In hospitals, physicians will sometimes use antibiotics to treatsecondary bacterial infections, which can be a complication of COVID-19 inseverely ill patients. They should only be used as directed by a physician totreat a bacterial infection. For those who need it, doctors will suggest treatments for COVID-19 based on the severity of the disease and the risk of it getting worse.
Helping children cope with stress during COVID-19 outbreak
In rare situations, children can develop a severe inflammatory syndrome a few weeks after infection. We must remember that behind every health figure is a person, a family – a life. With good data we can ensure no one dies from a preventable, treatable illness.
The impact of health on all aspects of society – from economic activity to social and environmental factors – has never been clearer. Once created, preliminary country estimates will be shared through the World Health Data Hub country portal for official consultation. Country consultation is a cornerstone of WHO’s data principles and commitment to uphold Member States’ trust in data. The country portal will provide a https://chicken-road-game-download.net/ secure environment for Member States and WHO to exchange data and information across all three levels as part of the estimate verification and consultation process. Currently, WHO data engineers are leveraging state-of-the-art data pipelining services including Azure Data Factory to ingest and harmonize data from various sources into a modern Data Lake project repository. After data is ingested, WHO data scientists and Technical Advisory Group members are then able to build statistical and machine learning models together in R and Python in a cloud-based collaborative research environment.
Home care for COVID-19: Guide for family and caregivers
- People over age 60 and those with existing medical conditions have a higher risk of getting seriously ill.
- It is important to stay up to date with local guidelines and recommendations provided by your local health authority.
- To overcome these challenges, many countries have turned to excess mortality as a more accurate measure of the true impact of the pandemic.
- Without timely, reliable and actionable data we cannot accurately measure progress towards the health-related SDGs or WHO’s Triple Billion targets.
- This page includes advice from WHO on ways to protect yourself and prevent the spread of COVID-19.
- Quarantine means that you remain separated fromothers because you have been exposed to the virus and you may be infected andcan take place in a designated facility or at home.
There are two main types of tests that can confirm whether youare infected with SARS-CoV-2, the virus that causes COVID-19. Molecular tests,such as polymerase chain reaction (PCR), are the most accurate tests fordiagnosing SARS-CoV-2 infection. Molecular tests detect virus in the sample byamplifying viral genetic material to detectable levels. Rapid antigen tests(sometimes known as rapid diagnostic tests or RDTs) detect viral proteins(known as antigens). RDTs are a simpler and faster option than molecular testsand are available for testing by trained operators or by the individualthemselves (sometimes called self-tests).
If you have been exposed to someone with COVID-19, you may become infected, even if you feel well. Individuals with signs and symptoms suggestive of COVID-19 or those who test positive for the virus should wear a mask when interacting with others in or outside of one’s household or sharing space with others. Although WHO announced the end of the emergency phase of COVID-19 in May 2023, the Organization continues to coordinate the global response. Anyone can get sick with COVID-19 and become seriously ill or die, but most people will recover without treatment.
At the start of the pandemic, 15% of people were thought to become seriously unwell and require hospital treatment and oxygen. More recent estimates suggest that hospitalization is required in around 3% of people with COVID-19. This is partly due to immunization, partly due to changes in the virus (especially the Omicron variants), and partly due to the availability of targeted medical treatments. People with severe disease and those needing hospital treatment should receive treatment as soon as possible. For countries with limited capacity to conduct real-time comparative analysis of observed and expected deaths, health estimates are an important in-filling mechanism. They can be calculated using a variety of statistical methods, from a minimalist approach to expert and statistical data synthesis.
According to WHO’s World Health Statistics 2020 report, for almost one-fifth of countries over half of the SDG indicators lack recent, primary data. The availability of data also varies widely by income group and by indicator. For 2020, excess mortality attributable to COVID-19 is defined as the difference between the total observed deaths for the year and those expected in the absence of COVID-19. The measure cannot be determined for all countries due to data gaps within some countries. Countries also use different processes to test and report COVID-19 deaths, making comparisons difficult. To overcome these challenges, many countries have turned to excess mortality as a more accurate measure of the true impact of the pandemic.
Homecare for people with COVID-19: Members of the household
The COVID TAG is comprised of leading demographers, epidemiologists, data and social scientists and statisticians from a range of backgrounds and geographies. The time from exposure to COVID-19 to the moment when symptomsbegin is, on average, 5–6 days and can range from 1–14 days. This is why peoplewho have been exposed to the virus are advised to remain at home and stay awayfrom others in order to prevent the spread of the virus. Some people who have had COVID-19, whether they have needed hospitalization or not, continue to experience symptoms, including fatigue, respiratory and neurological symptoms. These long-term effects are called post COVID-19 condition (also called long COVID).

- The model predicts the number of total deaths for the year 2020 conditional on the population size and expected deaths for the year as well as a predicted mortality rate parameter.
- Rapid antigen tests(sometimes known as rapid diagnostic tests or RDTs) detect viral proteins(known as antigens).
- Both isolation and quarantine are methods of preventing thespread of COVID-19.
- Samples for both types of tests are collected from thenose and/or throat with a swab.
- Individuals with signs and symptoms suggestive of COVID-19 or those who test positive for the virus should wear a mask when interacting with others in or outside of one’s household or sharing space with others.
Stay aware of the latest COVID-19 information by regularly checking updates from WHO in addition to national and local public health authorities. WHO first learned of this new virus on 31 December 2019,following a report of a cluster of cases of so-called viral pneumonia in Wuhan,People’s Republic of China. They should follow local guidance on vaccination and ways to protect themselves against COVID-19.
If you have been vaccinated, many antibody tests arenot able to distinguish between whether you were previously infected or havebeen vaccinated (or both), so in such situations you will test positive ineither case. WHO is actively engaging with Member States to strengthen health information systems, particularly civil registration and vital statistics (CRVS), and improve data availability and quality. This includes targeted interventions to address the weakest areas identified by the SCORE (Survey, Count, Optimize, Review, Enable) global report, 2020, which showed for example that only 27% of countries have sustainable capacity to survey public health threats. For those with COVID-19 who are at high risk of severe illness (see question below), WHO has made recommendations on which drug treatments are effective in improving outcomes and preventing hospital admissions. People over age 60 and those with existing medical conditions have a higher risk of getting seriously ill. These conditions include high blood pressure, diabetes, obesity, immunosuppression including HIV, cancer and pregnancy.
In March 2023, WHO updated its recommendations on primary series vaccination (two doses of any vaccine) as well as the need for booster doses. These recommendations are time-limited and can change at any time depending on how the SARS-CoV-2 virus is circulating in your area or country. It is important to stay up to date with local guidelines and recommendations provided by your local health authority.
People who have pre-existing health problems are at higher risk when they have COVID-19; they should seek medical help early if worried about their condition. These include people taking immunosuppressive medication; those with chronic heart, lung, liver or rheumatological problems; those with HIV, diabetes, cancer. The COVID TAG considered several statistical models and after assessing performance, interpretability and extensibility proposed a negative binomial regression model. The model predicts the number of total deaths for the year 2020 conditional on the population size and expected deaths for the year as well as a predicted mortality rate parameter. This rate parameter captures both the direct and indirect impacts of COVID-19 and is modelled using country-specific variables.
Isolation is used for people with COVID-19 symptoms or who have testedpositive for the virus. Being in isolation means being separated from otherpeople, ideally in a medical facility where you can receive clinical care. Ifisolation in a medical facility is not possible and you are not in a high-riskgroup for developing severe disease, isolation can take place at home. If you areinfected and do not develop symptoms, you should remain in isolation for 5 daysfrom the time you test positive. You can be discharged from isolation early ifyou test negative on a rapid antigen test. It is also important to be vigilant in recognizing people with severe disease and those needing hospital treatment so that they are treated early.
Clinical management of COVID-19: living guideline, June 2025
Excess mortality is defined as the difference in the total number of deaths in a crisis compared to those expected under normal conditions. COVID-19 excess mortality accounts for both the total number of deaths directly attributed to the virus as well as the indirect impact, such as disruption to essential health services or travel disruptions. With the latest COVID-19 deaths reported to WHO now exceeding 3.4 million, based on the excess mortality estimates produced for 2020, we are likely facing a significant undercount of total deaths directly and indirectly attributed to COVID-19. Without timely, reliable and actionable data we cannot accurately measure progress towards the health-related SDGs or WHO’s Triple Billion targets. Moreover, we cannot accurately measure the impact of the COVID-19 pandemic to better inform public policy and prepare for future health emergencies.
The consequences of severe COVID-19 include death, respiratory failure, sepsis, thromboembolism (blood clots), and multiorgan failure, including injury of the heart, liver or kidneys. While a person is waiting for test results, they should preferably wear a mask when interacting with others in or outside of their household or sharing space with others. As testing rates fall, it is more difficult to know how many people have COVID-19 and do not seek any treatment.
