US President Barack Obama has criticised the United States Congress for failing to back his request for a $1.9bn (£1.25bn) fund to combat the spreading Zika virus.
He warned that the country could face “bigger problems” in the future.
His comments came as the latest figures showed that there were nearly 300 pregnant women in the U.S who had tested positive for Zika.
The virus is thought to cause serious birth defects. It is spread through mosquitoes and sexual contact.
The World Health Organization has declared the Zika virus a global public health emergency. It can cause microcephaly, a birth defect, marked by a small head size and can lead to developmental problems in infants.There have been around 1,300 confirmed cases of microcephaly in Brazil, with thousands more under investigation.
Symptoms of Zika virus include mild fever, conjunctivitis, headache, joint pain and rashes.
On Friday, President Obama said the Senate had agreed to only half of the required funding, and the House of Representatives only a third.
He said that even this money ($589m) had been diverted from funds earmarked to tackle the threat of Ebola.
