There are 2 kinds of Dengue: The first one is kind of similar to covid-19 with symptoms like headache, bone ache and can last for some days to weeks but no further issues after being sick and the second one is very dangerous with high fever, anxiety, cold sweats, tachycardia, blood clotting problems and it might be lethal. With treatment, survival rate is about 99%.

The Aedes Aegypti mosquito again.Incubation time for this disease is from 2 to 12 days and then the infected person will feel extremities pain, fever and acne. Symptoms last around 10 days and they disappear on their own and grant immunity.
This one is the least common of the 3 and cases reach a lower rate every year. There are no vaccines and no treatment. In case of infection, symptoms are treated.
In Costa Rica, Malaria is very uncommon. Last time cases of this disease were reported was 5 cases in 2019.
Costa Rica is not affected by Yellow Fever. But if you have been in a country where this disease is present, every person older than 9 months has to provide a certificate of Yellow Fever vaccination to enter Costa Rica. The shot has to be taken 10 days before getting into the country.
