 Belgrano also experienced paludism (malaria) during the second campaign to Upper Peru. On 3 May 1815 he informed the government of his disease, which made it difficult for him to work or even talk. He was treated by doctor Joseph Readhead, who employed a local species of the Cinchona medicinal plant. The disease lasted up to his stay in Britain, when his health improved because of the treatment and by having left the endemic zone.
