Just two months before the Olympic Games, set to kick off in Japan on July 23, the US State Department has issued a travel advisory warning Americans away from the country as coronavirus cases escalate. The State Department issued its highest possible caution, “Level 4: Do Not Travel”, based on recommendations from the US Centres for Disease Control and Prevention. The same level of warning was issued for Sri Lanka. “Travellers should avoid all travel to Japan,” the CDC’s warning posted on Monday reads. “Because of the current situation in Japan, even fully vaccinated travellers may be at risk for getting and spreading Covid-19 variants and should avoid all travel to Japan.” The US had issued Level 4 warnings for 80 per cent of the countries in the world, CNET reported on Monday, leaving Japan off the list. However the uptick in cases spurred the State Department to add that nation Monday. The United States Olympic and Paralympic Committee did not immediately respond to a request for comment, CNET noted. Japan lifted a state of emergency in March, and since then Covid-19 cases have increased. A shortage of medical professionals and a lack of syringes have led just 2 per cent of Japanese citizens to be vaccinated with at least one shot, US television network CNN reported. The country has mobilised military doctors and nurses to give shots to elderly people in Tokyo and Osaka as the government tries to stem the tide and accelerate the vaccine roll-out, Associated Press reported on Monday. China’s Xi Jinping pledges support for Tokyo Olympics as Japan extends coronavirus emergency It’s not clear whether that will be enough to keep the Games going and safe enough for athletes and spectators to participate and attend, CNN said. Pressure is mounting to cancel the Games, some of it coming from medical professionals such as the Tokyo Medical Practitioners Association, a 6,000-member doctors group, which recently wrote a letter calling for a cancellation. In addition, a petition supporting cancellation gathered 350,000 signatures in nine days and was submitted to organisers, CNN said.
