Diseases from ticks and mosquitoes on the rise: CDC


Diseases from ticks and mosquitoes on the rise: CDC

Everyone in the USA loves the onset of warm weather, but possibly no one more than ticks, mosquitos, and fleas.

State and local public health officials must also be proactive in prevention measures, as well as diligent in reporting incidences of pest-borne diseases, the researchers said.

In 2016, there were 96,075 reported cases.

Also, Puerto Rico's first chikungunya virus epidemic peaked in 2014, followed by the Zika virus in 2016.

The study had some limitations, including that the only vector-borne disease cases included in the data were those reported to public health authorities, so the number of cases could be substantially under-reported.

According to the CDC, diseases from mosquito and tick bites happen in every US state and territory.

Lyme disease, ehrlichiosis, and anaplasmosis are the most common illnesses caused by tick bites. Accordingly, mosquito-borne diseases in the USA went up from about 5,000 cases in 2004 to nearly 48,000 in 2016.

Illnesses from tick, mosquito and flea bites more than tripled between 2004 and 2016. West Nile virus, also spread by mosquitoes, is widespread across the continental United States where it is the major mosquito-borne disease. "What I can tell you is increasing temperatures have a number of effects on all these [insect]-borne diseases".

Mosquitoes and ticks are increasing in number and moving into new areas, carrying with them the diseases they transmit through their bite, the report said.

Overseas travel and commerce are more common than ever.

"Our nation is not fully prepared to deal with this new onslaught of vector-borne diseases", Petersen said.

"Warming temperatures associated with climate change are projected to increase the range of suitable tick habitat and are therefore one of multiple factors driving the observed spread of Lyme disease", the EPA said.

"We have seen an increase in the types of tick-borne pathogens".

More moderate winters are likely to blame, allowing ticks and mosquitos to thrive in areas that would have previously been uninhabitable.

"Vector-borne diseases such as Lyme disease and Zika virus disease can devastate patients and their families, causing significant suffering", said Dr. Paul Auwaerter, president of the IDSA. The most common type of biting ticks in IL are the American dog tick and the lone star tick.

Lyme disease is often treatable with antibiotics.

"It's something we're certainly concerned with and we're aware of, but there's no simple answer to the question", Rosenberg said. Previous year there were 89 cases of West Nile in 80 different counties, the health department said.

The CDC estimates that more than 300,000 people get Lyme disease every year, thought only about 35,000 cases are reported.
