The World Health Organization (WHO) announced that its scientists investigate
“We asked our experts to identify if there is evidence. For now it is too early to say something about it,” said a spokesman for IABG, Gregory Hartl.Since the alarm bells ringing in Mexico last April 30, the virus has spread around the world, but not yet considered by WHO as a pandemic. There are more than 5,700 infected in 33 countries, according to the organization in Spain, has already reached the hundreds of patients.
Hartl has stressed that the priority of the WHO remains to determine the risk of the new virus, to assess their development and help countries prepare for a pandemic.
Adrian Gibss scientist, who participated in the formulation of the antiviral oseltamivir (Tamiflu), used in the treatment of the new flu, said that the genetic characteristics of H1N1 viruses would suggest that was grown in eggs, a method used in laboratories.
For his part, Dr Sylvie Briand, expert from influenza program of WHO, has responded to reports of a suspected virus resistance to both zanamivir and oseltamivir, the other drug considered effective for influenza A.
Confused with seasonal flu
“The virus reacts to the two drugs”, has confirmed Briand, who explained that doubts are due to be confused with seasonal flu, “the previous year and showed some resistance” to these antivirals.
With regard to the possibility that this new virus is less dangerous than feared, the expert said he was being compared with the cause of the 1918 pandemic and acknowledged that two viruses appear to be “different characteristics.”
“But that’s not enough to say that this is a mild virus because it is quite new,” he added, to remind you also know “how people react to new pathogens.”
