New Delhi — An epidemic of dengue fever in India is fostering a growing sense of alarm even as government officials here have publicly refused to acknowledge the scope of a problem that experts say is threatening hundreds of millions of people, not just in India but around the world.
India has become the focal point for a mosquito-borne plague that is sweeping the globe. Reported in just a handful of countries in the 1950s, dengue (pronounced DEN-gay) is now endemic in half the world’s nations.
“The global dengue problem is far worse than most people know, and it keeps getting worse,” said Dr. Raman Velayudhan, the World Health Organization’s lead dengue coordinator.
Officials say that 30,002 people in India had been sickened with dengue fever through October, a 59 percent jump from the 18,860 recorded for all of 2011. But the real number of Indians who get dengue fever annually is in the millions, several experts said.
“I’d conservatively estimate that there are 37 million dengue infections occurring every year in India, and maybe 227,500 hospitalizations,” said Dr. Scott Halstead, a tropical disease expert focused on dengue research.
“I would say that anybody over the age of 20 in India has been infected with dengue,” said Dr. Timothy Endy, chief of infectious disease at Upstate Medical University in Syracuse.
For those who arrive in India as adults, “you have a reasonable expectation of getting dengue after a few months,” said Dr. Joseph M. Vinetz, a professor at the University of California at San Diego. “If you stay for a longer period, it’s a certainty.”
