Health workers and researchers around the world have been struggling to keep up with the rapidly increasing cases of the newly-named Zika virus, which has also been reported in the US, Europe, China and Japan.
While the disease is now officially listed as a public health emergency, many scientists remain concerned about its effects on people’s health.
Now, a new study has looked at the health impact of the new virus on people living in the Philippines.
The researchers compared the levels of circulating antibodies in the bloodstream of people living near the border between the US and the Philippines, and those living in other parts of the world, in order to determine how much of this virus is present in the people living close to the border.
It is unclear exactly how many people are in the two countries.
But in both countries, the researchers found that, although the virus was in the majority of blood samples, the concentration of the virus in the general population was much lower.
And although there was a correlation between antibodies and the amount of circulating virus in people’s blood, this correlation was not statistically significant, the scientists wrote in their study.
“This suggests that the circulating virus is largely confined to the blood of the general public and that, to the extent that the viral burden is high, the proportion of circulating circulating virus present in people living on the Philippines side of the border is low.”
The study was conducted by researchers from the National Institute of Health in the United States, and the University of Texas Southwestern Medical Center in Dallas, the same universities that have been leading efforts to develop a vaccine for the Zika outbreak.
“In the United Kingdom, we found that the blood levels of the circulating Zika virus in individuals were comparable to levels found in non-contaminated populations,” said Dr Tanya Lee, lead author of the study, in a statement.
“Our data suggests that, for the vast majority of individuals in the community, the virus is in the same range as those of the non-infected population.”
“Although it is unclear how many cases of Zika virus are still in circulation in the world’s largest country, the WHO’s estimate of 5,300 cases is not enough to provide a realistic estimate of the worldwide burden of the pandemic,” Dr Lee added.
“This is the first study to examine how many individuals in each country are infected and how many have acquired the virus through the air.
The findings provide additional evidence that circulating virus levels in the population are higher than the WHO estimates and may provide insights into how the pandemics spread and what, if any, treatment options are available to help the affected populations.”
It was not possible to compare the levels in blood between different countries, so the researchers used an average of 10 blood samples taken from people in each region of the US for the analysis.
For the researchers, this allowed them to compare levels of antibodies in blood samples in people in different parts of each country.
They found that antibodies in people were similar in every region of America and in each of the other countries.
However, the amount and type of circulating Zika in people varies from region to region.
In the US – where there is a high concentration of circulating viruses in the air – the level of circulating viral DNA is typically higher than in the rest of the country.
In contrast, in the UK, people who have recently travelled to a country with high levels of virus are at a higher risk of acquiring the virus.
The researchers then looked at how much circulating virus was present in different regions of the blood, as well as in people from different parts, in an attempt to determine the overall level of virus circulating in people.
To do this, the team compared antibodies in different blood samples from people living across the US with antibodies in their blood from people who lived in different countries.
They found that people who live near the US border tend to have significantly higher levels of viral DNA in their plasma than people who are from other parts.
When they looked at levels of both circulating and non-circulating virus, the study found that most people living outside the US were in the range of levels found between people in countries with high viral DNA levels.
But the researchers also found that a small proportion of people who were infected were still circulating viral virus.
There was also a correlation with the levels, with people who had recently travelled from the US to another country having significantly higher concentrations of circulating and circulating virus than people living at the border, or those living elsewhere.
These results suggest that the virus that is in circulation is concentrated in a relatively small proportion in the global population and is not circulating in a large proportion of the population,” Dr Tanna Lee, a research fellow in the University’s Department of Epidemiology and Biostatistics, told ScienceInsider.
Dr Lee and her colleagues said that they were able to determine whether circulating virus had been detected in the bodies of people in the different countries because there were two sets of samples. One
