Slide 18:

• Success stories in Malaria control and elimination
• Examples of countries that have successfully reduced Malaria burden
• Strategies employed – vector control, treatment, public awareness campaigns
• Eradication of Malaria in some regions like the United States and Europe

Slide 19:

• Conclusion
• Recap of the Life Cycle of Plasmodium
