After that, wear a mask for 5 days. If you can't quarantine, wear a mask for 10 days. Try to stay away from people in your household. If you have symptoms, self-isolate. If you've received the recommended vaccine doses but not a booster, stay home for 5 days.
Get tested after at least 5 days. And wear a mask for 5 more days. If you're not able to stay home, wear a mask for 10 days. As you or your loved one recover, seek emotional support. Stay connected to others through texts, phone calls or videoconferences. Share your concerns. Rest and focus on enjoyable activities, such as reading, watching movies or playing online games.
You might worry about your health and the health of the sick person. This can affect your ability to eat, sleep and concentrate, as well as worsen chronic health problems. It may also increase your use of alcohol, tobacco or other drugs. If you have a mental health condition, such as anxiety or depression, continue with your treatment. Contact your doctor or mental health professional if your condition worsens. Caring for yourself can help you cope with stress. It will also help you be able to support your loved one's recovery.

It might become endemic in due course but pinning that down to is a bit difficult at this stage. Smallwood noted that widespread vaccination coverage would be key to moving to such a scenario but, for now, the conditions for endemicity were not being met.
Marco Cavaleri, head of biological health threats and vaccines strategy at the European Medicines Agency, the EU's drug regulator, said Tuesday that "nobody knows when exactly we'll be at the end of the tunnel" in terms of the pandemic becoming endemic, but added that progress is being made. Covid vaccination remains patchy around the world. While rich countries roll out booster shots and even discuss the possibility of fourth Covid jabs, poorer countries are still introducing their initial doses and many people remain unprotected by vaccines that have been proven to reduce the risk of severe infection, hospitalization and death.
According to Our World in Data , Booster shots are not unproblematic, however, with scientists at the WHO and elsewhere warning that continual boosters are not a viable strategy.
The EMA's Cavaleri said Tuesday that "repeated vaccinations within short intervals will not represent a sustainable long-term strategy. Biden deploys military medical teams to hospitals in six states as omicron disrupts essential services.

The drug may be used to treat adults and children ages 12 and older and weighing at least 88 pounds, who have been hospitalized for COVID Clinical trials suggest that in these patients, remdesivir may modestly speed up recovery time. In November , the Food and Drug Administration FDA issued an Emergency Use Authorization EUA for the use of baricitinib in combination with remdesivir in hospitalized adults and children two years and older who require respiratory support.
However, there is not yet enough evidence to support the use of this therapy instead of dexamethasone with or without remdesivir. Almost all people admitted to the hospital with COVID receive medications to help prevent blood clots. Doctors usually prescribe low dose heparin or enoxaparin. However, some patients require full doses of anticoagulants if they already have developed blood clots or have a high risk of doing so. Doctors always need to balance the risk of dangerous bleeding when prescribing full doses.
Monoclonal antibodies are manmade versions of the antibodies that our bodies naturally make to fight invaders, such as the SARS-CoV-2 virus. The treatments may be used to treat non-hospitalized adults and children over age 12 with mild to moderate symptoms who have recently tested positive for COVID, and who are at risk for developing severe COVID or being hospitalized for it.
All three of the FDA-authorized therapies attack the coronavirus's spike protein, making it more difficult for the virus to attach to and enter human cells. This has translated into a disadvantage when it comes to fighting the Omicron variant, which has more than 30 mutations on its spike protein. Laboratory studies have found that only one of the FDA-authorized monoclonal antibody treatments — sotrovimab — is effective against Omicron.
As of January , the number of patients who would benefit from monoclonal antibody treatment far exceeds the supply and the infrastructure to deliver this therapy. Once oral antiviral medications are more available, there will be more treatment options for high-risk patients. Monoclonal antibody treatment may also help to save lives in a specific subgroup of hospitalized COVID patients.
For these very ill hospitalized patients, the FDA has granted EUA for tocilizumab Actemra , a monoclonal antibody that blocks the action of IL-6, and thereby dampens the exaggerated immune system response. When people recover from COVID, their blood contains antibodies that their bodies produced to fight the coronavirus and help them get well.
Antibodies are found in plasma, a component of blood. Convalescent plasma — literally plasma from recovered patients — has been used for more than years to treat a variety of illnesses from measles to polio, chickenpox, and SARS. It is widely believed to be safe. A small but well-designed trial randomized, double-blind, and placebo-controlled was published in the New England Journal of Medicine in January The study only enrolled patients 65 years and older, and researchers screened the convalescent plasma to ensure it contained high levels of antibodies.
However, a meta-analysis of four peer-reviewed and published randomized clinical trials, published in JAMA , had less-promising results. The trials included in the analysis included patients with COVID who received either convalescent plasma, a placebo, or standard treatment. Compared to placebo and standard treatment, convalescent plasma did not significantly improve risk of death, length of hospital stay, or the need for a ventilator. The study authors noted that the studies used for this analysis were small, and future clinical trials might suggest more benefit from the therapy.
In order to donate plasma, a person must meet several criteria. A donor and patient must also have compatible blood types. Once plasma is donated, it is screened for other infectious diseases, such as HIV.
Each donor produces enough plasma to treat one to three patients. Donating plasma should not weaken the donor's immune system nor make the donor more susceptible to getting reinfected with the virus. An antiviral drug must be able to target the specific part of a virus's life cycle that is necessary for it to reproduce.
In addition, an antiviral drug must be able to kill a virus without killing the human cell it occupies. And viruses are highly adaptive.
Because they reproduce so rapidly, they have plenty of opportunity to mutate change their genetic information with each new generation, potentially developing resistance to whatever drugs or vaccines we develop.
The money will be used to speed up the development and testing of antiviral drugs that are already in clinical trials, and for additional drug discovery with a focus on medications that can be taken by mouth.
While COVID vaccines remain central to protection, antiviral medications may be important for people whose bodies do not mount a strong response to the vaccine, who experience breakthrough infections, and for those who are unvaccinated. These are only observations and not based on scientific studies. The WHO initially recommended using acetaminophen instead of ibuprofen to help reduce fever and aches and pains related to this coronavirus infection, but now states that either acetaminophen or ibuprofen can be used.
Rapid changes in recommendations create uncertainty. Since some doctors remain concerned about NSAIDs, it still seems prudent to choose acetaminophen first, with a total dose not exceeding 3, milligrams per day.
