Can bleach actually cure COVID19 ?

We have fact checked this claim earlier and rated it as False. You can read it here.

As per World Health Organization (WHO), “bleach DOES NOT prevent or cure COVID-19 and can be extremely dangerous.”

The Health Desk, a COVID-19 resource for journalists powered by public health experts, also says that “Chlorine dioxide has not been verified by the medical and scientific community as a cure for COVID-19 or other diseases, and its use can be dangerous to human health.”

The US Food and Drug Administration (FDA) on 2020 had issued a warning to people who are selling Chlorine Dioxide as a COVID-19 preventive or cure. As per FDA, “Chlorine dioxide products have not been shown to be safe and effective for any use, including COVID-19”. 

The US Centers for Disease Control and Prevention (CDC) says direct exposure in larger quantities of Chlorine Dioxide can cause “damage to the substances in blood that carry oxygen throughout the body.”

A clinical trial for the use of Oral Chlorine Dioxide in the Treatment of COVID 19 has been registered in US. It was an observational study done on 20 candidates. The researchers believe that the results are positive but recommend more studies. ‘Chlorine dioxide is effective in the treatment of COVID-19 and the mechanisms of action by which it acts to achieve it are proposed in this work. We recommend doing more research,’ wrote the researchers in their conclusion.
