The COVID-19 pandemic has resulted in a major change in the practice of medicine worldwide [1]. Many obstetrician/gynecologists (OBGYNs) are now providing only essential services, such as maternity care and cancer surgery. Surgery for benign diseases has been postponed. Many international conferences and meetings have been cancelled or postponed as a result of the COVID-19 pandemic.

International conferences are useful for both junior and senior OBGYN doctors. However, the pandemic situation requires social distancing and avoidance of movement between countries. How then do we learn about medical issues and gain knowledge about the COVID-19 pandemic in other countries? Although the number of deaths and infections varies between countries, the medical challenges remain constant [2].

In this situation, information and communication technology (ICT) may be helpful. Twitter is fast and voluminous, and anyone can follow a celebrity/influencer and gather information. For example, the American Journal of Obstetrics and Gynecology uploaded a preprint of a maternal death case series to its Twitter feed [3]. This allowed dissemination of information regarding predictors of mortality, such as high C-reactive protein and decreased transcutaneous oximetry; we should, thus, be cautious in pregnant women who are afebrile and asymptomatic but have these laboratory findings.

We have informed the residents at our institution to share information from well-known scientific journals, such as New England Journal of Medicine, Lancet, Journal of the American Medical Association, British Medical Journal, American Journal of Obstetrics and Gynecology, Obstetrics and Gynecology, and BJOG: An International Journal of Obstetrics and Gynaecology on Twitter. In this way, residents can not only obtain information on COVID-19, but also benefit from discussions on the latest medical advances and learn more general information in the field.

Both in Japan and Germany, use of Twitter is quite low [4]. Both these countries had good results in controlling the number of cases of infection with COVID-19. To maintain this and further contain the epidemic, it is very important to gather the appropriate medical information early. Their methods could be beneficial to other countries if known timeously.

We believe that the use of Twitter as described will enhance the spread of medical information to OBGYN doctors and inform public health policy in other countries and regions.
