The recent influx of migrant labourers into Bareilly, Uttar Pradesh from various urban centres has raised concerns about the spread of COVID-19 in the region. To mitigate this, a controversial approach involving an open bath with disinfectant for the returning migrants has been implemented.
The Use of Disinfectants on Migrants
The nodal officer responsible for COVID-19 responses in Bareilly confirmed that the disinfectant was merely a combination of chlorine and water. However, the Medical Officer of Bareilly contradicted this claim by asserting that the migrants were sprayed with a sodium hypochlorite solution. This is the same substance used in other Indian states such as Gujarat, Maharashtra and Punjab for sanitising buildings and solid surfaces in an effort to eliminate any traces of the novel coronavirus. The intention behind this approach was framed as concern for the safety of the incoming migrants who were transported by government-operated buses, ostensibly to minimise potential disease transmission.
The Controversy Surrounding Sodium Hypochlorite
In response to this controversial method, the District Magistrate ordered disciplinary action against those officials who imposed the disinfectant baths on the migrants without considering possible adverse effects on human health. Meanwhile in Delhi, a 1% sodium hypochlorite solution was applied to the possessions of migrant workers. This concentration could potentially harm the skin upon contact.
About Sodium Hypochlorite
Sodium hypochlorite is predominantly utilised as a disinfectant and a bleaching agent. Additionally, it is used to sanitise swimming pools. It emits chlorine which is also a disinfectant, however, large quantities can be dangerous.
Common household bleach is typically a 2-10% sodium hypochlorite solution. At a reduced concentration between 0.25-0.5%, the chemical is used for treating minor skin injuries such as cuts and scrapes. An even lesser solution, 0.05%, is used in some handwash products.
However, sodium hypochlorite is corrosive and its main use is for cleaning hard surfaces. If ingested, it can cause serious harm to the lungs and even a 0.05% solution could be extremely harmful to the eyes. It may cause itching or burning and is not recommended for usage on human beings, especially in the form of a spray or a shower.
Effectiveness Against Novel Coronavirus
The World Health Organization (WHO) and the US Centers for Disease Control and Prevention advocate the use of homemade bleach solutions with 2-10% concentrations for cleaning hard surfaces to treat them against the coronavirus. According to a tutorial from Michigan State University, cleaning hard surfaces with this solution can also help prevent the flu, foodborne illnesses and more. However, precaution should be taken to utilise the bleach in a well-ventilated area and gloves should be worn when handling the product or solution.
