More than 2,000 pregnant women in Colombia have the virus, which has been linked to babies born with abnormally small brains.
The World Health Organisation, which has warned of up to four million cases this year, has called an emergency meeting in Geneva to decide whether Zika should be treated as a global emergency.
Colombia and other Latin American countries are advising women to delay getting pregnant for now given the scale of the Zika outbreak.
Diego Alejandro Garcia, from Colombia's National Health Institute, says cases continue to rise.
"We've have reports of 2,116 pregnant women of which 176 have already been confirmed by laboratory tests. That means the figures are going up."
Brazil is the worst affected followed by Colombia but the virus has now been reported in at least 23 countries and territories in the Americas and in the Pacific, in Samoa.
Indonesian officials say they detected one case of Zika last year after testing more than a hundred people during a dengue fever outbreak (Dec 2014-April 2015).
As the virus spreads, health officials in Australia are remaining alert but say there's a very low risk of transmission due to the low numbers of the type of mosquito that can transmit Zika.
The Aedes Aegypti mosquito that transmits Zika can also spread dengue fever and yellow fever, and is present in far north Queensland.
Queensland's efforts to control mosquito-borne viruses have attracted the attention of residents of Hawaii Island which has been battling a dengue fever outbreak since October.
Karen Anderson is a writer and a resident of Captain Cook on Hawaii who's campaigning for a more proactive approach to fight dengue.
She says control methods employed in far north Queensland could be used in Hawaii.
"Somebody uncovered the Queensland management plan - it was just so impressive, how comprehensive and professional and serious it was in comparison with what's been done here in the state of Hawaii to combat these mosquito-borne viruses and this particular vector."
As of last Friday, there had been 242 cases linked to the dengue fever outbreak in Hawaii, most of them residents rather than tourists.
Hawaii Island, also known as the Big Island, is popular with tourists keen to see its active volcanoes and, like all the Hawaiian islands, it's heavily dependent on tourism.
A member of the US Congress, Tulsi Gabbard, has just called on the local governor to declare a state of emergency.
She spoke to news channel KHON 2.
"I've been there on Hawaii Island, I've met with the mayor and the county officials, I have heard from numerous constituents, especially those who are living in the most heavily impacted areas, that have had the most confirmed cases and what I'm hearing from them directly is that the resources that are on the ground are not sufficient in a variety of ways."
Activist Karen Anderson says a state of emergency would not only help control dengue fever but also put the island on alert for the Zika virus.
"This declaration would unleash state money and more funds to help with the current problem and also target a sort of a long-term approach, we hope, of dealing with the overall picture of this species of mosquito that could potentially be a bearer of Zika down the line."
So far, the Hawaiian Islands are Zika-free.
Karen Anderson says an outbreak could be devastating for Hawaii.
She says travellers flying to and from Samoa, one of the 23 countries currently affected by Zika, could lead to an outbreak.
"We have a huge Samoan population here, we have Hawaiian Airlines flights that go back and forth between here and Samoa, so obviously it's a concern because it's just a Hawaiian Airlines flight away, Zika, and so when you have this problem for these mosquitoes hovering around, that can potentially carry that, this is why an emergency declaration would be important to because it's all part of the big picture that we need to deal with eradicating this potentially deadly mosquito species."
