Which countries have been declared malaria-free by WHO in May 2019?

Correct option is B

The correct answer is:(B) Algeria and Argentina

Explanation:
In May 2019, the World Health Organization (WHO) declared Algeria and Argentina as malaria-free countries. This achievement was a result of extensive efforts to control and eliminate malaria, including successful public health interventions, vector control programs, and improved access to diagnostics and treatment.

Information Booster:

• Algeria was declared malaria-free after no locally transmitted cases were reported for three consecutive years.

• Argentina achieved this milestone after a consistent reduction in malaria cases over many years, with the last known case of local transmission in the country being recorded in 2010.

Additional Information:

• The WHO malaria-free certification is granted to countries that have successfully interrupted local transmission of malaria for at least three consecutive years.

• Countries like Mauritius and Malaysia have also made significant progress in malaria control, but they were not the focus of the 2019 certification.
