The Effect of Nanogold-Nanosilver to Increase the Immunity of People Affected by COVID-19 with Hypertension Comorbidities

The SARS‐CoV‐ 2/Covid-19 Coronavirus is currently endemic throughout the world. The comorbidities of Covid-19 with the highest percentage reaching 50.5% are hypertension. Hypertension included in Non-Communicable Diseases (NCD) is generally chronic. It can reduce the sufferer’s immune system gradually and is very susceptible to infections, including those caused by viral infections, one of which is the SARS-CoV-2 virus or commonly called COVID-19. Therefore, patients with NCD, especially hypertension, are encouraged to increase immunity and body immunity to avoid virus infection. Currently, nanoparticles, especially Nanogold and Nanosilver, are taking place very rapidly in the health sector because gold and silver nanoparticles have various benefits such as antioxidants, antivirals, and antibacterials. After being proven effective in dealing with leprosy patients in Surabaya, especially in terms of increasing immunity. Now Nanogold-Nanosilver was developed with the hope to help relieve Covid-19 sufferers through increasing the body’s immune system because if the body’s immune system decreases, the virus will quickly enter the body. In this study, Nanogold and Nanosilver were developed into a health water drink that volunteers can drink every day. Volunteers are people affected by Covid-19 in the Karanganyar area of Surabaya. This study uses a one-group pretest-posttest design. The data collection is carried out through direct observation and interviews with people affected by Covid-19 regularly every week. Then the data analysed using a paired T-test on the SPSS application. And obtained a P-value of 0.000, which means that there is an effect of nanogold-nanosilver for increase body immunity.
