In a significant development, Japan's National Institute of Infectious Diseases (NIID) has confirmed the first domestic case of human-to-human transmission of severe fever with thrombocytopenia syndrome (SFTS), a tick-borne viral disease. This marks a pivotal moment in understanding the spread of SFTS within the country.
The transmission occurred between a patient in his 90s and a male doctor in his 20s. The elderly patient was diagnosed with SFTS after visiting the emergency room last April due to deteriorating health. During his treatment, the doctor performed various medical procedures, including the removal of the patient's catheter post-mortem. While the doctor wore a face mask and gloves, he did not use goggles during these procedures.
Nine days following the patient's death, the doctor began exhibiting symptoms of fever and headache. Medical examinations confirmed that he had contracted SFTS. Genetic analysis revealed that the viruses from both the patient and the doctor were identical, conclusively demonstrating human-to-human transmission.
This breakthrough highlights the need for enhanced protective measures in medical settings, especially when dealing with infectious diseases like SFTS. The NIID is now likely to reassess and update guidelines to prevent future transmissions, ensuring the safety of healthcare professionals and patients alike.
The confirmation of SFTS transmission underscores the dynamic nature of viral diseases and the importance of vigilance in public health practices. As Japan navigates this new challenge, the global community watches closely, recognizing the broader implications for infectious disease management worldwide.
