COVID toes is a phenomenon which started to be reported in Italy and Spain at the outset of the winter season within the initial wave of the novel coronavirus outbreak in 2020. The stories were getting a high occurrence of chilblains in the feet in people with COVID-19. The news media locked onto these accounts and a lot of attention was given to them. A great deal of interest continues to be produced from the general public and health care professionals in the entire phenomenon of these COVID toes.

There are a variety of pathophysiological functions connected to COVID-19, such as complications with the blood flow, the cytokine storm and inflamation related processes that may impact the blood circulation in the toes that predispose the foot or toes to having chilblains. Chilblains are a poor response of the small blood vessels to alterations in temperature. Should the tiny arteries do not react adequately, waste material accumulate in the skin bringing about an inflammatory process that is the chilblain. It isn't difficult to see how COVID-19 could increase the possibility of having a chilblain. Several early histological studies from biopsies of the chilblains in those that have COVID-19 did show that there were portions of the infection present in the tissues. However, some other studies have showed that there weren’t any, therefore it has begun to become really baffling in regards to what the connection involving the 2 entities actually are.

The problem is that with the passing of time and further investigation we have an escalating volume of research that there's simply no relationship involving chilblains and COVID-19 and the high occurrence is merely a coincidence. There exists one study from the Nordic countries that there has been no rise in the prevalence of chilblains in those countries. Several other new investigations by way of biopsies as well as post-mortem autopsy have found no COVID components associated with the chilblains. You can find speculation how the presumed rise in the occurrence in many nations would be a problem with the lifestyle variations due to the lockdown through the outbreak and they aren't in reality part of the pathophysiological process of the infection. These lifestyle changes while in the lockdown can consist of being a lot more inactive, perhaps the much less wearing of shoes, becoming more in contact with air-conditioning along with the constant warmness in the house. These types of changes in lifestyle during lockdown appears to be more in countries like Italy and Spain and the changes could not have been so much in the Nordic countries. In Nordic nations they may simply be much better at managing the issues around temperature fluctuations that are regarded as a risk factor in chilblains. This can simply account for the various prevalence in those two locations.

An instalment of the podiatry live stream, PodChatLive had been on this very theme. The livestream hosts chatted with a foot doctor in South Africa, Nadia Dembskey who's about to start a Doctor of Philosophy on the topic. Just about all of the aforementioned concerns were discussed, and they still have not ended up reconciled. Given all of the disagreeing literature as well as the inconsistent ideas that there are on the topic, it may possibly be some time before the science extends to solve this.
