Copper (Cu) has a strong impact on the function of the immune system through several different pathways. These impacts include helping the function of monocytes, neutrophils, and macrophages, and enhancing Natural Killer cells’ activities. Cu also has a role in antimicrobial properties and inflammatory response. It is also important for IL-2 production and response, which is a component of adaptive immune cells. Additionally, Cu has multiple roles in both proliferation and differentiation of T cells and is involved in the production of antibodies. Cu deficiency can even lead to "increased viral virulence"1. Copper has a long history of use in medicine, and has continued to be used for purification of water, including use in hospitals to prevent legionnaires disease. The CDC pre released information on a study completed in March 2020 on the lifespan of COVID-19 on different surfaces which included its lifespan on copper, where it was completely dead within 4 hours. In addition, "Several reports demonstrated that Cu deficiency weakens the human immune response" 2. Given the multiple avenues of impact, it has been suggested that Cu supplementation, within recommended levels, be given to individuals who are low in Cu to help them fight off COVID-19. It is also possible that Cu supplementation, within recommended levels, may help prevent COVID-19 infection, or help individuals who are not low in Cu to fight off COVID-19 infection. However, dosage would have to be carefully managed, as excess levels of Cu can lead to both neurodegenerative and neurodevelopmental diseases. Show less

Myiasis is a parasitic infestation of the body of a mammal caused by Cordylobia Anthropophaga (Tumbu fly) larvae. The infestation is prevalent in Sub-Saharan Africa, South-East Mexico and Central America. It is usually seen among rural dwellers and has no age or sex predilection. We report a case of Tumbu fly myiasis seen in a 7month-old male living in Port Harcourt, Nigeria who was erroneously thought to have bullous impetigo. Show less

Introduction Vaccination against SARS CoV-2 started on March 2020 in Iran and people with multiple sclerosis (pwMS) have a priority to be vaccinated in line of other high-risk population. Up to now, BBIBP-CorV (Sinopharm) is the main vaccine which have been used in Iranian population, and in high risk population such as pwMS. Method In this survey, the safety and possible side effects of this vaccine after the first or/and second doses in 520 pwMS have been assessed from July to August 2021. MS Patients who have received one or two doses of Sinopharm vaccine were evaluated. Results Around 44% of pwMS who received Sinopharm reported few minor side effects, whereas its side effect have been reported in 60% of patients who received the second dose. All side effects have begun within the first 24 hours and subsided between 48-96 hours afterward. No serious side effects or mortality have been reported. There was no correlation between the side effects and age, the disability status, and the type of first or second line DMDs (disease modifying drugs). Only some side effects were significantly higher in the progressive form of the disease. Conclusion MS patients can receive Sinopharm vaccine safely and the minor side effects should not scare them.
