Citizens traveling to Japan for work or leisure should be aware that Tokyo, Saitama, and other areas in the Kanto region are currently experiencing an outbreak of 'Apple Disease', medically known as infectious erythema. The number of reported cases has reached new highs since 1999. The disease is spread through a virus and can cause cold-like symptoms such as fever and cough, mainly affecting children. Pregnant women are at risk of miscarriage if infected, so precautions are necessary.
Erythema is a rash-like illness marked by a characteristic red rash on the cheeks, resembling an apple, hence the name 'Apple Disease'. According to reports from TBS and other sources, there has been a sudden increase in cases since November. During the week leading up to December 1st, 796 cases of 'infectious erythema' were reported by 264 medical institutions in Tokyo, setting a new record since tallying began in 1999. The number of cases has exceeded the alert level for three consecutive weeks. This is the first time since 2018 that patient numbers have surpassed the alert level.
Alcohol-based sanitizers ineffective against the virus, increasing prevention challenges
This infectious erythema is mainly spread through coughing and sneezing. Notably, regular alcohol-based sanitizers are ineffective against this virus, complicating prevention efforts. The Tokyo Metropolitan Government advises the public to wash hands frequently with soap and to wear masks in crowded places to prevent infection.
If someone contracts 'Apple Disease', the incubation period typically ranges from several days to two weeks. After onset, symptoms such as fever and cough may appear, eventually leading to red rashes on the cheeks and arms. Some people may also experience joint pain. The disease predominantly affects children, but for pregnant women, it can cause severe anemia in the fetus, leading to miscarriage or stillbirth. As the virus is difficult to protect against, the most prudent measure is to avoid affected areas during an outbreak.
