The COVID-19 pandemic has had many impacts on global health beyond those caused by the COVID-19 disease itself. It has led to a reduction in hospital visits for other reasons. There have been 38 per cent fewer hospital visits for heart attack symptoms in the United States and 40 per cent fewer in Spain. [1] The head of cardiology at the University of Arizona said, "My worry is some of these people are dying at home because they're too scared to go to the hospital." [2] There is also concern that people with strokes and appendicitis are not seeking timely treatment. [2] Shortages of medical supplies have impacted people with various conditions. [3]
In several countries there has been a marked reduction of spread of sexually transmitted infections, including HIV/AIDS, attributable to COVID-19 quarantines, social distancing measures, and recommendations to not engage in casual sex. [4] [5] [6] Similarly, in some places, rates of transmission of influenza and other respiratory viruses significantly decreased during the pandemic. [7] [8] [9]
The pandemic has also negatively impacted mental health globally, including increased loneliness resulting from social distancing [10] and depression and domestic violence from lockdowns. [11] As of June 2020, 40% of U.S. adults were experiencing adverse mental health symptoms, with 11% having seriously considered to attempt suicide. [12] The research data suggest that the pandemic has negative effects on both weight loss and food health monitoring but the effects were short lived results. [13]
Paying attention and taking measures to prevent mental health problems and post-traumatic stress syndrome, particularly in women, is already a need. [14]

The COVID-19 pandemic has impacted the mental health of people across the globe. [15] [16] The pandemic has caused widespread anxiety, depression, and post-traumatic stress disorder symptoms. [17] [18] 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. [19] [20] 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. [21] Women and young people face the greatest risk of depression and anxiety. [16] [18]
COVID-19 triggered issues caused by substance use disorders (SUDs). The pandemic disproportionately affects people with SUDs. [22] The health consequences of SUDs (for example, cardiovascular diseases, respiratory diseases, type 2 diabetes, immunosuppression and central nervous system depression, and psychiatric disorders), and the associated environmental challenges (such as housing instability, unemployment, and criminal justice involvement), are associated with an increased risk for contracting COVID-19. Confinement rules, as well as unemployment and fiscal austerity measures during and following the pandemic period, can also affect the illicit drug market and patterns of use among consumers of illicit drugs drastically.
Mitigation measures (i.e. physical distancing, quarantine, and isolation) can worsen loneliness, mental health symptoms, withdrawal symptoms, and psychological trauma.UNICEF estimates that 117 million children across 37 countries may not receive their immunizations in time to prevent a measles outbreak. Pediatricians in the United States are worried about childhood vaccination rates. In April, the CDC reported that 400,000 fewer doses of measles vaccine were ordered in 2020 compared to the same time last year. [23]
Although it is highly unlikely that COVID-19 can be transmitted by mosquitoes, [24] the pandemic nevertheless has a large impact on the control of mosquito-borne diseases such as malaria or dengue fever. Reasons are disruptions in medical supply chains, patients avoiding hospitals, and halted mosquito control campaigns such as removal of breeding sites or distribution of insecticide treated bed nets. [25] [26] [27]
The United States, in particular, saw a 40 percent increase in maternal mortality in 2021, before returning to rates similar to prepandemic levels in 2022. Pregnancy-related conditions such as increased abdominal pressure and propensity for blood clots interacted negatively with SARS-CoV-2 infection, while viral damage to the placenta led to increased risk of dangerous conditions such as pre-eclampsia. Racial disparities were particularly acute, with Black women dying at 2.6 times the rate of white women and Native American and Alaska Native women dying at double the rate of white women in pregnancies from 2020 to 2021. [28]
Millions of Americans lost their health insurance after losing their jobs. [29] [30] [31] [32] The Independent reported that Families USA "found that the spike in uninsured Americans – adding to an estimated 84 million people who are already uninsured or underinsured – is 39 per cent higher than any previous annual increase, including the most recent surge at the height of the recession between 2008 and 2009 when nearly 4 million non-elderly Americans lost insurance." [33]
In late 2022, during the first Northern Hemisphere autumn and winter seasons following the widespread relaxation of global public health measures, North America and Europe experienced a surge in respiratory viruses and coinfections in both adults and children. This formed the beginnings of the 2022–2023 pediatric care crisis and what some experts have termed a "tripledemic" of seasonal influenza, Respiratory Syncytial Virus (RSV), and SARS-CoV-2 throughout North America. [34] [35] In the United Kingdom, pediatric infections also began to spike beyond pre-pandemic levels, albeit with different illnesses, such as Group A streptococcal infection and scarlet fever. [36] As of mid-December 2022, 19 children in the UK had died due to Strep A and the wave of infections had begun to spread into North America and Mainland Europe. [37] [38]
Populations had been exposed to these diseases lower-than-usual rates while masks were worn and social distancing was practiced, thus exhibiting weakened immune responses. [39] Medical professionals have also posited that, since most children have had one or more SARS-CoV-2 infections by late 2022, COVID-19 may have affected children's immune systems in yet-to-be-determined ways. [40] Research demonstrates patients infected with influenza as well as Covid are over twice as likely to die as patients with only Covid. The general public has been urged to get Influenza vaccination as well as Covid vaccination. [41]
UNFPA recommends that governments maintain sexual and reproductive health and rights (SRHR) information and services, protect health workers and limit spread of COVID-19. This includes a comprehensive approach to SRHR information and services encompassing antenatal care (ANC), care during childbirth, postnatal care (PNC), contraception, safe abortion care, prevention, testing and treatment of HIV, where relevant, as well as sexually transmitted infections (STI), detection and treatment of GBV, and sexual health services and information. [42]
A pandemic is an epidemic of an infectious disease that has spread across a large region, for instance multiple continents or worldwide, affecting a substantial number of individuals. Widespread endemic diseases with a stable number of infected individuals such as recurrences of seasonal influenza are generally excluded as they occur simultaneously in large regions of the globe rather than being spread worldwide.
The 1918–1920 flu pandemic, also known as the Great Influenza epidemic or by the common misnomer Spanish flu, was an exceptionally deadly global influenza pandemic caused by the H1N1 influenza A virus. The earliest documented case was March 1918 in the state of Kansas in the United States, with further cases recorded in France, Germany and the United Kingdom in April. Two years later, nearly a third of the global population, or an estimated 500 million people, had been infected in four successive waves. Estimates of deaths range from 17 million to 50 million, and possibly as high as 100 million, making it one of the deadliest pandemics in history.
Influenza, commonly known as "the flu", is an infectious disease caused by influenza viruses. Symptoms range from mild to severe and often include fever, runny nose, sore throat, muscle pain, headache, coughing, and fatigue. These symptoms begin from one to four days after exposure to the virus and last for about 2–8 days. Diarrhea and vomiting can occur, particularly in children. Influenza may progress to pneumonia, which can be caused by the virus or by a subsequent bacterial infection. Other complications of infection include acute respiratory distress syndrome, meningitis, encephalitis, and worsening of pre-existing health problems such as asthma and cardiovascular disease.
Influenza-like illness (ILI), also known as flu-like syndrome or flu-like symptoms, is a medical diagnosis of possible influenza or other illness causing a set of common symptoms. These include fever, shivering, chills, malaise, dry cough, loss of appetite, body aches, and nausea, sneezing typically in connection with a sudden onset of illness. In most cases, the symptoms are caused by cytokines released by immune system activation, and are thus relatively non-specific.
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 and avoiding gathering together in large groups.
The COVID-19 pandemic, also known as the coronavirus pandemic, is a global pandemic of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The novel virus was first identified in an outbreak in the Chinese city of Wuhan in December 2019. Attempts to contain it there failed, allowing the virus to spread to other areas of Asia and later worldwide in 2020. The World Health Organization (WHO) declared the outbreak a public health emergency of international concern (PHEIC) on 30 January 2020. The WHO ended its PHEIC declaration on 5 May 2023. As of 16 October 2023, the pandemic had caused 771,190,439 cases and 6,961,001 confirmed deaths, ranking it fifth in the deadliest epidemics and pandemics in history.
Coronavirus disease 2019 (COVID-19) is a contagious disease caused by the virus 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.

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 face the greatest risk of depression and anxiety.
The symptoms of COVID-19 are variable depending on the type of variant contracted, ranging from mild symptoms to a potentially fatal illness. Common symptoms include coughing, fever, loss of smell (anosmia) and taste (ageusia), with less common ones including headaches, nasal congestion and runny nose, muscle pain, sore throat, diarrhea, eye irritation, and toes swelling or turning purple, and in moderate to severe cases, breathing difficulties. People with the COVID-19 infection may have different symptoms, and their symptoms may change over time. Three common clusters of symptoms have been identified: one respiratory symptom cluster with cough, sputum, shortness of breath, and fever; a musculoskeletal symptom cluster with muscle and joint pain, headache, and fatigue; and a cluster of digestive symptoms with abdominal pain, vomiting, and diarrhea. In people without prior ear, nose, or throat disorders, loss of taste combined with loss of smell is associated with COVID-19 and is reported in as many as 88% of symptomatic cases.
The COVID-19 pandemic has impacted healthcare workers physically and psychologically. Healthcare workers are more vulnerable to COVID-19 infection than the general population due to frequent contact with infected individuals. Healthcare workers have been required to work under stressful conditions without proper protective equipment, and make difficult decisions involving ethical implications. Health and social systems across the globe are struggling to cope. The situation is especially challenging in humanitarian, fragile and low-income country contexts, where health and social systems are already weak. Services to provide sexual and reproductive health care risk being sidelined, which will lead to higher maternal mortality and morbidity.
Although several medications have been approved in different countries as of April 2022, not all countries have these medications. Patients with mild to moderate symptoms who are in the risk groups can take nirmatrelvir/ritonavir or remdesivir, either of which reduces the risk of serious illness or hospitalization. In the US, the Biden Administration COVID-19 action plan includes the Test to Treat initiative, where people can go to a pharmacy, take a COVID test, and immediately receive free Paxlovid if they test positive.
A systematic review notes that children with COVID-19 have milder effects and better prognoses than adults. However, children are susceptible to "multisystem inflammatory syndrome in children" (MIS-C), a rare but life-threatening systemic illness involving persistent fever and extreme inflammation following exposure to the SARS-CoV-2 virus.
Viral interference, also known as superinfection resistance, is the inhibition of viral reproduction caused by previous exposure of cells to another virus. The exact mechanism for viral interference is unknown. Factors that have been implicated are the generation of interferons by infected cells, and the occupation or down-modulation of cellular receptors.
Long COVID or long-haul COVID is a group of health problems persisting or developing after an initial COVID-19 infection. Symptoms can last weeks, months or years and are often debilitating. The World Health Organization defines long COVID as starting three months after infection, but other definitions put the start of long COVID at four weeks.

Rehabilitation after COVID-19 is needed in individuals experiencing longer-term disabling illness at any stage of COVID-19 infection. The rehabilitation of individuals with COVID-19 includes screening for the need for rehabilitation, participation of a multi-disciplinary team to evaluate and manage the individual's disabilities, use of four evidence based classes for rehabilitation, as well as individualised interventions for other problems.
There is increasing evidence suggesting that COVID-19 causes both acute and chronic neurologicalor psychological symptoms. Caregivers of COVID-19 patients also show a higher than average prevalence of mental health concerns. These symptoms result from multiple different factors.
Suicide cases have remained constant or decreased since the outbreak of the COVID-19 pandemic. According to a study done on twenty-one high and upper-middle-income countries in April–July 2020, the number of suicides has remained static. These results were attributed to a variety of factors, including the composition of mental health support, financial assistance, having families and communities work diligently to care for at-risk individuals, discovering new ways to connect through the use of technology, and having more time spent with family members which aided in the strengthening of their bonds. Despite this, there has been an increase in isolation, fear, stigma, abuse, and economic fallout as a result of COVID-19. Self-reported levels of depression, anxiety, and suicidal thoughts were elevated during the initial stay-at-home periods, according to empirical evidence from several countries, but this does not appear to have translated into an increase in suicides.
In the waning months of 2022, the first northern hemisphere autumn with the nearly full relaxation of public health precautions related to the COVID-19 pandemic, hospitals in the United States and Canada began to see overwhelming numbers of pediatric care patients, primarily driven by a massive upswing in respiratory syncytial virus (RSV) cases, but also flu, rhinovirus, enterovirus, and SARS-CoV-2.
