Streptococcus pneumoniae can spread through droplets in the air as with COVID-19, and S pneumoniae may enter and remain in the nose and throat. 4 The incubation period of S pneumoniae is about 1 to 3 days, after which it can invade the lungs, blood, sinuses, middle ear, or brain, potentially leading to a severe and fatal infection. "Invasive pneumococcal disease" is defined as an infection confirmed by the isolation of S pneumoniae from a normally sterile site, such as blood, cerebrospinal fluid, and pleural, joint, or peritoneal fluid. 5 Invasive pneumococcus is a notifiable disease, and it must be reported to the Taiwan CDC within 1 week. We believe that the reduction in invasive pneumococcus disease has been influenced by the current preventive strategies for COVID-19 in Taiwan.
