bird Flu   


While bird flu did not infect a lot of people this year, it infected lots of birds, and as a result there was even a panic over the prices of turkey during the past Thanksgiving.

The avian flu came in four waves in 2015 and caused an outbreak among wild birds and poultry in about 21 states.
