One in every five adult Rohingya refugees in Cox’s Bazar is living with Hepatitis C, a trend echoed among thousands of newly arrived refugees. As many as 20 to 22 percent of the nearly 150,000 Rohingyas who entered Bangladesh in recent months tested positive for Hepatitis C, said Sarwar Jahan, assistant medical coordinator at RRRC. His Hepatitis C diagnosis in 2025 finally explained years of unexplained exhaustion and episodes where his vision suddenly darkened. Patients typically complain only of fatigue, poor appetite or abdominal pain but many arrive without obvious symptoms as hepatitis C often remains symptomless for years, according to Sumaiya Yousuf, a medical doctor with the MSF Hepatitis C Project. If untreated, Hepatitis C can progress to liver cirrhosis or liver cancer.
