U.S cities at high risk of Zika transmission


New research has revealed the list of cities in the United States that are at great risk of Zika transmission, which means citizens in these areas might be infected by Zika through mosquitos.

That list is accumulated by analyzing data on climate, mosquito breeding patterns, poverty and also air travel. In general, the highest risk stay in the Southeast part of the U.S, followed by the Eastern Seaboard and the Western U.S.

However, according to Andrew Monaghan, a climate scientist at the National Center for Atmospheric Research in Boulder, Colorado, other evidence indicates that were Zika to spread in the U.S, the risk of local transmission in even the cities of greatest risks is still small, which only affects dozens of people at the maximum level. He said that the overall risk in America remains low.

Recently, Zika virus has ben widespread across the Latin Americas and Caribbean, becoming an epidemic. That virus is transmitted to people through mosquito’s bites. Only 1/5 of the people who are infected by Zika show the symptoms, though these are just mild symptoms. Normally, Zika causes fever, red eyes, rash and joint pain. However, when it comes to pregnant women, Zika is suspected of causing microcephaly – a birth defect which causes tiny head and brain damage in babies of infected women.

Zika is also said to link to Guillain-Barre syndrome, a rare form of temporary paralysis that can hurt people of every age.

The Centre for Disease Control and Prevention said that there was likelihood that Zika virus would spread to the U.S as the virus that transmit that virus had lived in that country for hundred of years.

Mosquitos brought about disease outbreaks in the past, yet the possibility of spreading today is much lower, due to the changes in mosquito breeding sites and human habits.

Monaghan explains that almost people in the U.S tend to spend most of their time in air-conditioned rooms with screened-in windows. Therefore, the chances for mosquitos to bite them are very few. Also, the small number of pockets of spending water where mosquito and good mosquito control efforts from U.S citizens greatly contribute to the low risk of zika transmission.

Though the risk of Zika spreading is very low, no one can conclude that the American people will not be infected by that virus. Therefore, measures, especially mosquito control efforts need to be made in order to minimize the risk of getting contracted by Zika in the U.S, Monaghan suggests.
