Current experiences at a global level are an inspiration for research in the academic field. There is much to learn, and society must carefully reflect on the moments lived in two years that for many have meant two centuries. Many difficulties remain to be resolved and a wide field to discover the unknown by medicine. With the difficulties that have arisen on a global scale because of COVID-19, health has been affected at the societal level; In addition to the consequences derived from the effects of the virus, the mental health of people was impacted with high repercussions at the social and family level, as well as the teaching processes at the different levels of education where many students abandoned their studies.

The nurse has an important role caring for the patient infected with the coronavirus disease (COVID- 19). It is an infectious disease caused by the SARS-CoV-2 virus. The virus can spread from the mouth or nose of an infected person in small liquid particles when they cough, sneeze, speak, sing, or breathe. These particles range from larger respiratory droplets to smaller aerosols. It is important to practice respiratory etiquette, for example coughing into a flexed elbow, and to stay home and self-isolate until you recover if you feel unwell. Most people infected with the virus will experience mild to moderate respiratory illness and will recover without requiring special treatment. Older people and people with underlying medical conditions such as cardiovascular disease, diabetes, chronic respiratory disease, or cancer are more likely to develop serious illnesses. The goal of the research is to propose the best way to prevent and slow down transmission is to be well informed about the disease and how the virus spreads. Protect yourself and others from infection by staying at least 1 meter away from others, wearing a well-fitting mask, and washing your hands or using an alcohol-based rub frequently.

Some reflections will be presented on diabetes mellitus, which is a very common chronic disease in daily life due to different causes where diet and sedentary lifestyle directly influence. Considering these analyzes, the proposal of this work is to ensure that readers are able to know, interpret, disseminate and in many cases recommend preventive measures that help improve the physical and mental health of readers, and citizens, with this it would be achieved the best quality of life in society. The disease flourishes when the pancreas does not secrete enough insulin or when the body does not use the insulin it produces effectively. The effect of uncontrolled diabetes is hyperglycemia or high blood glucose). Over time, this disease seriously damages many organs of the human body, mainly the nervous system and blood vessels. They achieve a healthy body and mind at the present time that humanity is engaged in eradicating the viruses that have affected the world population, which would provide a healthy development for humanity.

Humanity has been on its way accompanied by epidemics, as man has evolved, he has faced different problems that have affected most of society. In the last 50 years, more viruses have appeared that have affected different regions and multiple countries; but one of the most distributed worldwide is COVID-19. The objective is to offer some information related to this pandemic and its evolution in different countries. The bibliographic review method was used even though some bibliographies are very recent, but it has allowed us to know their behavior and follow-up. The results of the countries most affected by this pandemic are shown, where it could be said that Italy has increasingly affected all of them and some countries in Asia, the United States, Latin America, and the Caribbean have been the most affected.

Cardiovascular and renal diseases constitute two pathophysiological contexts of progressive fatal recognitions worldwide and as priorities in terms of health in its entirety. Erythropoietin is a glycoprotein hormone which produces red blood cells, which carry oxygen in the blood.  The objective was to know the most prevalent modifiable risk factors found in arterial hypertension, since this disease is the third cause of death in the world, the bibliographic search and the inductive-deductive method were used. The result was that treatment with recombinant human erythropoietin-stimulating agents is considered effective in improving the management of anemia associated with chronic kidney disease, since it has cardioprotective, renoprotective and neuroprotective functions.
