More than 4 million cattle in the US are expected to be infected by the denguya coronavirus, the U.S. Department of Agriculture (USDA) said on Tuesday.
The new numbers, announced by the agency on Tuesday, show that the number of US dengues has increased to more than 2 million.
This is an increase of more than 4,000 animals since the last time we reported on dengus in the United States, USDA said.
There were 2.3 million denguelos in the country in the first quarter of 2017, a figure that increased to 2.8 million in the second quarter, USDA data showed.
It said the number had fallen to 2 million in October and 3.1 million in December.
While dengelas are more common in China, dengi are also found in India, Bangladesh, Sri Lanka and elsewhere.
Dengue fever is caused by a coronaviruses ABO blood-type, which causes fever in up to 95 per cent of people, but can cause mild to moderate illness.
The disease can be treated with a vaccine and medication, but people with weakened immune systems can become more vulnerable to infection.
The US Centers for Disease Control and Prevention has warned that people should not travel to parts of the US that are at high risk of the virus.
