No fewer than four persons have been reported dead in the United States after drinking hand sanitizer.

This is according to a report by the US Centers for Disease Control and Prevention which said it received notification of 15 cases of methanol poisoning associated with ingesting the alcohol-based hand sanitizers in recent months.

The 15 cases, including four deaths, were reported in Arizona and New Mexico state from May through June 30, according to a CDC report published Wednesday.

Among the four patients who died, three had seizures when they were hospitalized. And three other patients were discharged with vision loss after treatment, according to the CDC.

In early July, the Food and Drug Administration issued a warning, saying “Methanol, or wood alcohol, is a substance that can be toxic when absorbed through the skin or ingested and can be life-threatening when ingested.”

Washing and disinfecting hands can effectively help curb the spread of COVID-19 while swallowing hand sanitizer can not, CDC said, adding that why the patients drank hand sanitizers remains unclear.

Similarly, back in April, accidental poisonings from disinfectants were rising after President Donald Trump suggested that injections of disinfectants could help defeat the coronavirus during a daily briefing on COVID-19.
