The World Health Organization reported 19 confirmed cases of Middle East respiratory syndrome coronavirus (MERS-CoV) worldwide through Dec. 21, 2025, including four deaths. This confirms that MERS-CoV “continues to represent a persistent threat” in areas where the virus circulates among dromedary camels, though the overall global and regional risk assessment remains moderate.
Seventeen of the 19 cases were reported in Saudi Arabia, the main focal point of MERS-CoV transmission since its identification in 2012. France reported two cases linked to recent travel to the Arabian Peninsula,highlighting the ongoing risk for travelers.
MERS-CoV is a zoonotic coronavirus primarily transmitted from dromedary camels to humans. While most infections are animal-to-human, limited human-to-human spread has occured, notably in healthcare settings with insufficient infection prevention and control. The virus has an estimated case fatality rate of around 37%, varying based on individual factors and access to care.
Despite the relatively low case numbers in 2025, WHO stresses the potential for future infections and emphasizes the need for continued epidemiological surveillance and timely public health responses, especially in affected countries. key recommendations include early detection, appropriate patient management, and strengthened infection control in healthcare facilities.
This update coincides with WHO’s shift from crisis response to sustained management of coronavirus threats. A new global strategy through 2030 integrates COVID-19, MERS, and potential future coronaviruses into long-term national health programs, drawing on lessons from the COVID-19 pandemic and ongoing MERS research. WHO encourages countries to align their actions with this framework to improve resilience and readiness for future respiratory disease challenges, recognizing coronaviruses as significant infectious threats best managed within existing respiratory disease programs, including influenza.
WHO reports 19 MERS-CoV Cases, 2025 Strategy Evolves

the World Health Organization (WHO) recently reported 19 confirmed cases of Middle East Respiratory Syndrome Coronavirus (MERS-CoV) globally. This update, released on December 26, 2025, highlights the ongoing, though relatively contained, threat posed by this zoonotic virus. The cases were reported across several countries, primarily in the Arabian Peninsula.
Understanding MERS-CoV
MERS-CoV is a viral respiratory illness first identified in Saudi Arabia in 2012. It’s caused by the MERS coronavirus, a relative of the virus that causes SARS (Severe Acute Respiratory Syndrome).The virus originates in camels and is transmitted to humans through close contact with these animals. Human-to-human transmission is absolutely possible, but generally requires close contact with an infected person.
Current Situation & Case Breakdown
The 19 cases reported represent activity from November and December 2025. The WHO details that the majority of these cases are primary infections, meaning the individuals contracted the virus directly from camels. A smaller number represent secondary transmission – spread from an infected person to another. The WHO continues to monitor the situation closely, tracking the geographic distribution of cases and analyzing viral genetic sequences.
Symptoms of MERS-CoV
Symptoms of MERS-CoV are similar to those of other respiratory illnesses, including:
- Fever
- Cough
- Shortness of breath
- Pneumonia
- In some cases, severe acute respiratory distress syndrome (ARDS)
The severity of the illness can range from mild to life-threatening. Individuals with underlying medical conditions, such as chronic lung disease or diabetes, are at higher risk of developing severe disease.
WHO’s Evolving strategy for 2025
The WHO’s strategy for managing MERS-CoV has evolved over the years. In 2025, the focus remains on:
- Surveillance: Strengthening global surveillance systems to detect and report cases promptly.
- Risk Communication: Providing clear and accurate details to the public about the virus, its transmission, and prevention measures.
- Infection Prevention and Control: Implementing robust infection prevention and control measures in healthcare settings.
- Research: Supporting research to better understand the virus, develop effective treatments, and potentially create a vaccine.
- Camel Management: Working with countries in the Arabian Peninsula to improve camel management practices and reduce the risk of transmission to humans.
Prevention Measures
Individuals can take several steps to protect themselves from MERS-CoV:
- Avoid close contact with camels, especially sick ones.
- Practice good hygiene, including frequent handwashing with soap and water.
- Avoid touching yoru eyes, nose, and mouth.
- Cover your mouth and nose when coughing or sneezing.
- If you experience symptoms of respiratory illness, seek medical attention promptly.
Key Takeaways
- MERS-CoV remains a public health concern, with 19 cases reported globally recently.
- The virus originates in camels and can spread to humans through close contact.
- Symptoms are similar to other respiratory illnesses,but can be severe.
- The WHO’s strategy focuses on surveillance, risk communication, infection control, research, and camel management.
- Preventive measures include avoiding contact with camels and practicing good hygiene.
