Mongolia is one of the world’s most sparsely populated countries yet is home to the highest infection rates of hepatitis B and D coinfection worldwide1. The World Health Organization (WHO) estimates that about 5-10% of the nearly 300 million global hepatitis B patients are co-infected with hepatitis D. Hepatitis D is the most severe form of viral hepatitis, and greatly increases the risk of cirrhosis, scarring of the liver, and liver cancer; with seven out of 10 patients progressing within 10 years 4. In Mongolia, 70% of hepatitis B patients are coinfected with hepatitis D, and the country is known for having the highest rates of liver cancer on the planet2,3. These statistics are startling and highlight a public health crisis for Mongolia, where most families have at least one family member affected 2.
How are people getting infected?
Historically, healthcare-related exposures are suspected to be the biggest risk for contracting hepatitis in Mongolia. Despite the 1993 national policy was set to regulate the multi-use of single-use syringes in healthcare settings, effective sterilization practices, and medical staff training, proper inspections remain an ongoing issue. Healthcare workers themselves are also at risk, with requirements for hepatitis B vaccination set by the Ministry of Health recently in 20145. Although routine infant vaccination for hepatitis B began in 19916, older populations remain at risk or are susceptible to exposures.
For a nation so widely affected by liver disease, as of 2015, skilled physicians and liver transplant experts are sparse – with only one reported team performing transplants in Ulaanbaatar, the capital city1. Fibroscan, CT scans, and liver biopsies; routine screening tools for liver disease and liver cancer, have only been introduced in recent years, and are still not routinely used for liver cancer screening as recommended by WHO7. This lack of surveillance leaves most patients to endure late diagnoses. Due to the rural landscape, where nearly 30% of the population lives below the poverty line10 and historically nomadic lifestyle accessing care is a challenge. Access to treatment for hepatitis B is additionally a challenge, and traditional medicines might be utilized. Pegylated interferon, the only current and somewhat effective treatment for hepatitis B and D coinfection, was registered about 10 years ago in Mongolia and is still not covered by its national healthcare system, making it too expensive for most low and middle-income families8. With the help of partnerships, the government has integrated funding for palliative care for liver cancer patients, with most facilities centralized around the capital city7. With a failing insurance system and little government prioritization for prevention and treatment, many are calling on the World Health Organization (WHO), pharmaceutical companies and NGOs to step in to curb the crisis9.
Mongolia’s crisis has not been left unaddressed. Over the last 10 years, Mongolia’s government has prioritized combatting hepatitis, developing its first viral hepatitis national strategy in 2010, and focusing on prevention, affordable treatment, and public awareness programs. Admirably, coverage under the national insurance plan for antivirals began in 2016, greatly subsidizing the cost of hepatitis B treatment11. These efforts did not go unnoticed, and in 2018, WHO praised Mongolia’s efforts in moving towards the elimination of hepatitis B and C, recognizing its successes in its national program, “Whole-Liver Mongolia”. Another program, “Hepatitis Free Mongolia”, an initiative of the Flagstaff International Relief Effort (FIRE), Flagstaff Rotary Club, Rotary Club of Ulaanbaatar and the WHO, offers free hepatitis education, screening, vaccination and care for those infected. The project also trains healthcare providers and offers free exams, diagnostic services and patient counseling; a vital service for many who may not be able to access or afford these services otherwise. Since 2011, the project, along with FIRE’s Love the Liver program have tested nearly 9,000 people for hepatitis B, screened 6,000 for liver cancer and performed over 3,000 specialist exams, and, in a country of only 3 million people, has made a meaningful impact. The effort is also unofficially supported by Mongolia’s Ministry of Health, who is continually investing in efforts to curb the burden of hepatitis.
