Joseph Smith Can Heal Malaria

The Primary Lesson make is very clear that Joseph Smith has the miraculous power to cure malaria.  This post is not questioning that.  The problem is that the lesson makes no mention of the fact that at least 175 people died of malaria in Nauvoo between 

Part of the story in the lesson says, " ‘Brother Fordham, I command you in the name of Jesus Christ to arise from this bed and be made whole.’ His voice was like the voice of God, and not of man. It seemed as though the house shook to its very foundations."

BYU Studies - Article - Deaths in Early Nauvoo

From the BYU Study:  "Malaria was the most common cause of death in Nauvoo. Since Nauvoo was a swamp before the Saints arrived, it was undoubtedly a haven for mosquitoes."

"There was an average of about 40 recorded deaths each year from Malaria"

Nauvoo in the Mormon Period

Entire quote from the manual:

The Saints Do the Lord’s Work

The Saints did the Lord’s work by helping others, and in return the Lord helped the people of Nauvoo. When the Saints first came to Nauvoo, the land was very swampy. The Saints did not know that the mosquitoes that thrived in the swamplands spread a dangerous disease called malaria. Many of the Saints came down with this disease, which caused severe chills and fever. Emma Smith nursed many people, and her six-year-old son helped her by carrying water for the sick until he also came down with malaria. Even the Prophet was sick. The Lord blessed the people, however, giving the Prophet the ability to heal them. Wilford Woodruff reported what happened when a group of priesthood holders led by Joseph Smith visited the home of one sick man:

“The next place they visited was the home of Elijah Fordham, who was supposed to be about breathing his last. When the company entered the room the Prophet of God walked up to the dying man, and took hold of his right hand and spoke to him; but Brother Fordham was unable to speak, his eyes were set in his head like glass, and he seemed entirely unconscious of all around him. Joseph held his hand and looked into his eyes in silence for a length of time. A change in the countenance of Brother Fordham was soon perceptible to all present. His sight returned, and upon Joseph asking him if he knew him, he, in a low whisper, answered, ‘Yes.’ Joseph asked him if he had faith to be healed. He answered, ‘I fear it is too late; if you had come sooner I think I would have been healed.’ The Prophet said, ‘Do you believe in Jesus Christ?’ He answered in a feeble voice, ‘I do.’ Joseph then stood erect, still holding his hand in silence several moments; then he spoke in a very loud voice, saying: ‘Brother Fordham, I command you in the name of Jesus Christ to arise from this bed and be made whole.’ His voice was like the voice of God, and not of man. It seemed as though the house shook to its very foundations. Brother Fordham arose from his bed and was immediately made whole. His feet were bound in [bandages], which he kicked off, then putting on his clothes, he ate a bowl of bread and milk, and followed the Prophet into the street” (quoted in Joseph Fielding Smith, Essentials in Church History,pp. 223–24).
