This results in "congenital Zika syndrome", with children born with neurological problems including microcephaly, causing abnormal brain development and smaller heads. Also, another team reported that Aedes albopictus, another species that can transmit Zika and other diseases, has become established and are spreading in CT, which had been considered the northern part of it range.
In glioblastoma, the cancer cells resemble those in the developing brain, suggesting that the Zika infection could attack them too. The number of pregnancy losses related to the virus remained at eight. The research team's paper was published May 19 in Nature Communications.
The virus-transmitting Aedes aegypti mosquitoes thrive in subtropical, tropical and some temperate regions.
The results showed that mosquitoes in the lab can transmit all three viruses simultaneously, although this is likely to be extremely rare in nature.
"A mosquito, in theory, could give you multiple viruses at once", said Claudia Ruckert, post-doctoral researcher at Colorado State University in the US. The viruses become established and replicate in the midgut. "On the one hand, all of these viruses have mechanisms to suppress mosquito immunity, which could lead to synergy".
The CSU team infected mosquitoes in the lab with multiple kinds of viruses to learn more about the transmission of more than one infection from a single mosquito bite.
"Dual infections in humans, however, are fairly common, or more common than we would have thought", she said. Thirty percent of women said they would likely keep it a secret if they were diagnosed with the virus. "It could definitely lead to misinterpretation of disease severity".
The team now wants to examine yellow fever, a fourth virus that is carried by Aedes aegypti, as a possibility for coinfection with chikungunya, dengue or Zika viruses.
"Finding new ways to treat brain tumours to help more people survive the disease is a priority for Cancer Research UK".
They examined genetic sequences from clinical isolates from the outbreak in the Americas, comparing them with those of an Asian-lineage Zika strain isolated in Cambodia in 2010.
A Culex quinquefasciatus mosquito is seen on the skin of a human host in this 2014 picture from the Centers for Disease Control and Prevention.
There were two reported West Nile virus cases and three cases of St. Louis Encephalitis, a similar mosquito-borne illness, in Clark County in 2016. Populations have increased every year since then, except for during 2014 and 2015, after especially cold winters. He will look to see how the virus targets stem cells and to see if there are any adverse effects.
