World’s Most Dangerous Countries To Visit In 2025
A new study on security, health, and climate change risks around the world has revealed which countries are the most dangerous.
When you read the news and listen to the conversations happening around you, it can feel like there’s not a single place in the world that isn’t dangerous at the moment.
But the actual list of the world’s most dangerous countries to visit in 2025 has been revealed after a new study ranked places based on various factors.
The map, which is made annually by security and health risk services company, International SOS, assesses the countries on medical risks, climate change, mental health, and more.
Disruptive events such as conflict, infectious diseases, and impacts of extreme weather events, are also reflected in the ranking.
The grading system is worded slightly differently for each category of risk, but each uses a five-level scale.
For example, medical ranking ranges from ‘low’ to ‘very high,’ whereas security ranges from ‘insignificant’ to ‘extreme.’

Across all three main categories of risk, the U.K. ranked ‘low.’
However, where mental health is concerned, the U.K. scored the second highest.
Sally Llewellyn, global security director at International SOS, revealed that the study had not seen a decreased security risk for any country this year.
She noted: “Geopolitical tensions have been the most prominent trigger, with changes to risk ratings for locations such as Sudan and Lebanon, where the intensity and expansion of conflict now impact more population centres and have pushed the overall risk rating up.
“International SOS continues to support organisations operating in these locations with verified information and advice on how such risks will affect their workforce and evacuations where needed.”
But before we dive into the most dangerous countries, places that were deemed the safest in the world, from a security risk point of view, include Canada, the United States, the United Kingdom, Spain, France, Morocco, and Vietnam among others.

According to the study, Somalia, Sudan, South Sudan, and the Central African Republic have been deemed some of the most dangerous places to visit this year, from a security perspective.
Also on the list were Yemen, Libya, Iraq, Afghanistan, Syria, and Ukraine.
Countries that had a ‘high’ security risk as opposed to ‘extreme’ include: Mali, Ethiopia, Nigeria, the Democratic Republic of the Congo, Pakistan, Myanmar, Papua New Guinea, Venezuela, Haiti, and Honduras.
In regards to medical risks, there were notable changes for two countries this year.
Bolivia rose from medium to high risk, and Libya decreased from extreme to high.
Dr Katherine O’Reilly, International SOS regional medical director, noted: “Changes to medical risks are based on factors including the standard and access to healthcare facilities, availability of medicines and the prevalence of infections and diseases.
“Using data-driven tools is critical for organisations to maintain their Duty of Care responsibilities and protect their workforce, whether their employees are traveling or working domestically.”
