It sounds strange, but bathing too much is as harmful as being lazy to shower. According to a team of infectious disease experts from Columbia University (USA), too much bathing will make the skin dry and cracked, leading to bacteria that can easily enter the body through these wounds. Experts recommend not bathing more than once a day. 2. Not washing hands before going to the toilet Bacteria aren’t just in the toilet, they’re everywhere. This means that if you don’t wash your hands for a long time, bacteria are also building up on your hands. When going to the toilet, your hands can touch very “private” places, so your hands must be clean. So washing your hands before and after using the toilet is equally important. 3. Use your finger to press the drain button The bathroom is probably the dirtiest place in the house. Studies show that, even 90 minutes after flushing, dozens of bacteria-laden droplets remain on surfaces. Therefore, use knuckles instead of fingertips to press the discharge button. This can be of great help, in case you forget and touch something before washing your hands – you won’t be spreading germs around. 4. Lazy to wash sheets and pillows Sheets and pillows are a haven for dust mites or mold. If not washed regularly, they will become one of the common causes of skin problems. One study found that dust can trigger allergies, causing nasal congestion, swelling, and irritation of the upper respiratory tract. Experts recommend washing sheets and pillows once a week with warm water. 5. Sleeping with a pet Even the best-groomed pets carry a lot of bacteria on their fur. They can even cause plague. 6. Wash your face with soap Some people mistakenly believe that, if you wash your face with soap twice a day, your face will be very clean and acne will be avoided. In fact, soap clogs pores and irritates breakouts. Dermatologists stress that soap was not originally meant for the face. When used, they destroy the protective barrier and disrupt the pH level of the skin.

Disease – The most dangerous enemy: An extremely practical book by two authors Michael T. Osterholm and Mark Olshaker. This is a work written on infectious diseases and pandemics in today’s era from the perspective of epidemiologists, synthesized from the process of observing and studying pandemics, as well as the development of policies. book against prominent modern public health problems. With 21 chapters presented in a fairly brief manner, always focusing on the most dangerous enemies, with a way of exploiting information related to that dangerous enemy with classic questions: Who ( who), What (what), When (when), Where (where), and Why (why) and the word How (how). The authors lead us as detectives investigate a case throughout more than 400 pages of books, by learning about the typical epidemics that have affected humanity throughout history to the present day. such as the Spanish flu pandemic of 1918, the plague in London, the SARS epidemic in Vietnam and Southeast Asian countries with the most urgent risks and challenges, thereby proposing measures that can solve these problems. problems of humanity. Origins of Diseases – Animals, Humans and the Next Global Pandemic: Is a masterpiece that attracts the world’s media by author David Quammen, providing a scientific perspective on pathogens that cause diseases in animals, and sometimes transmitted to humans. In the book, the author weaves a special story, a detective novel with different but also very real killers. They are viruses, bacteria and protozoa that cause disease in animals, but sometimes, they change their target and jump to humans. The emergence of zoonotic diseases – pathogens that reach us from other species – is nothing new but is on the rise, and Quammen seeks to find the reasons behind this phenomenon. the same image in the final chapter of the book: the huge human population, along with the enormous amount of livestock, the destruction of natural habitats, the disrupted ecosystems – things that are absolutely possible. can turn into a debate about nature’s revenge on humanity. Immune system – Discover the body’s self-healing mechanism: In the book Immune system , leading immunologist Daniel M.Davis has likened that, studying the immune system in the human body is like studying the stars and galaxies in our universe. The author gives us an overview of the big picture of the immune system, along with stories about the journey to discover pieces of that picture. The book is divided into two parts. The first part explains the basic concepts of resistance, and tells the journey to explore the cells and complex mechanisms in the immune system. The second part discusses modern research on how different agents affect our immune system. Diagnosis of Covid-19 with Eastern and Western medicine: The book gives readers a first-hand view of the disease by approaching the disease from many aspects, including: clinical features, incubation and disease mechanisms, source and mode of transmission, criteria and diagnostic procedures. diagnosis and progression of the disease worldwide. According to the two authors, the highlight of Western medicine is the treatment with antiviral drugs and antibiotics, immunotherapy drugs, drugs that modulate the intestinal ecosystem, the use of plasma from already healthy patients, the application of Continuous extra-renal dialysis… However, the book also highlights the advantages of Oriental medicine in the way of prevention, diagnosis and recovery, based on the author’s practical experience when working in field hospitals and other medical institutions. Clinical research on oriental medicine. From detailed advice on living habits, herbal remedies combined with acupressure or acupuncture to gentle exercises, all of which help “prevent disease even when there is no disease, support qi to ward off disease”. Guns, Germs and Steel – The Destiny of Human Societies : The work won the Pulitzer Prize. This is a classic book about 13,000 years of human development. The book explains how Eurasian civilizations (including North Africa) survived and conquered other civilizations, while disproving theories of the domination of other civilizations. Eurasian civilization was based on intellectual, moral or genetic superiority. Jared Diamond argues that differences in power and technology between human societies are rooted in environmental differences, in which this difference is magnified. Thereby, he explains why Western Europe, not other civilizations in the Eurasian world like China, became the dominant forces. Although this book is ultimately about history and prehistory, its subject matter is not only of academic value but also of great practical and political importance. The history of interactions between different peoples is what has shaped the modern world through conquest, infectious disease, and genocide. Those conflicts produced lasting effects that, after centuries, are still actively ongoing in some of the world’s most problematic regions today.

TS. Alexandre Yersin born in 1863 in the State of Vaud, Switzerland. At the age of 20, he studied medicine in Lausanne (Switzerland), then continued to study in Marbourg (Germany) and graduated from the University of Paris (France) with a doctorate in medicine. Since 1886, Yersin worked at the Pasteur Institute and collaborated with Dr. Roux to find out the toxin of the diphtheria bacteria. In 1889, Yersin naturalized French. Yersin- the world-famous doctor thanks to the discovery of bacteria that cause plague. A bright future is opening up Young Yersin . However, in addition to his passion for medicine, Yersin has a desire to explore nature. To fulfill his dream of exploring strange lands, he would like to be a doctor on a transport ship floating at sea. In 1892, he went to Nha Trang, Vietnam. The tropical climate is full of mysteries and attractions that make the decision to live, work and stick with this land. Here, he made expeditions to discover new lands. Thanks to these trips, Yersin found Lang Biang Plateau. That was January 1893, he made an expedition that lasted for nearly 7 months. After crossing the rugged mountains and ethnic minority villages, in June 1893 Yersin discovered Lam Vien Plateau (Lang Biang Plateau), 1,500 meters high, today Da Lat city. Yersin wrote in his notebook: “The impression is so profound. Out of the pine forest, I saw right in front of the vast, bare plateau, like the sea was rolling in green waves. The Lam Mountains. Vien with 3 peaks of 2,000 meters, rising from the northwest horizon, creates a majestic backdrop that enhances the magnificence of this region “. In 1897, it was he who proposed to the Governor-General of Indochina, Paul Dumer, to choose this place as the site for the construction of the sanatorium. Then, by a trip to the plateau with the Governor-General of Indochina, he took part in deciding to establish a nursing station on Lang Biang Plateau – the forerunner of Da Lat city later. The first person to find the bacteria that cause the plague In 1894, while preparing to make the next expedition, at the request of the French Government and the Pasteur Institute, Yersin traveled to Hong Kong to study the plague. Here he saw dead bodies of plague dead in the streets, among puddles, in gardens, on moored boats. Yersin has spent most of his life in Vietnam. When Yersin discovered that his colleagues were looking for the plague bacteria in the blood, Yersin said that this is not the right way. According to Yersin, the bacteria must be found in the lymph nodes. With the help of Vigano, an Italian living in Hong Kong, Yersin works in a straw-covered bamboo shack. In order to get the corpses for experimentation, he had to pay money to British sailors who were supposed to bury the bodies. Thanks to that, Yersin was able to enter the body cellar several hours before the body was taken to the cemetery. He had to remove the lime coating the corpse, cut the lymph nodes himself from the corpse and bring it to his laboratory. The microscope shows a multitude of homogeneous images of stick-shaped, two-headed, stick-shaped bacteria. Yersin injected the bacteria into the mouse, twenty-four hours after the mouse died. Other test animals die from two to six days and in cadavers full of lymph nodes. Over a period of seven days, Yersin found the plague bacteria. He sent to the Pasteur Paris Institute a number of fully filled test tubes taken from the sick lymph nodes. When the plague in Hong Kong has calmed down, Yersin returned to France to work with colleagues on the vaccine to prevent it, and the sera (sérum) to treat the plague. When the serum production was completed, Yersin asked to return to Nha Trang to set up a laboratory and build a horse farm in Suoi Dau to produce a lot of serum to prevent patients in neighboring countries. In 1975, the Tenth World Congress of Biology decided to name the plague bacterium “Yersinia-Pestis”. Scientists said that Dr. Yersin was the benefactor of humanity when it was able to prevent the plague at that time. Add more imprints In 1902 – 1904, at the request of Governor-General of Indochina Paul Dumer, Yersin went to Hanoi to establish and run the Indochina Medical and Pharmaceutical School in Hanoi – the first medical training facility of the Indochinese peninsula. built according to the model of the West. Besides medicine, Yersin is passionate about exploring new lands During those difficult early years, Yersin worked actively to found the Medical and Pharmaceutical University and became the first principal of the University (a member of Indochina University in 1906, later to become the University of Indochina). Ha Noi medical university). With his contributions and dedication to the field of medicine, in 1904, Yersin was appointed as a representative of Pasteur Paris Institute in Indochina and Director of Pasteur Institute Saigon and Nha Trang. He also holds many important positions in the health sector. Not only contributing in the medical field, he also has many contributions in the agricultural field. He was the first to import rubber trees from Brazil to plant in Vietnam. Not only importing trees, he also pays special attention to the methods of planting, exploiting and processing rubber to have the highest efficiency. He set up an agrochemical laboratory. Here, the methods of breeding, tapping and coagulating rubber have been studied in a systematic way. Thanks to that, rubber growers in Indochina in the past no longer had to struggle as before. Yersin breathed his last in early 1943. According to his wishes, when he was buried, he was placed on his stomach, his head turned to the sea so that he forever embraced his second home land.
