Severe Fever with Thrombocytopenia Syndrome (SFTS) Concerns Rise After Veterinarian’s Death in Japan
Table of Contents
The recent death of a veterinarian in Japan, shortly after treating a cat suspected of having Severe Fever with Thrombocytopenia Syndrome (SFTS), has heightened concerns about the spread of this tick-borne viral disease. The veterinarian, who practiced in Mie prefecture, exhibited symptoms consistent with SFTS. While an autopsy did not reveal a tick bite, authorities are investigating the potential transmission route.
Veterinarian’s Death Sparks SFTS Awareness
The incident has prompted the Japan Veterinary Medical Association (JVMA) to issue warnings to its members, urging them to take stringent precautions against SFTS.The JVMA, in collaboration with the National Institute of Infectious Diseases (NIID), is providing veterinarians with comprehensive guidelines on identifying infected animals, preventing tick bites, handling potentially infectious fluids, and safely disposing of deceased animals.
Did You Know? SFTS was first identified in China in 2011 and has as spread to other East Asian countries, including Japan, South Korea, Vietnam, and Taiwan.
Understanding severe Fever with Thrombocytopenia Syndrome (SFTS)
Severe Fever with Thrombocytopenia Syndrome (SFTS) is an emerging infectious disease caused by the SFTS virus (SFTSV) [[2]]. The virus, a member of the *Phenuiviridae* family [[3]], is primarily transmitted to humans through the bite of infected ticks.
symptoms and Diagnosis
The typical symptoms of SFTS include fever,fatigue,loss of appetite,vomiting,and jaundice. Patients may also present with a visible tick bite. Blood tests often reveal leukopenia (reduced white blood cells), thrombocytopenia (reduced platelets), and elevated liver enzyme levels.
Transmission and Risk Factors
SFTS virus is commonly transmitted by ticks, including the Asian long-horned tick, which acquire the virus from wild animals such as deer and boars. These ticks can attach to pets in grassy areas or directly to humans walking through bushes. Rising temperatures are expanding the distribution range of these ticks, which were previously concentrated in southern Japan.
Pro Tip: When spending time outdoors, wear long sleeves and pants, use insect repellent, and check yourself and your pets for ticks regularly.
SFTS Mortality and Classification
In 2019, the NIID classified SFTS as a new viral hemorrhagic fever due to its high mortality rate, placing it alongside diseases like Dengue and Ebola. The mortality rate for SFTS ranges from 12% to over 30%, with most fatalities resulting from multi-organ failure. Older adults are particularly vulnerable, accounting for 90% of reported cases.

| Mortality Rate | 12% – 30%+ |
| Risk Groups | Older adults, individuals with compromised immune systems |
| Geographic Distribution | China, Japan, South korea, Vietnam, Taiwan |
Evergreen Insights on SFTS
SFTS represents a growing concern in public health due to its potential for severe illness and the expanding geographic range of its tick vectors. Understanding the transmission dynamics, symptoms, and preventive measures is crucial for mitigating the risk of infection.Ongoing research focuses on developing effective treatments and vaccines to combat this emerging infectious disease [[1]].
Frequently Asked Questions About SFTS
- What is Severe Fever with Thrombocytopenia syndrome (SFTS)?
- Severe Fever with Thrombocytopenia Syndrome (SFTS) is an emerging infectious disease transmitted by ticks. It is caused by the SFTS virus (SFTSV) [[2]], and is characterized by fever, thrombocytopenia (low platelet count), and leukopenia (low white blood cell count).
- What are the symptoms of SFTS?
- Common symptoms of SFTS include fever,fatigue,loss of appetite,vomiting,and jaundice. A tick bite may also be visible. Blood tests frequently enough reveal reduced white blood cells and platelets, along with elevated liver enzyme levels.
- How is SFTS transmitted?
- SFTS is primarily transmitted through the bite of infected ticks, such as the Asian long-horned tick. These ticks can acquire the virus from wild animals like deer and boars [[3]]. Transmission can also occur through direct contact with the blood or bodily fluids of an infected person or animal.
- Where has SFTS been reported?
- SFTS was first identified in China in 2011. As then, cases have been reported in Japan, South Korea, Vietnam, and Taiwan.
- What precautions can be taken to prevent SFTS?
- Precautions against SFTS include avoiding tick-infested areas,wearing protective clothing (long sleeves and pants) when outdoors,using insect repellent containing DEET,and regularly checking for and removing ticks. Veterinarians and healthcare workers should take extra precautions when handling potentially infected animals or patients.
- what is the mortality rate associated with SFTS?
- The mortality rate for SFTS varies, ranging from 12% to over 30%. Most fatalities result from multi-organ failure.
- Is Severe Fever with Thrombocytopenia Syndrome a growing global health concern?
- Yes, Severe Fever with Thrombocytopenia Syndrome (SFTS) is considered a growing global health concern due to its emerging nature and potential for severe illness [[1]].
