What Other Drugs Have Been Trialled
Remdesivir is an antiviral drug – originally developed to treat Ebola – that showed promising early results.
However, in October 2020, the World Health Organization advised that it “appeared to have little or no effect on hospitalised Covid,” in terms of death rates, length of stay in hospital, or seriousness of illness.
Another drug being assessed by the Principle trial is Ivermectin, which is commonly used to treat a wide range of parasitic diseases such river blindness.
It has controversially been promoted for use across Latin America and in South Africa, despite little hard evidence so far that it works.
Prolonged Recovery And Other Complications
While most symptoms will disappear on their own, some people have reported specific symptoms lingering. These include fever, loss of taste or smell, fatigue and a prolonged cough.
COVID-19 can damage the heart and kidneys. Bacterial infection is one possible complication. These complications may occur as late as three weeks after onset of the initial illness. Researchers are still trying to identify why some people experience symptoms for longer than other.
Initial research about prolonged loss of smell says that patients typically lose their sense of smell because of cleft syndrome. This is when the tissue around the part of your nose responsible for smell swells up. Typically, when the virus passes and swelling goes down, your sense of smell come back. But this hasnt been the case for all. For those with severe COVID-19 cases, some have reported losing their sense of smell for months. Some may run the risk of losing it permanently due to the body attacking the nasal passage when fighting COVID-19.
Researchers will continue to study these cases. Scientists hope to have more concrete findings in the future.
We still have a lot to learn when it comes to COVID-19. Symptoms vary based on age and underlying health conditions, but those listed above are the most common.
If you are experiencing any of the above symptoms, call your doctor for advice. And make sure to isolate if you are sick.

Mild Vs Moderate Vs Severe Symptoms
COVID-19 severity is often divided into categories like mild, moderate, and severe. But what do these terms actually mean?
According to the COVID-19 treatment guidelines published by the National Institutes of Health , theyre defined as:
Research has found that about 81 percent of people with COVID-19 have a mild or moderate illness. According to the Centers for Disease Control and Prevention , most people with mild to moderate COVID-19 can recover at home.
Even if you have mild or moderate COVID-19, its still important to continue to monitor your symptoms as you recover. Even if you only have mild symptoms, its possible that they may begin to worsen, leading to more serious illness.
One potential symptom of COVID-19 is loss of smell or taste. An of 24 studies estimated a prevalence of 41 percent and 38.2 percent for loss of smell and taste, respectively.
Loss of smell and taste is also associated with mild COVID-19. A evaluated this symptom in 1,363 people with COVID-19.
Researchers observed loss of smell and taste in 85.9 percent of people with mild illness compared to 4.5 to 6.9 percent of people with moderate to severe illness. This symptom disappeared in 95 percent of individuals within 6 months.
I felt a little congested, but nothing more than allergies could cause. Then I realized one afternoon I could no longer smell my coffee, so I got tested. The rapid test came back positive.

What We Dont Know Yet About Covid
Beyond understanding the immune system and our health-care systems, there are many aspects of the virus that are currently unknown to medical professionals, said Jandu.
There could be something about the way its causing infection, something that we just dont know yet. Or it could be the fact that its something new and its spreading so quickly among the population, she said.
New research from a Chinese group of scientists has suggested there could be two strains of the virus, with one causing more severe outcomes. But new reports like this one havent had the opportunity to be reviewed extensively by the academic community, said Jandu.
We cant draw conclusions from this work yet. There are a lot of reports coming out, and everything is just fresh off the press, she said. There needs to be more time to peer review and critique the data before they can be taken with certainty, she explained.
However, at the same time reports need to be released quickly so information can be shared about the virus, she said. More will be known as it continues to be studied.
This is something that is perplexing the scientific and biomedical community because it is such a new virus. Were learning more and more about it every dayand were trying our best in real-time to understand how its causing infection and how is its causing pathology, she said.

How Often Do People Die Of It
The case fatality rate refers to the number of deaths among those who have tested positive for coronavirus. Globally, the case fatality rate today stands at 4%.
But this rate varies country to country and even within countries. These variations may partially be explained by whether hospitals has been overwhelmed or not.
The case fatality rate in Wuhan was 5.8% . In the rest of China, it was at 0.7%.
Similarly in Europe, Italys case fatality rate is , greatly surpassing that of Germany .
However the case fatality rate only includes people who are tested and confirmed as having the virus.
Some modelling estimates suggest that if you calculated the number of deaths from the total number of cases the proportion of people who die from coronavirus might be more like 1%.

How Could Contact Tracing Help Slow The Spread Of Covid
Anyone who comes into close contact with someone who has COVID-19 is at increased risk of becoming infected themselves, and of potentially infecting others. Contact tracing can help prevent further transmission of the virus by quickly identifying and informing people who may be infected and contagious, so they can take steps to not infect others.
Contact tracing begins with identifying everyone that a person recently diagnosed with COVID-19 has been in contact with since they became contagious. In the case of COVID-19, a person may be contagious 48 to 72 hours before they started to experience symptoms.
The contacts are notified about their exposure. They may be told what symptoms to look out for, advised to isolate themselves for a period of time, and to seek medical attention as needed if they start to experience symptoms.
Which Vaccines Has The Fda Approved And Authorized For Covid
In August 2021, the FDA granted full approval to the mRNA COVID-19 vaccine developed by Pfizer and BioNTech. This vaccine had received emergency use authorization in December 2020. The mRNA COVID-19 vaccine developed by Moderna also received EUA in December 2020. The Johnson & Johnson adenovirus vaccine was granted EUA by the FDA in late February 2021. Use of the Johnson & Johnson vaccine resumed on April 23, 2021, after a temporary pause.

How Long Is The Incubation Period Of Novel Coronavirus
If you contract the virus, symptoms may appear anywhere between two and 14 days after you contracted it.
If someone is under observation , they are monitored for 14 days for possible onset of symptoms, says Eudene Harry, MD, an emergency medicine physician in Orlando, Florida. If you haven’t developed symptoms at that point, youre likely in the clear.
Employers Can Accelerate Covid
During the first four months of the COVID-19 vaccination campaign in the United States, demand for the vaccine was far greater than supply. Increasingly, the opposite is happening: The vaccine doses available exceed the number of people stepping forward to receive them.1 Some states and counties have even turned away unneeded shipments of vaccines.2

Mild Symptoms Of Covid
Because this particular coronavirus is so new it first appeared in late 2019 in Wuhan, China were still learning about it and the symptoms it causes. However, when mild symptoms occur, they can mimic the common cold and include:
- Low-grade fever
- Nasal congestion
- Mild, dry cough
- Mild body aches
There have also been reports of people testing positive for the virus without having any symptoms.
A joint World Health Organization-China mission of 25 infectious disease experts went to China in February. According to their report, 80 percent of known COVID-19 cases cause mild to moderate symptoms that dont require special treatment. So, if you have these mild symptoms, you can get better at home without a trip to your doctors office. Your immune system will do its job and fight the virus.
Can People Without Symptoms Spread The Virus To Others
“Without symptoms” can refer to two groups of people: those who eventually do have symptoms and those who never go on to have symptoms . During this pandemic, we have seen that people without symptoms can spread the coronavirus infection to others.
A person with COVID-19 may be contagious 48 hours before starting to experience symptoms. In fact, people without symptoms may be more likely to spread the illness, because they are unlikely to be isolating and may not adopt behaviors designed to prevent spread.
But what about people who never go on to develop symptoms? A study published in JAMA Network Open found that almost one out of every four infections may be transmitted by individuals with asymptomatic infections.
Getting vaccinated once you are eligible is important for protecting not just yourself but others as well early evidence suggests that you’re less likely to infect others once you’ve been vaccinated.

What To Do If Symptoms Appear
If a person believes they have symptoms of COVID-19, or they may have been exposed to the virus that causes it, they should self-isolate in their home and call a doctor. Do not visit a healthcare facility without calling ahead first.
According to the
- washing the hands frequently with soap and water for at least 20 seconds
- using hand sanitizer containing at least 60% alcohol, if soap and water are not available
- avoiding touching the face, particularly the nose, eyes, or mouth with unwashed hands
- staying at least 6 feet, or 2 meters, away from people who are outside of a persons household
- wearing a mask in public places, when around people from other households, or in situations where physical distancing is difficult
- covering coughs and sneezes with a tissue or the inside of the elbow, and disposing of used tissues immediately in the trash
- cleaning and disinfecting frequently touched objects and surfaces every day
People can transmit SARS-CoV-2 even if they do not feel sick, so it is essential to follow these guidelines at all times, wherever possible.
The CDC recommends that people wear cloth face masks any time they are in a public setting. This will help slow the spread of the virus from people who do not know that they have contracted it, including those who are asymptomatic. People should wear cloth face masks while continuing to practice physical distancing. Note: It is critical that surgical masks and N95 respirators are reserved for healthcare workers.
If You Have Brown Or Black Skin
Pulse oximeters work by shining light through your skin to measure the level of oxygen in your blood.
There have been some reports they may be less accurate if you have brown or black skin. They may show readings higher than the level of oxygen in your blood.
You should still use your pulse oximeter if you’ve been given one. The important thing is to check your blood oxygen level regularly to see if your readings are going down.

People At Higher Risk Of Severe Illness
People with underlying health conditions are most at risk of COVID-19 becoming a severe illness. You are more vulnerable if you:
- are over 70 years old with a medical condition
- live in an aged care facility where spread can occur more easily
- have a medical condition and/or compromised immunity.
- are pregnant.
Other risk factors include ethnicity, smoking and obesity.
If you have an underlying health condition and at high risk of getting very sick from COVID-19 you may get early access to the COVID-19 vaccine. This is along with those who are over 65, work at the border or in frontline health care roles. Read about getting the vaccine.

Just How Fast Does Covid
By the time I count to 10, 22 more people around the globe have contracted COVID-19. I glance up a minute or so later, and the number has ballooned to over 300. And while I know COVID-19 is a global pandemic thats taken nearly a million lives and counting, its exactly that and counting thats giving me pause right now. COVID-19 is relentless.
Im on a site thats called COVID-19 Spreading Rates, developed by data experience designer Jan Willem Tulp. Like countlesspandemic visualizations before, its an interactive site that conveys the spread of COVID-19 worldwide. But instead of using world maps or line graphs, it features a series of radial progress bars, which count new COVID-19 cases as they come in.
That means each country looks something like the Apple Watch activity tracker, but instead of steps, they depict new cases of COVID-19.
I hope people become more aware of how fast the virus is spreading, especially in some countries, says Tulp. So by making it a bit more tangible, I hope people get a sense of urgency and responsibility.
In Burundi, where a new COVID-19 case is found every 17 hours, that dial fills slowlytoo slowly to see. But in the U.S., where a person is diagnosed with COVID-19 every 2.5 seconds, the graph is in a constant red spin. Since I loaded the page as I began writing this article, 339 Americans have tested positive for the virus.

Taking Care Of Children
What is COVID-toe or COVID-fingers, and how can this affect my child?
People can react to infections in different ways. It is not uncommon for someone to have a viral infection and have a rash on his or her body. Like most viral rashes, COVID toe/fingers are another way the body can respond to a viral infection. It is possible this is a skin reaction or a small clog, or micro clot, in the blood vessels. It can be painful for some.
Should you note a rash or COVID fingers/toes in addition to , it is important to call your healthcare provider. Not all people with COVID-19 get COVID-toe, and not all people with swollen toes or fingers have COVID-19.
What are the chances my child will catch multisystem inflammatory syndrome at daycare or at the playground?
We are still learning about multisystem inflammatory syndrome and how it affects children. It is a rare condition, so the chances are low in general. However, we do not know why some children have gotten sick with multisystem inflammatory syndrome and others have not. Based on what we know, the best way to protect your child is by taking everyday actions to in your child and the entire household.

What Are The Stages And Symptoms Of Covid
- Day 1: The symptoms usually start with a fever, a dry cough and mild breathing issues which may get worse over the next week. You also may have symptoms of a sore throat, coughing up mucus, diarrhea, nausea, body aches and joint pain.
- Day 7: Breathing may become difficult or laboured. This is called dyspnoea.
- Day 9: Sepsis may start, this is the body’s extreme response to an infection that can lead to organ failure or injury.
- Day 10-12: People who have mild COVID-19 start to have an improvement in their fever and cough, but in serious cases their fever and cough continues.
- Acute respiratory distress syndrome starts to be diagnosed, this is a respiratory problem when there is widespread inflammation in the lungs.
- Day 12: This is the median day to be admitted into the intensive care unit .
- Day 15: Acute kidney and cardiac injury becomes evident.
- Day 18.5: The median time it takes from the first symptoms of COVID-19 to death is 18.5 days.
- Day 22: This is the median amount of days it takes for COVID-19 survivors to be released from hospital
A study published in The Lancet studied the patients who were hospitalized with COVID-19 and compared details of the patients who passed away and patients that survived.
This figure below shows the progression and duration of the major symptoms of COVID-19 in survivors and non-survivors for hospitalized patients in the study.
