On Monday, President Buhari of Nigeria went to London for a 4 day private visit, New York Times reported. His assistant confirmed to the media that the president had visited the doctor when he visited England. Since Buhari was elected president in 2015, he has travelled to London several times to launch medical travel. Last year, Buhari asked for more than four months of sick leave to go to London for treatment, but he did not make a public illness. It made the people think about it, and many people asked the president to step down on the grounds of health. In fact, it is not uncommon for politicians to receive treatment abroad. Some politicians are even keen to seek medical treatment overseas. Better medical services Looking at the world, African politicians seem to be especially keen on overseas medical treatment. A few months ago, Patrice Talon, President of the Republic of Benin, underwent surgery in France. Shortly after leaving office, former president Dos Santos of Angola was treated in Spain. During the past more than 30 years, former president Robert Mugabe of Zimbabwe often flew to Singapore to see eye diseases. According to the TheConversation, Africas public health system is frustrating. Preventable diseases still cause death of a large number of women and children. Many hospitals can only sleep on the floor. In recent years, more and more wealthy and high-ranking officials from Africa have chosen to go abroad for medical treatment. In 2016, Africans spent more than $6 billion overseas for medical treatment, while Nigeria contributed $1 billion a year. During the general election in Nigeria, Buhari promised to end the medical travel of the officials. Although this government will not deny the basic human rights of anyone, we certainly do not encourage Nigerias hard won resources to be spent on any government officials seeking overseas medical care. However, after months of silence, Buhari broke his promise and opened his first medical trip in London. Nigerians believe that he is not the same as he is. He does not invest in domestic medical and health infrastructure, but he enjoys high-quality health care services overseas. This year, Nigerias budget for health care accounts for only 3.9% of the total budget, far below the target of 15% of the United Nations. However, when Buhari visited Britain last year, the downtime cost would be as high as 360 thousand, equivalent to 0.07% of Nigerias budget this year. In addition to African dignitaries, politicians in developing countries such as Burma, Venezuela and Peru will also go abroad for medical treatment in pursuit of better medical conditions. A more secure political choice Overseas medical treatment is also a political choice and a means to avoid and resolve political crises. Usually, once a politician has health problems, the alarm bell of his political career will also be heard. Therefore, in many countries, the health of political leaders is regarded as state secret. In order not to let the political enemies know the secret and retain their supporters, some politicians choose to go abroad for medical treatment. Other politicians want to protect their lives in the name of overseas medical treatment at a critical juncture. In June 2011, the Yemen government forces and rebels were fighting in the capital SANA, when President Saleh was shelled at the presidential palace and wounded in Saudi Arabia for treatment. After Saleh returned home, the domestic situation continued to be turbulent, and the negotiations between the ruling party and the opposition party were deadlocked. The opposition even staged demonstrations demanding trial of Saleh. Facing the tense situation, Saleh went to the United States to take refuge in the name of going to the United States for medical treatment. Despite this step, the Yemen crisis was settled at a relatively low cost.
