More than 50 percent of the world’s population, including the United States, is living in areas with high rates of mosquito-borne diseases.
The Centers for Disease Control and Prevention has warned of a surge in the virus, with a high death toll.
“It’s not a new situation for us, and we are well aware of it,” Dr. Anthony Fauci, director of the CDC, said at a news conference on Tuesday.
Aedes aegypti is a mosquito species that is found in Central and South America.
Its populations have become highly resistant to a broad range of vaccines, including some in the United Kingdom, France and Australia.
Vaccine failures are the main cause of the pandemic, and scientists have estimated the vaccine failure rate in the U.S. to be over 50 percent.
For many years, the CDC has been working with the world-wide coalition of public health organizations to develop vaccines that work in different regions.
Dr. Faucs team, which is composed of doctors, epidemiologists, scientists and a research scientist, has been looking at how to protect the world.
They hope their work will lead to a vaccine that works in the West, and to the United Nations’ declaration of Zika as a global public health emergency.
They also want to use the Zika pandemic to educate people about the disease, to help those who have the virus and to promote education about how to prevent the disease.
While many experts are saying the virus is no longer contagious in the wild, the Centers for Diseases Control and the National Institutes of Health said it could spread in areas where mosquitoes are not prevalent.
Fauci said the virus could be transmitted through contact with infected people, including if they have recently traveled to another country.
He said the most important thing now is to get people vaccinated, and the CDC is encouraging people to get tested.
At a news briefing, Dr. Daniel Gomes, an infectious disease expert with the World Health Organization, said it is important to take precautions, but the vaccine is not yet ready for use.
Gomes said that if there is a pandemic and the virus spreads quickly, there may not be enough vaccines to fight the virus.
As a precautionary measure, people should not travel to areas where there are higher rates of the virus in the population.
