As many as 4 million people could be infected by the Zika virus, which is rapidly spreading across the Americas and the rest of the world, and potentially even infecting children and pregnant women.
The World Health Organization is working with partners to identify and respond to the pandemic, which has been linked to thousands of deaths, including two babies born with microcephaly.
So far, there are about 3.5 million confirmed cases in the Americas, according to WHO.
If the outbreak spreads to the rest-of-world, it could lead to more severe and potentially fatal outbreaks.
In a statement, the WHO called the outbreak an unprecedented and significant threat to public health, saying that it is unprecedented for the number of cases to rise in the space of 24 hours.
A 24-hour virus The virus can infect people through direct contact, as well as through the respiratory, gastrointestinal and reproductive systems, according the WHO.
A virus can be passed from person to person through the air or through contaminated soil or water.
Symptoms of the virus can vary depending on who is exposed.
In some cases, it is not detectable by a person’s immune system, while in others, it can be detected with tests like CT scans.
While some infections can be fatal, it does not appear that there has been any confirmed cases of the Zika death virus in the United States, according Dr. Michael Whelan, an infectious disease specialist with the National Institute of Allergy and Infectious Diseases in Bethesda, Maryland.
The CDC is also working to identify cases of Zika-related birth defects.
In the United Kingdom, a team of researchers from the University of Edinburgh has reported a positive test for Zika virus in a pregnant woman, though it is unclear how the virus got into her bloodstream.
The results of that test will not be available for months, until the case is confirmed, and could take months for that test to be available in the U.K. The team also said there is currently no definitive cure for the Zika-linked birth defect, which affects babies born to women who have been infected with the virus.
If Zika does reach the U to infect people, the virus could spread quickly to people in the developing world, where there is a lot of low-income development, according Zika virus expert Dr. Eric Lander of the University at Albany, New York.
This could also lead to the spread of the disease through direct transmission, as in the case of the Uighurs in China, who recently found out their baby boy, born with Zika, had the virus and developed microcefaly.
If that happens, the risk is high that more people could become infected.
If it did, the Uryans could have become the first to have microcefar, which can cause severe developmental delays and other disabilities.
The WHO said the virus is also spreading through direct human contact, where infected people contact people who have not yet been diagnosed with Zika virus.
Some experts say the most dangerous thing about the virus in its current form is the potential for its spread to people who are pregnant or trying to become pregnant.
If someone who has been infected becomes pregnant, that person is at higher risk of transmitting the virus to the fetus, which could cause birth defects in the fetus.
If a pregnant person becomes infected, it would be difficult to know what to do about the risk, as the virus does not cause birth defect in the mother.
There are currently no vaccines for the virus, although the United Nations has called on countries to begin developing such vaccines by early 2019.
WHO is urging countries to set up testing centers to monitor pregnant women and their babies for signs of infection.
In addition to the potential risk of transmission to pregnant women, experts say that pregnant women in the middle of a pandemic should also be monitored closely to make sure they are not infected.
The virus is not contagious in the first place, but the virus cannot be spread through direct skin contact.
That means if a pregnant mother becomes infected and she passes the virus on to her baby, that baby is at greater risk of getting the disease, as there is no direct contact.
The potential for an outbreak is heightened because of the widespread use of mobile devices to carry the virus around.
The Centers for Disease Control and Prevention says that while the number and distribution of mobile phones have been decreasing, the number, frequency and timing of transmissions have been increasing.
As of Oct. 12, more than 2.5 billion people had tested positive for the viral infection, according U.S. officials.
That is up from the roughly 1.6 billion who tested positive in October, according data from the CDC.
If there is an outbreak in the USA, WHO said it would work with federal and state officials to get the virus into the hands of as many people as possible.
As the virus continues to spread, more information on the outbreak and how to protect yourself should be available on the WHO’s website.
