Diseases From Ticks and Mosquitoes Have Tripled

Diseases From Ticks and Mosquitoes Have Tripled

Diseases transmitted by ticks, fleas, and mosquitoes are becoming more risky and far more numerous: Between 2004 and 2016, they tripled to almost 650,000 cases, a new CDC report finds. Lyme disease is the most common tick-borne illness, and the CDC researchers found the area where Lyme disease exposure is a risk has been growing in recent years.

"Nine new germs - seven of them spread by ticks - have been newly introduced or discovered in the United States since 2004", he added.

According to the Times, CDC director Robert Redfield advocated for more support for local public health departments, which the newspaper notes are "chronically underfunded".

The findings, published in the CDC's Vital Signs report, were based on data reported to the National Notifiable Diseases Surveillance System from 2004 through 2016. "There is a role for everyone". Unlike tick-borne diseases, which are not infectious, mosquito-borne diseases are.

Mosquito-borne infections are most likely to hit sunnier states and territories.

Although the incidence of vector-borne diseases rose steadily since 2004, 2016 experienced a huge spike in mosquito-borne disease compared to previous years because of the appearance of Zika, with 41,680 cases alone that year.

Cases of tick-borne diseases doubled during the study period, from about 22,500 in 2004 to about 48,600 in 2016.

"Among the diseases on the list that are caused by indigenous pathogens are Lyme disease (Borrelia burgdorferi); West Nile, dengue and Zika virus diseases; plague (Yersinia pestis); and spotted fever rickettsioses", they wrote.

West Nile virus, the major mosquito-borne disease in the continental United States, can be found widely distributed across the country. Higher temperatures tend to make mosquitoes more infectious and infectious faster, thus promoting outbreaks. "They are spread by movements of people or animals or vectors, and with expanding global travel and trade, all diseases are basically a plane flight away", he said.

"Many of these diseases are sensitive to increasing temperatures", he told reporters on a conference call.

"It enables these ticks to expand to new areas". That's enough to help nine states to increase their ability to manage vector-borne disease, Petersen said.

The researchers noted that these illnesses often go unreported; for instance, a person may have contracted Zika or West Nile virus but have never gone to the doctor.

Officials say the actual number of people who have become sick is much higher, in part because many infections are not reported or recognized.

In a 2017 report from the Medical Society Consortium on Climate and Health, an organization representing 500,000 clinical practitioners aimed at taking action against climate change, Damle shared that over the past five years, his practice has seen a significant rise in tick-borne diseases, including Lyme disease and other infections.

The CDC said more than 80 percent of vector-control organizations across the United States lack the capacity to prevent and control these fast-spreading, demanding illnesses.

"We understand that Congress and the administration have many hard choices to make", he said.

Warmer weather is an important cause of the surge in cases reported to the Centers for Disease Control and Prevention, according to the lead author of a study in the agency's Morbidity and Mortality Weekly Report.
