Medical sources confirmed to Arabstoday that the health of former Egyptian President Hosni Mubarak is\" slightly improving\" after it was reported to have deteriorated in  Tora prison where he is serving life sentence. The sources added that Mubarak is still in intensive care in a military hospital  and is being given drugs that prevent blood clots to the brain. In response to a question about whether Mubarak would be  returning  to Tora prison hospital, the medical sources said that the decision was not in the hands of officials at the hospital whose role it is to monitor his health and provide daily reports which are available on request: \"The hospital is only responsible for monitoring the health of Mubarak, just like any other patient,  and to treat and guard him against any negative developments.\" Mubarak was exposed to a brain clot while he was in  Tora prison hospital and he was reportedly close to death, but following his transfer to a  military hospital , he is now out of danger, according to medical reports, which added that Mubarak’s clot was an expected development of his condition. It is possible that clots may return  if there are not adequate medical facilities to deal with them, which could lead to either full paralysis or death. According to the medical sources, Mubarak is infected with atrial frequency which causes clusters in platelets leading to clots inside arteries of the brain which can last for either a short or long period. This requires his presence in a fully-equipped intensive care facility where doctors can immediately deal with any problems which could recur frequently, especially in the light of Hosni Mubarak\'s health condition, and his age of 84 years, which increases the expected risk. A state of calm has prevailed in front of the military hospital in Cairo where only few supporters of the former president remain, as confirmed by witnesses to Arabstoday. Mubarak’s supporters carried posters and remained in front of the hospital for few hours, before leaving when night fell. Witnesses confirmed that were verbal altercations between supporters of Mubarak and pedestrians and motorists who accused the supporters of being against the interests of the Egyptian people. Security was tight around the hospital with the presence of armoured vehicles when the former president was transferred from Tora prison to the military hospital in Maadi. The interior minister, Mohammed Ibrahim,  had ordered the transfer because of his deteriorating health and after rumours of his \"clinical  death\" spread throughout the country.
