(source image: PAHO Zika weekly report, accessed 19.11.2021) The high incidence in Guatemala compared to the other countries is striking. However, these numbers need to be interpreted with caution, as epidemiological surveillance may be limited due to the COVID-19 pandemic. Case numbers in the Caribbean are incomplete, see link for details.
Consequences for travelers
Currently, none of the above countries is classified as an area with a current outbreak (see CDC map). Prevention: Optimal mosquito protection is necessary around the clock (24/7): during the day against dengue, chikungunya, Zika and other viruses, at dusk and at night against malaria. If you should have a fever: take medication containing the ingredient paracetamol and make sure you drink enough fluids. Do not take any medication containing the ingredient acetylsalicylic acid (e.g. Aspirin®), as this may increase the risk of bleeding in the event of a dengue infection (see also factsheet dengue). If you have visited a malaria area and have a fever >37.5 °C, you should always exclude malaria by taking a blood smear on the spot. Visit a medical facility for this (see also factsheet malaria). Detailed information on Zika can be found in the Zika factsheet.
