With an evolving population of 4.3 million people, Croatia is known for its rich historical culture, beautiful landscapes and pleasant climate. As a result, Croatia has become a booming tourist destination. Although widely known for its attractions, many transmittable diseases in Croatia threaten the health of its population and the country’s tourism industry.

Here are just a few of the threatening diseases in Croatia:

Typhoid Fever

Typhoid fever is a systemic infection, usually contracted through contaminated food or water. The symptoms include prolonged fever, nausea, headache, loss of appetite and constipation or diarrhea. It thrives in areas with poor sanitation and lack of clean drinking water. According to a study published in 2014, approximately 21 million cases and 222,000 typhoid-related deaths occur annually worldwide, demonstrating the real threat that this communicable infection poses.

Currently, there are two typhoid vaccines that are recommended for use, including an injectable polysaccharide vaccine (Vi-PS vaccine) for persons of age two years and above. The other vaccine is a live attenuated oral Ty21a vaccine for those over five years of age.


Malaria is a life-threatening disease caused by parasites that are transmitted through mosquito bites. The symptoms include fever, headache, chills and vomiting, which usually appear within 7 days or more (usually 10-15 days). If not treated quickly, this can progress to severe illness, often leading to death.

Malaria is preventable and curable, easing the burden in many countries around the world. Currently, there are no licensed vaccines against malaria or any other human parasite. However, with insecticide-treated mosquito nets and antimalarial drugs, malaria can be prevented.

Hepatitis B

As a viral infection that attacks the liver, hepatitis B is a virus that is transmitted through contact with blood or other bodily fluids of an infected person. Every year, more than 686 million people die due to the complications of hepatitis B, including cirrhosis and liver cancer.

A vaccine against hepatitis B is available in preventing the infection and the development of chronic disease and liver cancer complications. However, the treatment does not cure all cases of hepatitis B. By only suppressing the replication of the virus, lifelong treatments are necessary in order to fight against the complications of the virus.

Although the diseases in Croatia are constantly threatening the health of the country’s population and its tourism industry, many are continuing to develop innovative methods to help bring vaccinations and preventable solutions to Croatia, potentially saving millions of lives.
