  • Deception (50%)
    The article is deceptive in several ways. Firstly, the author claims that dengue cases have exceeded historical figures when compared to activity over the last five years. However, this statement is not supported by any data or statistics provided in the article. Secondly, the author states that there are no known cures or vaccines for dengue virus but symptoms can be treated with medication. This statement is misleading as it implies that treatment options exist when in fact none have been proven to cure dengue fever and only provide symptomatic relief.

  • Fallacies (70%)
    The article contains several fallacies. The author uses an appeal to authority by citing the World Health Organization (WHO) and Dr. Stacey Rizza from the Mayo Clinic as sources for information about dengue fever. However, these sources are not directly related to Puerto Rico's public health emergency declaration or its specific situation with mosquito-borne infections.
    • The WHO has warned the endemic is the fast-growing mosquito-borne illness worldwide and is likely a result of a changing climate, an El Niño pattern, human conflicts and poor access to healthcare.
  • Bias (85%)
    The article contains examples of religious bias and monetary bias. The author uses language that dehumanizes people who are infected with dengue fever by referring to them as 'bloodsuckers'. Additionally, the article mentions a company called Mosquito Landscaping which provides services for keeping mosquitoes away from homes. This implies that there is money being made off of the fear and concern surrounding mosquito-borne infections.

              • Deception (50%)
                The article is deceptive in several ways.

Secondly, the author quotes Dr. Carlos Mellado Lopez as saying that there has been a 140% increase in cases from Jan. 1 to March 21 compared to the same period last year without providing any context or data for this comparison. Thirdly, the article uses sensationalist language such as 'dengue fever cases continue to rise' and 'about one in four people develop symptoms lasting two to seven days', which can be misleading and alarming for readers. Lastly, the author does not provide any information on how effective vaccines are against dengue or if they have been administered in Puerto Rico.

This is presented as fact without any evidence or context provided. Additionally, the article mentions that municipal leaders have played a crucial role alongside the Department of Health in addressing dengue, which could be seen as biased towards those who are actively working to combat the disease.
