The virus spreads through urban and sylvatic cycles via vectors such as <em>Culicoides</em> midges and <em>Culex</em> mosquitos, with humans and some vertebrates serving as amplifying hosts. The manuscript aims to analyze the transmission dynamics, clinical manifestations, diagnostic approaches, and potential preventive strategies for OROV. OROV is becoming an increasing health concern due to its global expansion and potential for serious consequences. Its growing threat, especially in light of the possibility of congenital abnormalities, is highlighted by the first recorded deaths in 2024 and the verification of vertical transmission. Clinical symptoms overlap greatly with other arboviruses, limiting early diagnosis; nonetheless, molecular approaches such as RT-PCR are crucial for identification. The current therapy is restricted to symptom control, highlighting the critical need for effective vaccinations. Live attenuated vaccination candidates and innovative techniques based on reverse genetics systems are both promising discoveries. However, the genetic variety of OROV strains poses obstacles to obtaining broad protection.

This review describes clinical cases and preclinical studies in which phage therapy has been effective in both human and veterinary medicine, and in an agricultural context. In addition, critical challenges, such as the narrow host range of bacteriophages, the possibility of bacterial resistance, and regulatory constraints on the widespread use of phage therapy, are addressed. Future directions include optimizing phage therapy through strategies ranging from phage cocktails to broadening phage host range through genetic modification, and using phages as vaccines or biocontrol agents. In the future, if phage can be efficiently delivered, maintained in a stable state, and phage–antibiotic synergy can be achieved, phage therapy will offer much needed treatment options. However, the successful implementation of phage therapy within the current standards of practice will also require the considerable development of regulatory infrastructure and greater public acceptance.
