Health officials are sounding the alarm over a sharp increase in potentially severe Mycoplasma pneumoniae infections across Japan. In the week ending on 22 September, an average of 1.48 cases per medical institution were reported nationwide, the highest weekly rate in a decade. Fukui prefecture has the highest infection rate, followed by Tokyo, Gifu, Ibaraki, Osaka, and Hiroshima. The respiratory illness spreads through airborne droplets and can cause fever, cough, fatigue, and headache.





The health ministry warns that patients have become infected at school and home in many cases. It urges people to wash their hands with soap and wear face masks if they cough.


 
I wonder what makes something that has been dormant for four to five years suddenly flare up again? People's resistance to said strain of bacteria has declined enough that it's easy to infect again?
The world of vira and bacteria is a strange and interesting one.
 
The article hints a bit at that phenomenon: during the COVID-19 pandemic, most countries implemented strict measures of infection control and restricted social contacts, thereby keeping all sorts of viruses in check. I just read that cases of syphilis are spiking here, too.



 
Cases of Mycoplasma pneumonia continue to rise in Japan, with no signs of abating. According to the National Institute of Infectious Diseases, the average number of patients per designated medical institution reached a record high during the week ending 6 October. This marks six consecutive weeks of increasing cases.


Mycoplasma pneumonia is a respiratory infection caused by a bacterium. It spreads through the air when an infected person coughs or sneezes. Symptoms include fever, fatigue, headache, and a persistent cough lasting for weeks. While most people recover on their own, some may develop severe pneumonia requiring hospitalization. In rare cases, complications like encephalitis can occur. Antibiotics can help treat Mycoplasma pneumonia. Because the incubation period is two to three weeks, symptoms may appear long after exposure, even when you think the risk has passed.



Masks are back here in Japan. Or perhaps they've never been gone.
