The WHO noted that there is no scientific evidence that chloroquine is a safe and effective medicine against COVID-19.

The World Health Organization (who) does not support the decision of the Government of Brazil to approve the use of the chloroquine and the hydroxychloroquine for the treatment of coronavirus COVID-19, because there is no scientific evidence that it is a safe and effective medicine against this disease.

“The clinical evidence do not endorse the use of this medicine and it is not recommended at least until there are clear results from the clinical trials“Said the director of the WHO Health Emergencies ProgramMike Ryan at a press conference in Geneva.

He added that the investigations of the WHO regional office for America, known as Pan American Health Organization (OPS), have not reached conclusions that would recommend it either.

The Brazilian Ministry of Health published on Wednesday, by indication of the president Jair Bolsonaro a protocol for the treatment of patients with coronavirus, which covers the use of chloroquine and hydroxychloroquine in mild cases.

Chloroquine is a medicine widely known as antimalarial and to try rheumatic diseases, and hydroxychloroquine is its derivative (they have the same components), but it is considered to be better tolerated.

Both are part of the group of drugs which are being studied in many countries as possible treatments for COVID-19.

Ryan recalled that there is no evidence to support its usefulness as a treatment or as prophylaxis, that is, to prevent the new coronavirus.

“Some regulatory authorities have advised that this drug should be reserved for the clinical setting and (its eventual use should be made) under close medical supervision for the side effects that it can have in serious patients, like cardiac complications and arrhythmias“Said the doctor.

Brazil has more than 310 thousand confirmed cases of coronavirus and has exceeded 20 thousand deaths because of this.

The positive curve records a constant rise and the latest daily data confirms the death of 1,188 people in a single day.

Ryan confirmed that the majority of cases focus on Sao Paolo and Rio de Janeiro, but also expressed concern about the situation in the country’s vast Amazon region and the state of Pernambuco.

According to the data he offered, the situation is alarming in the Amazon region, with 499 infected people per 100,000 inhabitants, a rate considered very high.

The WHO, he added, is assisting the Government of Brazil in its fight against pandemic.
