After all the bad news that have been going round over the outbreak of the Ebola virus in West African countries, Nigeria, Sierra Leone, Guinea and Liberia, a piece of good news finally arrived some moments ago.
Reporting online in the British journal Nature, researchers at the Public Health Agency of Canada announced that a prototype drug, ZMapp, that has been urgently given to a handful of patients with Ebola has cleared an important test hurdle.
According to the scientists report, the drug test results showed that ZMapp cured lab monkeys that have been infected with the Ebola virus disease.
It was gathered that it is a norm to experiment drugs on animals first and then on progressively larger groups of humans to ensure they are safe and effective.
But, in an exceptional move, ZMapp that has not gone through these tests has been rushed to the outbreak in West Africa, as the lethal disease has no cure.

The scientists informed that the drug reversed dangerous symptoms such as bleeding, rashes and high levels of enzymes in the liver.
They also stated that three “control” monkeys that had been infected, but not treated, all died within eight days.
It was gathered that 21 animals had been given the so-called Kikwit strain of Ebola, named after a location in the Democratic Republic of Congo, the country where the hemorrhagic fever was discovered in 1976.
But lab-dish tests indicate it can also inhibit the strain in Guinea which has sparked the current epidemic, the scientists said.
d is hard to produce on a large scale, are exhausted, the company said on August 12.
Investigation revealed that the other main experimental drug for the disease is TKM-Ebola, being developed by Tekmira Pharmaceuticals Corp. of Vancouver, Canada, under a $140-million (105-million-euro) contract with the Pentagon.
It is currently in a Phase I human trial, the first step in the three-phase test process. In this phase, a drug is evaluated on healthy non-infected humans to see whether it is safe. Further phases test it for safety and also effectiveness.
