6 liters of water to be used each day.116 This also led to very poor hygiene conditions, as stated by expert witness Castro-Conde.117 90. With respect to health care, it was established that it was not only insufficient, but on many occasions non-existent. The Court recalls that personal integrity is directly and immediately linked to human health care.118 Indeed, the Court has pointed out on several occasions that the State has the duty to provide detainees with regular medical check-ups and adequate care and treatment when required119 and that the lack of adequate medical care to a person who is deprived of liberty and under the custody of the State may be considered a violation of Articles 5(1) and 5(2) of the Convention, depending on the specific circumstances of the specific person, such as their state of health or the type of ailment from which they suffer, the length of time elapsed without care, its cumulative physical and mental effects, and, in some cases, the person's sex and age, among others.120 In the instant case, the Court notes that there was an almost total absence of medical supplies and trained medical personnel to care for the inmates, which also increased the incidence of physical and mental health problems.121 This is compounded in particular by the absence of mental health care, which precluded any possibility of alleviating the mental anguish suffered by death row inmates.122 Also linked to the above, with respect to food, the Court notes that there was no adequate diet to the medical conditions of inmates who suffered from diabetes, hypertension or ulcers (supra para. 85), which also worsened the effects of their illnesses.123 Cf. Expert report of Aída Castro-Conde Barrios on the state of mental health of Miguel Ángel López Calo and Miguel Ángel Rodríguez Revolorio, June 23, 2005 (evidence file, folio 265). In relation to access to water, Rule 15 of the United Nations Standard Minimum Rules for the Treatment of Prisoners establishes that "[p]risoners shall be required to keep their persons clean, and to this end they shall be provided with water and with such toilet articles as are necessary for health and cleanliness. On the other hand, Rule 20.2 of the aforementioned legal document states that "[d]rinking water shall be available to every prisoner whenever he needs it."
