The SARS-CoV-2 virus, which causes COVID-19, can lead to a range of symptoms, from mild to severe and life-threatening. While most people can treat COVID-19 symptoms at home, hospitals play a crucial role in managing severe cases. Treatments in hospitals aim to prevent severe disease and manage complications. This includes providing extra oxygen, ventilator support for breathing, IV fluids, and antiviral medications. Physicians also use therapies like steroids and monoclonal antibodies to reduce mortality and speed up recovery. Hospitals also play a role in vaccination, which is the first step in preventing severe COVID-19 outcomes.

Hospitals check oxygen levels and may provide extra oxygen or ventilator support
While most people can treat COVID-19 symptoms at home, hospital care may be required in some cases. If a patient is displaying basic COVID-19 symptoms, such as a mild fever or cough, they will usually be sent home. However, if the case is severe, medical staff will check for signs that the illness is causing more serious problems. This includes checking the levels of oxygen in the patient's blood with a clip-on finger monitor.
If oxygen levels are low, the patient may be given extra oxygen through small tubes placed just inside the nostrils. In very serious cases, doctors will connect the patient to a ventilator, a machine that breathes for them. Doctors will closely monitor the patient's breathing, with the goal of allowing the infection to run its course and for the lungs to heal enough to breathe independently again.
In addition to oxygen and ventilator support, doctors may administer an antiviral medicine to keep symptoms from worsening and help speed up recovery. Dexamethasone, a cheap and common steroid, has been shown to reduce mortality in severely ill patients. Tocilizumab, an anti-inflammatory drug, has also been used to treat COVID-19 patients. The antiviral drug remdesivir is widely used in hospitalized patients and has shown some promise in speeding up recovery.
Monoclonal antibodies are another treatment option that has received emergency use authorization from the FDA. These lab-made proteins mimic the body's immune response and block the virus from attaching to cells. However, they must be infused at a hospital or specialized site within days of the first symptoms, presenting logistical challenges. While treatments for COVID-19 are available, it is important to start treatment early, within 5-7 days of developing symptoms, to effectively reduce the risk of hospitalization and severe illness.

They may administer antiviral drugs to speed up recovery and reduce symptoms
Vaccines are the preferred strategy for preventing SARS-CoV-2, the virus that causes COVID-19. However, antiviral drugs are important in the prevention and control of viral diseases, particularly in the acute treatment of new outbreaks. They can significantly alleviate the disease, reduce mortality, and serve as an effective alternative or supplement to vaccines. Antiviral medications target specific parts of the virus to stop it from multiplying in the body once someone is infected, helping to prevent severe illness and death.
Research on antiviral drugs is one of the key strategies for coronavirus prevention and control. Based on key replication mechanisms, such as the viral life cycle, a series of antiviral drug studies have been performed by blocking one or a combination of viral life cycle stages, resulting in effective drugs. Antiviral drugs can be used to prevent the virus from entering host cells, as well as during the biosynthesis and assembly stages of the viral replication cycle.
While vaccines are the first step to preventing severe health outcomes from COVID-19, antiviral treatments can be used in conjunction with vaccines to help speed up recovery and reduce symptoms. Oral antiviral treatments such as Paxlovid and Lagevrio are available for certain people at a lower cost. These medications can be used to treat mild to moderate COVID-19 in people who are more likely to get very sick, and they must be started within 5-7 days of the onset of symptoms to be effective.
It is important to note that the benefits of COVID-19 treatment outweigh the risk of rebound if you are at high risk for severe illness. Additionally, some treatments may have side effects or interact with other medications, so it is important to consult with a healthcare provider before starting any treatment.

Monoclonal antibodies can be used to prevent severe illness
Monoclonal antibody therapy is different from a COVID-19 vaccine. While vaccines trigger the body's natural immune response, monoclonal antibodies provide the body with the antibodies it needs to protect itself from severe illness if you are at high risk. This therapy is particularly beneficial for people aged 65 and above and those with underlying health conditions that put them at higher risk of severe illness or hospitalisation.
There are currently two types of monoclonal antibody treatments authorised for pre-exposure prophylaxis: Evusheld and Pemgarda (Pemivibart). Evusheld is a combination of two long-acting monoclonal antibodies and is given as an injection. It is intended for people with specific health problems that put them at high risk of severe illness and who are unlikely to respond to COVID-19 vaccination. Pemgarda is authorised for use in people who are moderately or severely immunocompromised and have not been exposed to the virus.
It is important to note that monoclonal antibody treatments should not be used as a replacement for COVID-19 vaccinations or preventive measures such as good hygiene and social distancing. They are intended for high-risk individuals who are most likely to be hospitalised or face severe health outcomes due to COVID-19.

Dexamethasone and tocilizumab are steroidal anti-inflammatories that reduce mortality
COVID-19 is caused by the SARS-CoV-2 virus, which spreads through respiratory droplets. Its symptoms can range from mild and cold-like to severe and life-threatening. In severe cases, COVID-19 patients may require hospitalisation and intensive care unit (ICU) management due to mechanical ventilation or sepsis management.
Several treatments are available for COVID-19 patients, including antiviral and anti-inflammatory medications such as hydroxychloroquine, remdesivir, monoclonal antibodies, and convalescent serum. The standard of care (SOC) for severe COVID-19 includes antiviral therapy, such as remdesivir or lopinavir/ritonavir, along with supportive treatment. Steroids like methylprednisolone have also been included in the SOC.
Dexamethasone and tocilizumab have emerged as effective options for reducing mortality in severe COVID-19 patients. Tocilizumab has been shown to reduce the time of mechanical ventilation and shorten ICU and hospital stays. A meta-analysis found that the addition of tocilizumab to the SOC significantly reduced mortality, with a mortality rate of 22.4% compared to 26.21% in the SOC group.
Dexamethasone, a corticosteroid, has been found to reduce 28-day mortality in COVID-19 patients receiving respiratory support. It is a more affordable alternative to tocilizumab. However, larger studies are needed to confirm the benefit of steroids in COVID-19 treatment.

Vaccination is the first step to prevent severe outcomes and hospitalisation
Vaccination is the first line of defence against COVID-19, and it plays a crucial role in preventing severe outcomes and hospitalisation. COVID-19 is caused by the SARS-CoV-2 virus, which can lead to serious illness and even death in some cases. Vaccination is highly effective in protecting people from the worst effects of the virus and reducing the burden on healthcare systems.
COVID-19 vaccines are designed to trigger an immune response in the body, generating antibodies that recognise and fight off the SARS-CoV-2 virus. This immune response helps prevent severe illness by reducing the virus's ability to infect and damage the body's vital organs, especially the lungs. Vaccinated individuals are much less likely to experience severe symptoms that require hospitalisation, such as respiratory distress.
The vaccines have proven effective in reducing hospitalisations worldwide. Studies have shown that the risk of hospitalisation is significantly lower among vaccinated individuals, even during the Omicron wave. For example, a US study found that the vaccine was 68% effective in preventing hospitalisation among children aged 5 to 11 and 40% effective among adolescents aged 12 to 18. Similar trends were observed in a study from England, where the risk of hospitalisation was substantially lower among those who had received one, two, or more vaccine doses.
Vaccination is particularly important for individuals at higher risk of severe COVID-19, such as those with underlying medical conditions like heart disease or those who are immunocompromised. These individuals may require additional vaccine doses to ensure adequate protection. Pregnant individuals are also encouraged to get vaccinated as they are at increased risk of severe illness during pregnancy.
In addition to preventing hospitalisation, vaccination also reduces the risk of developing "long COVID," where symptoms persist for months or years. A review by the European Centre for Disease Prevention and Control (ECDC) found that vaccination reduced the likelihood of long COVID by approximately 27% in fully vaccinated adults.
