The pandemic of coronavirus disease (COVID-19) has been one of the greatest medical disasters in recent human history. It has uprooted the lives of many people, infected millions of people all over the world, and resulted in hundreds of thousands of deaths. One of the worrisome facts about COVID-19 is that it disproportionately affects older people and those with uncontrolled diabetes, hypertension, and cardiovascular disease.[1] In this issue of the Journal of Diabetology, we have a series of five articles dealing with COVID-19. In the first article, Unnikrishnan et al.[2] discuss the connection between diabetes and COVID-19 and talk about the precautions that people with diabetes should take.

In the second article, Chopra et al.[3] discuss the link between hypertension and cardiovascular disease and COVID-19. The issue of angiotensin-converting enzyme (ACE) inhibitors and angiotensin II receptor blocker (ARBs) in the context of COVID-19 which became a contentious issue is also discussed. The third article by Anjana et al.[4] discusses the role of hydroxychloroquine (HCQ) which suddenly shot into its prominence after it was shown that it may have a role in the treatment of COVID-19 but later it became a hotly debated issue. The fourth article deals with Vitamin D and COVID-19 which is another contentious issue and this is described in detail by Suvarna and Mohan[5] In the fifth article by Poongothai et al.,[6] the problems with conducting clinical trials during COVID-19 are discussed. These series of five articles form a very important contribution to the Journal of Diabetology.

COVID-19 has taught us many new things about the way we practice medicine. The emergence of telemedicine in treating diabetes and the virtual diabetes clinic are other offshoots of COVID-19.[7],[8] These will be discussed in subsequent issues of Journal of Diabetology.
