Isolation (health care) in the context of Isolation ward

In public health, contact tracing is the process of identifying people who may have been exposed to an infected person ("contacts") and subsequent collection of further data to assess transmission. By tracing the contacts of infected individuals, testing them for infection, and isolating or treating the infected, this public health tool aims to reduce infections in the population. In addition to infection control, contact tracing serves as a means to identify high-risk and medically vulnerable populations who might be exposed to infection and facilitate appropriate medical care. In doing so, public health officials utilize contact tracing to conduct disease surveillance and prevent outbreaks. In cases of diseases of uncertain infectious potential, contact tracing is also sometimes performed to learn about disease characteristics, including infectiousness. Contact tracing is not always the most efficient method of addressing infectious disease. In areas of high disease prevalence, screening or focused testing may be more cost-effective.

The goals of contact tracing include:

Negative room pressure is an isolation technique used in hospitals and medical centers to prevent cross-contamination from room to room. It includes a ventilation that generates negative pressure (pressure lower than that of the surroundings) to allow air to flow into the isolation room but not escape from the room, as air will naturally flow from areas with higher pressure to areas with lower pressure, thereby preventing contaminated air from escaping the room. This technique is used to isolate patients with airborne contagious diseases such as influenza (flu), measles, chickenpox, tuberculosis (TB), severe acute respiratory syndrome (SARS-CoV), Middle East respiratory syndrome (MERS-CoV), and coronavirus disease 2019 (COVID-19).

A quarantine is a restriction on the movement of people, animals, and goods which is intended to prevent the spread of disease or pests. It is often used in connection to disease and illness, preventing the movement of those who may have been exposed to a communicable disease, yet do not have a confirmed medical diagnosis. It is distinct from medical isolation, in which those confirmed to be infected with a communicable disease are isolated from the healthy population.

The concept of quarantine is known to have been practised through history in various places. Notable quarantines in modern history include the village of Eyam in 1665 during the bubonic plague outbreak in England; East Samoa during the 1918 flu pandemic; the Diphtheria outbreak during the 1925 serum run to Nome, the 1972 Yugoslav smallpox outbreak, the SARS pandemic, the Ebola pandemic and extensive quarantines applied throughout the world during the COVID-19 pandemic since 2020.

In public health, social distancing, also called physical distancing, is a set of non-pharmaceutical interventions or measures intended to prevent the spread of a contagious disease by maintaining a physical distance between people and reducing the number of times people come into close contact with each other. It usually involves keeping a certain distance from others (the distance specified differs from country to country and can change with time) and avoiding gathering together in larger groups.

By minimising the probability that a given uninfected person will come into physical contact with an infected person, the disease transmission can be suppressed, resulting in fewer deaths. The measures may be used in combination with other public health recommendations, such as good respiratory hygiene, use of face masks when necessary, and hand washing. To slow down the spread of infectious diseases and avoid overburdening healthcare systems, particularly during a pandemic, several social-distancing measures have been used, including the closing of schools and workplaces, isolation, quarantine, restricting the movement of people and the cancellation of mass gatherings. Drawbacks of social distancing can include loneliness, reduced productivity and the loss of other benefits associated with human interaction.

HIStory: Past, Present and Future, Book I (stylized as HIStory - PAST, PRESENT AND FUTURE - BOOK I on streaming platforms), often referred to simply as HIStory, is a double album by the American singer-songwriter Michael Jackson, released on June 20, 1995. It consists of the greatest hits album, HIStory Begins, in addition to his ninth studio album, HIStory Continues. It was Jackson's fifth album released through Epic Records, and the first on his label MJJ Productions. The album includes appearances by Janet Jackson, Shaquille O'Neal, Slash, and the Notorious B.I.G. Its genres span pop, R&B, and hip hop with elements of hard rock and funk rock. Lyrical themes include environmental awareness, isolation, greed, and injustice.

Several of the songs on HIStory Continues pertain to the child sexual abuse allegations made against Jackson in 1993 and Jackson's perceived mistreatment by the media. Singles included the protest songs "Earth Song" and "They Don't Care About Us", the latter of which drew accusations of antisemitism. Jackson vehemently denied these accusations. Jackson embarked on the HIStory World Tour, which was his third and final concert tour as a solo artist. The tour grossed $165 million, making it the highest-grossing solo concert tour of the 1990s.

The COVID-19 pandemic in Nepal was part of the worldwide pandemic of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The first case in Nepal was confirmed on 23 January 2020 when a 31-year-old student, who had returned to Kathmandu from Wuhan on 9 January, tested positive. It was also the first recorded case of COVID-19 in South Asia. Nepal's first case of local transmission was confirmed on 4 April in Kailali District. The first death occurred on 14 May. A country-wide lockdown came into effect on 24 March 2020, and ended on 21 July 2020. As of 26 July 2022, the Ministry of Health and Population (MoHP) has confirmed a total of 984,475 cases, 968,802 recoveries, and 11,959 deaths in the country. In the meantime, 5,804,358 real-time RT-PCR (RT-qPCR) tests have been performed in 40 laboratories across the country. The viral disease has been detected in all provinces and districts of the country, with Bagmati Province and Kathmandu being the worst hit province and district respectively. As for Nepalese abroad, as of 26 July 2020, the Non-Resident Nepali Association has reported a total of 12,667 confirmed cases, 16,190 recoveries, and 161 deaths across 35 countries.

From January to March, Nepal took steps to prevent a widespread outbreak of the disease while preparing for it by procuring essential supplies, equipment and medicine, upgrading health infrastructure, training medical personnel, and spreading public awareness. Starting in mid-January, Nepal established health-desks at Tribhuvan International Airport as well as at border checkpoints with India. Land borders with India as well as China were later completely sealed off, and all international flights were suspended. All academic examinations were cancelled, and schools and colleges were closed. Quarantine centres and temporary hospitals are being set up across the country. Laboratory facilities are being upgraded and expanded. Hospitals have been setting up ICU units and isolation beds. The SAARC countries have pledged to cooperate in controlling the disease in the region. India, the United States and Germany increased their support to Nepali health sectors.
