Rapid Diagnostic Tests for the Monkeypox Virus: A Global Health Imperative

The global health landscape is continuously evolving, with new threats emerging and existing ones re-emerging in different forms. One such re-emerging threat is the monkeypox virus, a zoonotic disease that has been causing significant concern among health authorities worldwide. The recent outbreak of monkeypox, particularly in Africa, has underscored the urgent need for effective diagnostic solutions. Companies like Fapon Biotech, Bluestain Global, Guangzhou Daan Gene Co Ltd, and Contipharma are at the forefront of this battle, developing rapid diagnostic tests that promise to revolutionize the way we detect and manage this virus.

Fapon Biotech, headquartered in Shenzhen, China, is a global leader in the in-vitro diagnostics industry. The company is dedicated to advancing global health by providing innovative diagnostic solutions. On August 14, 2024, the World Health Organization declared the monkeypox outbreak a public health emergency of international concern. In response, Fapon Biotech reaffirmed its commitment to addressing this emerging threat by providing antigen diagnostic products. Since the outbreak in 2022, Fapon has been developing and upgrading its raw materials solutions for monkeypox antigen rapid tests. These products boast high sensitivity, specificity, and no cross-reactivity with non-orthopoxviruses like the varicella-zoster virus, making them highly effective for accurate detection.

The importance of accessible and effective diagnostic solutions cannot be overstated, especially in low- and middle-income countries where healthcare infrastructure may be limited. The global circulation of the monkeypox virus in 2023 significantly increased the demand for diagnostics, highlighting the need for simplified and accessible tests outside traditional laboratory settings. The World Health Organization has specified a target product profile for decentralized use, encouraging more companies to develop point-of-care testing (POCT) products. These products are designed to be convenient and accessible for screening and diagnosis in rural areas with limited healthcare resources, ensuring that even the most vulnerable populations can benefit from early detection and treatment.

Bluestain Global, a British-Portuguese joint venture, has also made significant strides in the fight against the monkeypox virus. The company recently launched a new rapid detection test for the mpox virus, which offers unmatched speed and accuracy. This test can be administered with minimal training, making it ideal for use in clinical settings and in the field. The test provides results in 15-30 minutes, making it essential for early detection and containment of mpox outbreaks. The rapid turnaround time is crucial in preventing the spread of the virus, especially in high-risk populations and regions with limited healthcare infrastructure.

The Bluestain MPox test is engineered with cutting-edge molecular techniques for unparalleled sensitivity and specificity. According to Professor Fernando Ferreira, Chairman of Bluestain Global, the fast and accurate results of the test empower health authorities to respond swiftly and isolate infected individuals. This capability is indispensable in breaking the chain of transmission and minimizing the virus’s impact on communities. The test also facilitates contact tracing and other containment strategies without delay, making it a vital tool in the ongoing battle against the mpox virus.

Another key player in the development of rapid diagnostic tests for the monkeypox virus is Guangzhou Daan Gene Co Ltd. The company recently received approval from the Guangdong Provincial Medical Products Administration for its new PCR-fluorescence probing product, which is used for in vitro qualitative detection of the monkeypox f3l gene in suspected cases. This testing kit can be used for skin lesion samples and throat swab samples, providing a versatile and effective solution for detecting the presence of the virus. The National Medical Products Administration approved the product for market use in response to the emergence of mpox in different countries, marking an important step in controlling the spread of the virus.

The development and approval of Guangzhou Daan Gene Co Ltd’s product highlight the importance of ongoing post-market supervision to ensure the safety and efficacy of diagnostic tools. MPox, formerly known as monkeypox, is a disease that can be transmitted from animals to humans. It is typically found in parts of central and western Africa and is characterized by fever, rash, and swollen lymph nodes. The main mode of transmission is through contact with bodily fluids, skin lesions, respiratory droplets, and contaminated objects. The ability to detect the presence of mpox in animals, such as squirrels, rats, mice, and monkeys, is crucial for preventing zoonotic transmission and controlling outbreaks.

Contipharma, based in Liège, Belgium, has also joined the fight against the monkeypox virus by launching a rapid testing kit. The company’s lamp screening kit combines the sensitivity and specificity of a PCR test with the speed of an antigen test, providing results within 20 minutes. This test does not require a laboratory visit, making it more accessible for screening in resource-limited settings. Initial evaluations in Europe have shown the performance of the lamp mpox test to be effective, and further evaluations are currently being conducted in the field with support from the Institute National de la Recherche Biomedicale in Kinshasa.

The rapid detection of the monkeypox virus is crucial in preventing further spread of the disease, especially in regions experiencing severe outbreaks. The UN reports a severe outbreak of monkeypox in the Democratic Republic of Congo since the beginning of 2024, resulting in over 14,000 cases and 51 deaths. Rapid detection helps differentiate monkeypox from other infections, such as chickenpox, measles, herpes, or syphilis, which can present with similar symptoms. Contipharma’s lamp screening kit is the result of two years of research and development, with contributions from Professor-Doctor Jean-Jacques Muyembe from the INRB, and promises to provide rapid and effective screening in the field.

Contipharma’s mission is to provide an effective response to public health issues, particularly in regions where there is a shortage of medication or price barriers. The company invests in R&D projects by biotech and medtech start-ups in Belgium and has been supplying rapid COVID-19 antigen tests both domestically and internationally since January 2021. The launch of the mpox lamp test is a testament to Contipharma’s dedication to addressing emerging health threats and providing accessible diagnostic solutions for all.

The collective efforts of companies like Fapon Biotech, Bluestain Global, Guangzhou Daan Gene Co Ltd, and Contipharma underscore the critical role of rapid diagnostic tests in the fight against the monkeypox virus. These tests not only facilitate early detection and treatment but also empower health authorities to implement effective containment strategies, thereby preventing large-scale outbreaks. As the global health community continues to grapple with the challenges posed by emerging infectious diseases, the development and deployment of rapid diagnostic tests will remain a cornerstone of public health preparedness and response.

In conclusion, the rapid diagnostic tests developed by Fapon Biotech, Bluestain Global, Guangzhou Daan Gene Co Ltd, and Contipharma represent significant advancements in the fight against the monkeypox virus. These tests offer high sensitivity and specificity, rapid turnaround times, and accessibility in resource-limited settings, making them invaluable tools for early detection and containment. As the world continues to face the threat of emerging infectious diseases, the importance of innovative diagnostic solutions cannot be overstated. By leveraging cutting-edge technology and fostering collaboration among global health partners, these companies are paving the way for a safer and healthier future.
