According to a recent report from the US Centers for Disease Control and Prevention (CDC), the number of tick-borne disease cases in the US has more than doubled in the last 13 years.
Data reported to the National Notifiable Diseases Surveillance System for 16 notifiable vector-borne diseases during 2004-16 were analysed, and researchers found that the number of annual reports of tick-borne bacterial and protozoan diseases increased from 22,000 in 2004 to 48,000 in 2016. Lyme disease was found to account for 82 per cent of all tick-borne disease reports during this period.
The CDC said that vector-borne diseases are a large and growing public health problem in the US and major national improvement of surveillance, diagnostics, reporting and vector control, as well as new tools, including vaccines, are required to reduce transmission and respond to outbreaks. To protect themselves from ticks, travellers should use effective repellents and treat their clothing and gear with permethrin, a type of insecticide.
