Public health officials in the US have admitted that Zika virus is scarier than it was thought at the beginning and that it has a greater impact in the country than it was predicted.
Dr Anne Schuchat of the US Centers for Disease Control and Prevention said that numerous birth defects can be associated with the virus.
She added that the mosquitoes which carry the virus may travel to more US states than thought previously.
The Zika virus first broke out in Brazil close to a year ago.
Thousands of birth defects in the US have been linked to it.
“Most of what we’ve learned is not reassuring,” said Dr Schuchat at White House briefing on Monday.
“Everything we know about this virus seems to be scarier than we initially thought.”
President barrack Obama earlier this year asked for $1.8bn from the Congress so as to finance the fight against the virus.
As at the moment, it has been using money that was left from the Ebola virus fund. This totals to $589m.
Dr. Anthony Fauci said that the move was a temporary one and was not sufficient to finish the job.
He said that more funds will be needed by the US to combat the mosquitoes and fund research into vaccines and treatment.
“When the president asked for $1.9 billion, we needed $1.9 billion.”
As he tried not to sound as an alarmist, he said latest discoveries showed how destructive Zika can be to the brains.
There were also reports of rare neurologic problems in adults, he said.
