He remained Bishop of Radom until his appointment as the President of the Pontifical Council for the Pastoral Care of Health Care Workers in 2009. He was at the same time raised to the dignity of Archbishop ad personam. In addition to his native Polish, Archbishop Zimowski speaks Italian, German, English, French and Russian. In January 2011 Archbishop Zimowski said that "Leprosy, in fact, after the upgrading of effective pharmacological therapies, witnessed a notable reduction of the lethal infection, but continues to cause suffering, diminution and social exclusion. Flourishing around it are ignorance, inequality and discrimination that, in turn, fuel its diffusion". He noted that from a statistical point of view, the countries that are most affected are in Asia, South America and Africa. India has the greatest number of affected people, followed by Brazil. Numerous cases are recorded also in Angola, Bangladesh, the Central African Republic, the Democratic Republic of the Congo, Indonesia, Madagascar, Mozambique, Nepal and Tanzania. He said that "Hansen's disease is an 'ancient' illness, but, because of this, no less devastating physically and also morally," Archbishop Zimowski reflected. "In all ages and civilizations, the fate of the leprosy sufferer is marginalization, being deprived of any type of social life, condemned to seeing his body disintegrate until death comes." On 4 May 2011, Pope Benedict appointed him a member of the Congregation for the Causes of Saints. On 18 May 2011, in a speech to the annual assembly of the World Health Organization in Geneva, Switzerland, he said that the world seemed "stalled in the status quo where the rich people have higher levels of coverage, while most of the poor people miss out, and those who do have access often incur high, sometimes catastrophic costs in paying for services and medicine." He raised objections to needle-exchange programs and called for increased funding for poor nations. On 2 April 2012, World Autism Awareness Day, Archbishop Zimowski said that "The Church needs to address the alienation often surrounding those living with autism, especially children and young people, by coming to the aid of those affected". He added: "The church sees as impelling the task of placing herself at the side of these people – children and young people in particular – and their families, if not to break down these barriers of silence then at least to share in solidarity and prayer in their journey of suffering". In May 2012 Archbishop Zimowski, as head of the Holy See delegation to the 65th World Health Assembly, reaffirmed the Holy See's support for Resolution WHA64.9 on "sustainable health financing structures and universal coverage," which urges member states to aim for affordable universal health care coverage and access for all citizens on the basis of equity and solidarity. Zimowski said "more countries, especially those with emerging economies, are moving towards universal coverage," thanks also to "good policies that promote equity.... Therefore my delegation strongly believes that in the endeavor to promote universal coverage, fundamental values such as equity, human rights and social justice need to become explicit policy objectives". The archbishop made an appeal for high-income countries to show greater solidarity toward poorer nations in order to overcome funding shortfalls in health. On 28 July 2012, Archbishop Zimowski was named a Member of the Congregation for Bishops by Pope Benedict XVI. Zimowski died in Poland on 13 July 2016, while convalescing following treatment for pancreatic cancer.
