Cases of a lethal tick-borne virus in Japan are reportedly set to start passing the 100-people-per-year mark for the 1st time since record keeping on the condition began in 2013.
The National Institute of Infectious Diseases announced on [19 Nov 2019] that the 2019 total of 96 people affected with Huaiyangshan banyangvirus [severe fever with thrombocytopenia syndrome], also known as the SFTS virus, had surpassed the previous high of 90 in 2017. Additionally, the mortality rate is high, and due to the risk of infection being passed on by pets, the institute is warning people to be cautious. [There is a unique case of a cat transmitting SFTS virus to a veterinarian and veterinary nurse in Japan (see Severe fever w/ thrombocytopenia synd. - East Asia (02): Japan (MZ) http://promedmail.org/post/20181211.6204927). The usual transmission is via ticks. - ProMED Mod.TY]
The virus that causes SFTS was discovered by a group of Chinese researchers in 2011. It lies dormant in the body for around 6 days to 2 weeks, when it then shows symptoms including a fever, diarrhoea and bloody bowel discharges. Mortality rates of 30% have been reported. Only symptomatic treatment is available for those suffering from the virus, and there is no vaccine.
The institute has been seeking reports from medical institutions across the country regarding all patients since 2013, and an upward trend has been visible since the 1st set of reports showed 40 patients in the initiative's 1st year.
It is believed that there has not been an increase in infections, but rather that as a newly understood disease it has gradually become more easily recognized by medical professionals.
As of the end of October , an overall total of 491 patients had been diagnosed with the condition [since 1st diagnosed in the country in 2013], and at the time those reports were filed 70 of [the patients] had died. It is possible that the number of the deceased has increased since that time. SFTS is particularly dangerous for elderly people, with 90% of recorded cases among those aged 60 and over.
The virus is carried by wild animals including deer and boars; if a tick (such as the Asian longhorned tick) sucks the blood of an infected animal and then later bites into another one, it passes on the virus. While it is important to be vigilant when out in hills and fields, there is also a danger of pets transmitting the disease to their owners at home after going outside.
Masayuki Saijo, head of the institute's Department of Virology 1, said, "When your pet is feeling unwell, wear protective items including thick gloves, and try not let them bite you." [Byline: Go Kumagai]
[SFTS virus apparently has become established in Japan. There were cases every year from 2013 to present, but more cases occurred in 2017 and 2018. Cases were widely disbursed geographically in 2018, with 24 prefectures reporting infected individuals. The best way to avoid infection would be to avoid tick bites.
SFTS is a serious disease and of significant public health concern. Although SFTS virus infections may be serious, there is evidence for subclinical or mild infections as well, so the previous numbers may be an underestimate of the total number of infections. There is also some evidence for person-to-person direct transmission of the virus, but that appears to be a rare event. The virus is doubtless endemic in several countries in Asia, and cases have occurred previously in Japan. Apparently, there are 2 previously reported affected individuals who acquired their infections directly from an SFTS virus-infected cat. No mention was made of tick transmission in that instance. The possible route of transmission from the cat to the veterinarian and veterinary nurse via exposure to blood or other bodily fluids is not mentioned (see Severe fever w/ thrombocytopenia synd. - East Asia (02): Japan (MZ) http://promedmail.org/post/20181211.6204927).

Tokyo, Oct 25, 2019 (AFP) - Four people were killed and another person was missing in landslides and floods on Friday, local officials and news reports said, as Japan was hit by heavy rains just two weeks after a deadly typhoon barrelled through the country. A woman in her 60s was sent to hospital and another woman in her 40s was unaccounted for after landslides struck two houses in Chiba, southeast of Tokyo, said a local disaster management official. "She was later confirmed dead in hospital," the official told AFP. A separate landslide destroyed another house in Chiba, killing a man, public broadcaster NHK said, adding he appeared to be a person who had earlier been reported missing.
Elsewhere in Chiba prefecture, two elderly men died in separate incidents, one in a submerged car, Kyodo news agency reported. The Japan Meteorological Agency issued warnings of heavy rains, landslides and floods in a swathe of areas including eastern and central Japan. "As risks of disasters have already increased, please be extremely vigilant about landslides, rise in river water volumes and floods as rains will continue," the JMA warned on its Twitter account. Non-mandatory evacuation orders were issued to more than 390,000 residents in the Fukushima region and 5,000 people in Chiba, NHK reported. Local authorities in Minamisoma, eastern Fukushima, announced they planned to discharge water from a dam that had reached maximum capacity Friday night, raising fears of flooding in populated downstream areas.
Footage showed cars splashing through roads partly inundated with water, as several swollen rivers flooded in eastern Japan. Some 4,700 houses in the region were without power by Friday evening, while some train services were suspended, officials said. Japan was hit by Typhoon Hagibis about two weeks ago, with the death toll from the violent storm now standing at more than 80. Residents still picking up the pieces after that storm expressed frustrations over reconstruction delays and their fear of another disaster. "I'm a bit worried that if an evacuation order is issued, we will have to leave here," a woman in Nagano in central Japan who was cleaning up mud told NHK. Many of the river banks and levees that were breached during Hagibis have not yet been repaired.

Tokyo, Oct 15, 2019 (AFP) - Rescuers in Japan were working around the clock Tuesday in an increasingly desperate search for survivors of a powerful weekend typhoon that killed nearly 70 people and caused widespread destruction. Hagibis slammed into Japan on Saturday night, unleashing fierce winds and unprecedented rain that triggered landslides and caused dozens of rivers to burst their banks. By Tuesday afternoon, local media put the toll at nearly 70, with around a dozen people missing. The government's tally was lower, but it said it was still updating information. Prime Minister Shinzo Abe said there was no plan to slow rescue operations, with around 110,000 police, coast guard, firefighters and military troops involved. "Currently in damaged areas rescue work and searches for the missing are continuing around the clock," Abe told parliament. "Where rivers flooded, work is ongoing to fix spots where banks broke, and water is being pumped out where floods occurred," he added. The prime minister's office said more than 3,000 people have been rescued in the wake of the disaster, which affected 36 of the country's 47 prefectures. The defence ministry has called up several hundred reserve troops in addition to active duty soldiers for the first time since the 2011 earthquake and tsunami.
- Rain prompts new warnings - Government officials warned that more rain was expected throughout the day Tuesday in several parts of the country affected by the typhoon. "We ask people not to drop their guard and to remain fully alert," chief cabinet secretary Yoshihide Suga. told reporters. Hagibis crashed into land packing gusts up to 216 kilometres (134 miles) per hour, but it was the storm's heavy rain that caused the most damage. At least 176 rivers burst their banks, including in central Nagano, where a levee breach sent water from the Chikuma river gushing into residential neighbourhoods and submerging bullet trains in a depot up to their windows. Deaths were reported across many prefectures and included a man whose apartment was flooded, a municipal worker whose car was caught in rising waters and at least seven crew aboard a cargo ship that sank in Tokyo bay on Saturday night. By Tuesday morning, some 34,000 households were still without power, and 133,000 homes had no water. Tens of thousands of people spent Monday night in government shelters, with many unsure when they would be able to return home. "My frightened daughter can't stop shaking. We want to go home quickly," Rie Nishioka, 39, told Kyodo News agency in Miyagi prefecture.
- Government pledges aid - The government pledged financial support to affected regions without specifying how much aid it would set aside. "Support for the victims of the disaster is an urgent task," Abe said. "There are concerns that the impact on daily life and economic activities may be long-lasting." Another area affected by the storm was Fukushima, where several bags containing soil and plants collected during nuclear decontamination efforts were washed away. "Ten bags out of 2,667 were swept into a river during the typhoon, but six of them were recovered yesterday," environment ministry official Keisuke Takagi told AFP, adding that the remaining four bags had been found and would be collected soon. "Residents must be worried about the environment, but there are no reports that the bags were broken, so there will be nothing to worry about once they have been recovered safely," he said. Hagibis caused transport chaos over a holiday weekend in Japan, grounding flights and halting train services. By Tuesday, things were largely back to normal, though some flights were cancelled and train services partially disrupted where tracks or train stock were damaged by the storm. The typhoon also caused disruption to sporting events, delaying Japanese Grand Prix qualifiers and forcing Rugby World Cup organisers to cancel three matches. A crunch fixture pitting the hosts against Scotland went ahead on Sunday night, with Japan winning its first-ever quarter final spot.

Tokyo, Oct 14, 2019 (AFP) - Tens of thousands of rescue workers in Japan battled on Monday to find survivors of a powerful typhoon that killed at least 43 people, as fresh rain threatened to hamper efforts. Typhoon Hagibis crashed into the country on Saturday night, unleashing high winds and torrential rain across 36 of the country's 47 prefectures, and triggering landslides and catastrophic flooding. "Even now, many people are still unaccounted for in the disaster-hit area," Prime Minister Shinzo Abe told an emergency disaster meeting on Monday. "Units are trying their best to search for and rescue them, working day and night," Abe said.
But even as rescuers, including troops, combed through debris, the country's weather agency forecast rain in central and eastern Japan that it warned could cause further flooding and new landslides. "I would like to ask people to stay fully vigilant and continue watching for landslides and river flooding," Chief Cabinet Secretary Yoshihide Suga told a news conference. In Nagano, one of the worst-hit regions, rain was already falling and was expect to intensify. "We are concerned about the impact of the latest rain on rescue and recovery efforts," local official Hiroki Yamaguchi told AFP. "We will continue operations while watching out for secondary disasters due to the current rain."
- 43 dead, 16 missing: NHK - By late Monday afternoon, national broadcaster NHK said the toll had risen to 43 dead, with 16 others missing and over 200 people injured. The government gave lower figures but was continuing to update its information. The dead included a municipal worker whose car was overcome by floodwaters and at least seven crew from a cargo ship that sank in Tokyo Bay on Saturday night, a coast guard spokesman said. Four others, from China, Myanmar and Vietnam, were rescued when the boat sank and the coast guard was still searching for a last crew member. While Hagibis, one of the most powerful storms to hit the Tokyo area in decades, packed wind gusts of up to 216 kilometres (134 miles) per hour, it was the heavy rains that caused most damage.
A total of 142 rivers flooded, mainly in eastern and northern Japan, with river banks collapsing in two dozen places, local media said. In central Nagano, a levee breach sent water from the Chikuma river gushing into residential neighbourhoods, flooding homes up to the second floor. As water slowly receded Monday, television footage showed patients being transferred by ambulance from a Nagano hospital where some 200 people had been cut off by flooding. Elsewhere, rescuers used helicopters to winch survivors from roofs and balconies, or steered boats through muddy waters to reach those trapped.
- Japan dedicates rugby win to victims - By Monday afternoon, some 75,900 households remained without power, with 120,000 experiencing water outages. The disaster left tens of thousands of people in shelters, with many unsure when they would be able to return home. "Everything from my house was washed away before my eyes, I wasn't sure if it was a dream or real," a woman in Nagano told NHK. "I feel lucky I'm still alive." The storm brought travel chaos over the holiday weekend, grounding flights and halting commuter and bullet train services.
By Monday, most subway trains had resumed service, along with many bullet train lines, and flights had also restarted. The storm also brought havoc to the sporting world, forcing the delay of Japanese Grand Prix qualifiers and the cancellation of three Rugby World Cup matches. But a crucial decider pitting Japan against Scotland went ahead, with the hosts dedicating their stunning 28-21 win to the victims of the disaster. "To everyone that's suffering from the typhoon, this game was for you guys," said Japan captain Michael Leitch.

Tokyo, Sept 22, 2019 (AFP) - Typhoon Tapah approached southwestern Japan Sunday, with heavy rain and strong winds grounding hundreds of regional flights. Tapah, with gusts up to 162 kilometres (100 miles) per hour, was expected to draw near Nagasaki prefecture overnight, according to the Japan Meteorological Agency.
It was on course to travel through the channel between Japan and the Korean Peninsula before moving toward northern Japan on Monday, when it is expected to weaken and be downgraded, the agency said. The storm prompted cancellations of more than 400 domestic flights, according to national broadcaster NHK. "Serious caution is warranted for violent winds, high waves and landslides," said Japan's Fire and Disaster Management Agency in a statement.
So far the typhoon has caused 21 minor injuries, mostly in a southern island region of Okinawa that was hit by the storm earlier. Evacuation advisories have been issued to more than 2,000 regional residents, according to the disaster management agency. Tapah follows on the trail of Typhoon Faxai, which barrelled through Tokyo earlier this month, packing record winds that brought down power lines, caused travel chaos and disrupted Rugby World Cup preparations. It resulted in a lengthy blackout on the outskirts of Tokyo that left tens of thousands of people without power for more than a week.
