Middle East Respiratory Syndrome (MERS) is a serious viral infection caused by MERS-CoV, affecting the respiratory system with symptoms like fever, cough, and shortness of breath. Diagnosis relies on detecting the MERS antibody using immunoassay reagents and anti-MERS antibody tests. While there is no cure for MERS, treatment focuses on symptom management. Early detection through MERS antibody immunodiagnostic products is key to controlling the disease.
