A high-risk individual or high-risk person or high-risk population is a human being or beings living with an increased risk for severe illness due to age, medical condition, pregnancy/post-pregnant conditions, geographical location, or a combination of these risk factors. [1]
High-risk people can be of any age. [2] High-risk populations are vulnerable to serious illness. [3] Globally, societal factors including limited access to healthcare and inadequate hygiene facilities can result in high-risk individuals. [3] [4] [5] Access to proper healthcare is essential to the health and treatment of high-risk individuals, particularly high-risk mothers and infants. [3] High-risk individuals can require long-term care. [3]
In immunology, a person qualifies as a high-risk individual if their immune system is compromised or suppressed whether due to disease, cancer, chronic conditions, prescription medications, or recent surgical procedures. [6] [7] [8] High-risk people are more susceptible to hospitalization and death from the Coronavirus disease 2019. [9] The Centers for Disease Control and Prevention (CDC) recommends high-risk persons get the COVID-19 vaccine. [10] [9]
In psychiatry, a high-risk individual is a patient who engages in high-risk behaviors. [11] In addiction treatment lexicon, a high-risk person refers to a person with a high likelihood of addiction and/or high likelihood of relapse. [12]
Some factors that have been cited in the United States as defining high-risk individuals for suffering the more serious symptoms of COVID-19 include: [13] [14]
The DPT vaccine or DTP vaccine is a class of combination vaccines against three infectious diseases in humans: diphtheria, pertussis, and tetanus. The vaccine components include diphtheria and tetanus toxoids and either killed whole cells of the bacterium that causes pertussis or pertussis antigens. The term toxoid refers to vaccines which use an inactivated toxin produced by the pathogen which they are targeted against in order to generate an immune response. In this way, the toxoid vaccine generates an immune response which is targeted against the toxin which is produced by the pathogen and causes disease, rather than a vaccine which is targeted against the pathogen itself. The whole cells or antigens will be depicted as either "DTwP" or "DTaP", where the lower-case "w" indicates whole-cell inactivated pertussis and the lower-case "a" stands for "acellular". In comparison to alternative vaccine types, such as live attenuated vaccines, the DTP vaccine does not contain the pathogen itself, but rather uses inactivated toxoid to generate an immune response; therefore, there is not a risk of use in populations that are immune compromised since there is not any known risk of causing the disease itself. As a result, the DTP vaccine is considered a safe vaccine to use in anyone and it generates a much more targeted immune response specific for the pathogen of interest. However, booster doses are recommended every ten years to maintain immune protection against these pathogens.
Oseltamivir, sold under the brand name Tamiflu, is an antiviral medication used to treat and prevent influenza A and influenza B, viruses that cause the flu. Many medical organizations recommend it in people who have complications or are at high risk of complications within 48 hours of first symptoms of infection. They recommend it to prevent infection in those at high risk, but not the general population. The Centers for Disease Control and Prevention (CDC) recommends that clinicians use their discretion to treat those at lower risk who present within 48 hours of first symptoms of infection. It is taken by mouth, either as a pill or liquid.
Preventive healthcare, or prophylaxis is the application of healthcare measures to prevent diseases. Disease and disability are affected by environmental factors, genetic predisposition, disease agents, and lifestyle choices, and are dynamic processes which begin before individuals realize they are affected. Disease prevention relies on anticipatory actions that can be categorized as primal, primary, secondary, and tertiary prevention.
Influenza vaccines, also known as flu shots, are vaccines that protect against infection by influenza viruses. New versions of the vaccines are developed twice a year, as the influenza virus rapidly changes. While their effectiveness varies from year to year, most provide modest to high protection against influenza. The United States Centers for Disease Control and Prevention (CDC) estimates that vaccination against influenza reduces sickness, medical visits, hospitalizations, and deaths. Immunized workers who do catch the flu return to work half a day sooner on average. Vaccine effectiveness in those over 65 years old remains uncertain due to a lack of high-quality research.
Sexual and reproductive health (SRH) is a field of research, health care, and social activism that explores the health of an individual's reproductive system and sexual well-being during all stages of their life.
A health professional, healthcare professional, or healthcare worker is a provider of health care treatment and advice based on formal training and experience. The field includes those who work as a nurse, physician, physician assistant, registered dietitian, veterinarian, veterinary technician, optometrist, pharmacist, pharmacy technician, medical assistant, physical therapist, occupational therapist, dentist, midwife, psychologist, or who perform services in allied health professions. Experts in public health and community health are also health professionals.
Varicella vaccine, also known as chickenpox vaccine, is a vaccine that protects against chickenpox. One dose of vaccine prevents 95% of moderate disease and 100% of severe disease. Two doses of vaccine are more effective than one. If given to those who are not immune within five days of exposure to chickenpox it prevents most cases of disease. Vaccinating a large portion of the population also protects those who are not vaccinated. It is given by injection just under the skin. Another vaccine, known as zoster vaccine, is used to prevent diseases caused by the same virus – the varicella zoster virus.
In health care facilities, isolation represents one of several measures that can be taken to implement in infection control: the prevention of communicable diseases from being transmitted from a patient to other patients, health care workers, and visitors, or from outsiders to a particular patient. Various forms of isolation exist, in some of which contact procedures are modified, and others in which the patient is kept away from all other people. In a system devised, and periodically revised, by the U.S. Centers for Disease Control and Prevention (CDC), various levels of patient isolation comprise application of one or more formally described "precaution".
Chickenpox, or chicken pox, also known as varicella, is a highly contagious, vaccine-preventable disease caused by the initial infection with varicella zoster virus (VZV), a member of the herpesvirus family. The disease results in a characteristic skin rash that forms small, itchy blisters, which eventually scab over. It usually starts on the chest, back, and face. It then spreads to the rest of the body. The rash and other symptoms, such as fever, tiredness, and headaches, usually last five to seven days. Complications may occasionally include pneumonia, inflammation of the brain, and bacterial skin infections. The disease is usually more severe in adults than in children.
Refugee health is the field of study on the health effects experienced by people who have been displaced into another country or even to another part of the world, as a result of unsafe circumstances such as war or persecution. Displaced populations' health is mainly affected by infectious disease, mental health, and chronic diseases that are uncommon in the country in which they eventually settle. Refugee health status is largely due to factors such as the migrant's geographic origin, conditions of refugee camps or urban settings where they lived, and personal, physical, and psychological conditions of the migrant, either pre-existing or acquired while traveling from their homeland to a camp or eventually to their new home.
Discrimination against people with HIV/AIDS or serophobia is the prejudice, fear, rejection, and stigmatization of people with HIV/AIDS. Marginalized, at-risk groups such as members of the LGBTQ+ community, intravenous drug users, and sex workers are most vulnerable to facing HIV/AIDS discrimination. The consequences of societal stigma against PLHIV are quite severe, as HIV/AIDS discrimination actively hinders access to HIV/AIDS screening and care around the world. Moreover, these negative stigmas become used against members of the LGBTQ+ community in the form of stereotypes held by physicians.
Lesotho's Human development index value for 2018 was 0.518—which put the country in the low human development category—positioning it at 164 out of 189 countries and territories. Health care services in Lesotho are delivered primarily by the government and the Christian Health Association of Lesotho. Access to health services is difficult for many people, especially in rural areas. The country's health system is challenged by the relentless increase of the burden of disease brought about by AIDS, and a lack of expertise and human resources. Serious emergencies are often referred to neighbouring South Africa. The largest contribution to mortality in Lesotho are communicable diseases, maternal, perinatal and nutritional conditions.
Infectious diseases within American correctional settings are a concern within the public health sector. The corrections population is susceptible to infectious diseases through exposure to blood and other bodily fluids, drug injection, poor health care, prison overcrowding, demographics, security issues, lack of community support for rehabilitation programs, and high-risk behaviors. The spread of infectious diseases, such as HIV and other sexually transmitted diseases, hepatitis C (HCV), hepatitis B (HBV), and tuberculosis, result largely from needle-sharing, drug use, and consensual and non-consensual sex among prisoners. HIV and hepatitis C need specific attention because of the specific public health concerns and issues they raise.
This article summarizes healthcare in Texas. In 2022, the United Healthcare Foundation ranked Texas as the 38th healthiest state in the United States. Obesity, excessive drinking, maternal mortality, infant mortality, vaccinations, mental health, and limited access to healthcare are among the major public health issues facing Texas.
Coronavirus disease 2019 (COVID-19) is a contagious disease caused by the virus severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The first known case was identified in Wuhan, China, in December 2019. The disease quickly spread worldwide, resulting in the COVID-19 pandemic.
An N95 filtering facepiece respirator, commonly abbreviated N95 respirator, is a particulate-filtering facepiece respirator that meets the U.S. National Institute for Occupational Safety and Health (NIOSH) N95 classification of air filtration, meaning that it filters at least 95% of airborne particles that have a mass median aerodynamic diameter of 0.3 micrometers. This standard does not require that the respirator be resistant to oil; another standard, P95, adds that requirement. The N95 type is the most common particulate-filtering facepiece respirator. It is an example of a mechanical filter respirator, which provides protection against particulates but not against gases or vapors. An authentic N95 respirator is marked with the text "NIOSH" or the NIOSH logo, the filter class ("N95"), a "TC" approval number of the form XXX-XXXX, the approval number must be listed on the NIOSH Certified Equipment List (CEL) or the NIOSH Trusted-Source page, and it must have headbands instead of ear loops.
Hazard controls for COVID-19 in workplaces are the application of occupational safety and health methodologies for hazard controls to the prevention of COVID-19. Vaccination is the most effective way to protect against severe illness or death from COVID-19. Multiple layers of controls are recommended, including measures such as remote work and flextime, increased ventilation, personal protective equipment (PPE) and face coverings, social distancing, and enhanced cleaning programs.
The COVID-19 pandemic has impacted the mental health of people across the globe. The pandemic has caused widespread anxiety, depression, and post-traumatic stress disorder symptoms. According to the UN health agency WHO, in the first year of the COVID-19 pandemic, prevalence of common mental health conditions, such as depression and anxiety, went up by more than 25 percent. The pandemic has damaged social relationships, trust in institutions and in other people, has caused changes in work and income, and has imposed a substantial burden of anxiety and worry on the population. Women and young people, especially LGBTQ youth, face the greatest risk of depression and anxiety.
In epidemiology, a non-pharmaceutical intervention (NPI) is any method used to reduce the spread of an epidemic disease without requiring pharmaceutical drug treatments. Examples of non-pharmaceutical interventions that reduce the spread of infectious diseases include wearing a face mask and staying away from sick people.
People with disabilities are at greater risk of contracting COVID-19 and have higher rates of mortality than non-disabled populations. This is especially true for people with intellectual and developmental disabilities, individuals who reside in care facilities, and women with disabilities. People with disabilities are at greater risk of experiencing mental health issues related to the pandemic, such as feelings of loneliness and isolation. They may be at greater risk of domestic violence and abuse during the pandemic. People with disabilities are more likely to experience unemployment as a result of the pandemic and may require changes to the types of accommodations they require for work. Children with disabilities are experiencing disruptions to their educational programming. Remote learning poses a host of challenges for children with disabilities, including disruptions to physical and occupational therapies and access to assistive technologies.
