The Senate is slated to vote today on three competing plans to battle the virus, with a bipartisan plan that cuts Obama's USD 1.9 billion request to USD 1.1 billion having the greatest chance to advance. The procedural vote would pave the way to add funds for the government's response to Zika to an unrelated spending bill.
For pregnant women, Zika can cause a serious birth defect called microcephaly and other severe fetal brain defects, as well as eye problems, hearing deficits and impaired growth. Zika is commonly spread by mosquitoes and can also be contracted through sexual contact.
Zika is expected to spread more widely during the summer mosquito season, but officials say outbreaks in the US are likely to be limited. To date, there have been more than 500 cases of Zika in the continental US, all of which so far have been associated with overseas travel.
Obama requested the funding in February and has been forced to tap unspent 2015 funds from the successful battle against Ebola to finance almost USD 600 million in anti-Zika efforts.

The White House and its Democratic allies have been sharply critical of Republicans controlling Congress over delays in providing additional funds, which they say is required for mosquito control, purchasing diagnostic tests and developing and manufacturing a vaccine.
House Republicans yesterday unveiled their Zika proposal, which would slice Obama's request to USD 622 million and pair it with offsetting spending cuts to unspent Ebola funding and leftover money at the Department of Health and Human Services.
The House measure will advance as a stand-alone bill and it's unclear how difficult it will be to forge a compromise between the two chambers.
