Prevention
It is important to teach children how to avoid fire and scalding. Firefighters and community leaders often lead such programs in schools and clinics.Smoke alarms installed in homes can reduce deaths resulting from fire by half. Homeowners should change batteries at least once a year and replace smoke alarms every decade. Before fire occurs, a family should practice evacuating the home, and when fire occurs the family must leave the residence immediately (within two minutes). Sources of flame, like matches, should be kept out of childrens reach. Stoves, ovens, space-heaters, and candles must not be left unattended, and flammable objects must be kept at least 30 cm away from open flames. Fire extinguishers should be stored in the kitchen, where most house fires start.To prevent children from getting burned, water temperature must not be set too high when taking baths or washing hands, nonflammable sleepwear should be worn, back burners should be used when cooking something on the stove, and hot foods, drinks, and irons should be kept away from the edge of counter and table. Oven mitts and potholders must be used in handling hot containers. Care should be taken when taking hot foods out of microwave ovens, and covers should be opened gently to reduce the risk of steam burns. Treatment
The most important first action is to stop the burning process. The source of the burn should promptly be removed (or the patient removed from the source).
Coronavirus diseases are caused by viruses in the coronavirus subfamily, a group of related RNA viruses that cause diseases in mammals and birds. In humans and birds, the group of viruses cause respiratory tract infections that can range from mild to lethal. Mild illnesses in humans include some cases of the common cold (which is also caused by other viruses, predominantly rhinoviruses), while more lethal varieties can cause SARS, MERS and COVID-19. As of 2021, 45 species are registered as coronaviruses, whilst 11 diseases have been identified, as listed below. Coronaviruses are known for their shape resembling a stellar corona, such as that of the Sun visible during a total solar eclipse; corona is derived from the Latin word corōna, meaning garland, wreath, crown. It was coined by Tony Waterson (professor of virology at St Thomas Hospital) in a meeting with his colleagues June Almeida and David Tyrrell, the founding fathers of coronavirus studies, and was first used in a Nature article in 1968, with approval by the International Committee for the Nomenclature of Viruses three years later.The first coronavirus disease was discovered in the late 1920s, however, the most recent common ancestor of coronaviruses is estimated to have existed as recently as 8000 BCE. Human coronaviruses were discovered in the 1960s, through a variety of experiments in the United States and the United Kingdom. A common origin in human coronaviruses is bats. List
