An interrelationship between parasitic infestation and COVID-19 is interesting. Some reports mention for possible counteracting action to COVID-19 in parasitic infestation. In a recent report, Wolday et al. noted that “Parasite co-infection is associated with a reduced risk of severe COVID-19 in African patients.” Despite COVID-19's extensive distribution, no endemic parasitic infection has yet been identified as co-infecting with COVID-19. A good example is opisthorchiasis. Regarding opisthorchiasis and COVID-19, the possible specific counteracting biological process is proposed.
Here, the authors would like to draw attention to another important parasitic infection that has never been reported for association with COVID-19. Based on our setting in Indochina, where cysticercosis is very common, the authors reappraise local data on COVID-19 case. The setting has been affected by COVID-19 since January 2020. Until present, there are more than 1.5 million COVID-19 infected cases. According to local protocol for management, routine chest X-ray investigation is done. Of interest, there has never observation on coincidence between cysticercosis and OVID-19. In this setting, the cysticercosis is prevalent. The prevalence of detection of cysticercosis in routine chest X-ray investigation is 0.1%. Based on the data on the epidemiology of cysticercosis in this setting, it is likely that there should be a coincidence of COVID-19 and cysticercosis detected from chest X-ray, however, there is no observation on coincidence.
This leads to an interesting question whether cysticercosis has a pathophysiological process that can protect against COVID-19. A possible mechanism might be associated with CD4 + Foxp3+. Excretory secretory antigens from cysticercus can increase the CD4 + Foxp3 + and CD8 + Foxp3 + T-cell frequencies. Stimulation of CD4 + Foxp3 + is proposed as a possible process for the treatment of COVID-19.
