For a while we've been noticing an increasing number of people reporting that their tongue doesn't look normal, particularly that it is white and patchy. Professor Tim Spector, COVID Symptom Study lead, tweeted about this in January and got a lot of responses - and some pictures!
What are signs and symptoms of the coronavirus disease?
Signs and symptoms include respiratory symptoms and include fever, cough and shortness of breath. In more severe cases, infection can cause pneumonia, severe acute respiratory syndrome and sometimes death.
Standard recommendations to prevent the spread of COVID-19 include frequent cleaning of hands using alcohol-based hand rub or soap and water; covering the nose and mouth with a flexed elbow or disposable tissue when coughing and sneezing; and avoiding close contact with anyone that has a fever and cough.
What are some of the symptoms of the omicron variant of COVID-19?
According to US CDC analysis, the five most common symptoms of the Omicron variant are cough, fatigue, congestion, runny nose and generalised body ache. Recently, the UK-based Zoe Covid app study added new symptoms such as nausea and loss of appetite.
What are the organs most affected by COVID‐19?
The lungs are the organs most affected by COVID‐19
Can you get COVID-19 more than once?
Yes, it is possible to get Covid-19 two, three or even more times. As new variants have emerged, and immunity from previous infection and immunisation has reduced over time, reinfection with Covid-19 has become increasingly common.
41 related questions foundCan you still catch COVID-19 after having the booster vaccine?
Can you still catch COVID-19 after having the vaccine? The COVID-19 vaccination will reduce the chance of you suffering from COVID-19. It may take a few days for your body to build up some protection from the booster.
Can you still get Covid after vaccine?
Like all medicines, no vaccine is completely effective, so you should continue to take recommended precautions to avoid infection. Some people may still get COVID-19 despite having a vaccination, but this should be less severe.
What are the complications of COVID-19?
Complications may include pneumonia, acute respiratory distress syndrome (ARDS), multi-organ failure, septic shock, and death.
Who are at higher risk of developing serious illness from COVID-19?
Older people, and those with underlying medical problems like cardiovascular disease, diabetes, chronic respiratory disease, and cancer are more likely to develop serious illness.
In what conditions does COVID-19 survive the longest?
Coronaviruses die very quickly when exposed to the UV light in sunlight. Like other enveloped viruses, SARS-CoV-2 survives longest when the temperature is at room temperature or lower, and when the relative humidity is low (<50%).
What are the common side effects of the Astra Zeneca COVID-19 vaccine?
The most frequently reported adverse reactions are injection site tenderness (68%), injection site pain (58%), headache (53%), fatigue (53%), myalgia (44%), malaise (44%), pyrexia (includes feverishness (33%) and fever ≥38°C (8%)), chills (32%), arthralgia (27%) and nausea (22%).
The majority of these adverse reactions were mild to moderate in severity and usually resolved within a few days of vaccination. Very rare cases of thrombosis with thrombocytopenia syndrome have been reported post-marketing within the first three weeks following vaccination (see section 4.4).
What are the possible side effects of the BNT162b2 COVID-19 vaccine?
The most common side effects with BNT162b2 (which may affect more than 1 in 10 people) were pain at the injection site, tiredness, headache, muscle pain, chills, joint pain and fever.
What are the most common adverse reactions to the covid-19 vaccine?
The most frequent adverse reactions in trials were pain at the injection site, fatigue, headache, myalgia (muscle pains), chills, arthralgia (joint pains), and fever; these were each reported in more than 1 in 10 people.
What should I do if I have symptoms of COVID-19?
If you have symptoms of a respiratory infection, such as COVID-19, and you have a high temperature or do not feel well enough to go to work or carry out normal activities, you are advised to try to stay at home and avoid contact with other people.
Can people with mild COVID-19 symptoms recover at home?
People with mild symptoms who are otherwise healthy should manage their symptoms at home. On average it takes 5–6 days from when someone is infected with the virus for symptoms to show, however it can take up to 14 days.
Can the coronavirus disease spread through food?
It is very unlikely that COVID-19 is transmitted through food. However, as a matter of good hygiene practice, anyone handling food should wash their hands often with soap and water for at least 20 seconds before doing so. Crockery and eating utensils should not be shared. Clean frequently touched surfaces regularly.
Do smokers get more severe symptoms of COVID-19 if infected?
Smoking any kind of tobacco reduces lung capacity and increases the risk of many respiratory infections and can increase the severity of respiratory diseases. COVID-19 is an infectious disease that primarily attacks the lungs. Smoking impairs lung function making it harder for the body to fight off coronaviruses and other respiratory diseases. Available research suggests that smokers are at higher risk of developing severe COVID-19 outcomes and death.
Are the elderly more vulnerable to the coronavirus disease?
The COVID-19 pandemic is impacting the global population in drastic ways. In many countries, older people are facing the most threats and challenges at this time.
Although all age groups are at risk of contracting COVID-19, older people face significant risk of developing severe illness if they contract the disease due to physiological changes that come with ageing and potential underlying health conditions.
Are people of a particular age vulnerable to coronavirus disease?
People of all ages can be infected by the COVID-19 virus.
Older people and younger people can be infected by the COVID-19 virus. Older people, and people with pre-existing medical conditions such as asthma, diabetes, and heart disease appear to be more vulnerable to becoming severely ill with the virus.
Can COVID-19 lead to mental and neurological complications?
Meanwhile, COVID-19 itself can lead to neurological and mental complications, such as delirium, agitation, and stroke. People with pre-existing mental, neurological or substance use disorders are also more vulnerable to SARS-CoV-2 infection ̶ they may stand a higher risk of severe outcomes and even death.
How long can you not eat or drink before a COVID-19 test?
Do not eat or drink for at least 30 minutes before doing your test to reduce the risk of spoiling the test.
Can I develop immunity to COVID-19 after testing positive for PCR?
If you have previously tested positive for COVID-19, you will probably have developed some immunity to the disease. However, it cannot be guaranteed that everyone will develop immunity, or how long it will last. It is possible for PCR tests to remain positive for some time after COVID-19 infection.
How long after having COVID-19 can I get the spring booster vaccine?
If you are unwell, wait until you have recovered to have your vaccine. If you have had confirmed COVID-19 you should ideally wait 4 weeks before having your spring booster.
How do we achieve herd immunity against COVID-19?
To safely achieve herd immunity against COVID-19, a substantial proportion of a population would need to be vaccinated, lowering the overall amount of virus able to spread in the whole population.
Does BCG vaccine protect you from getting the coronavirus disease?
There is no evidence that the Bacille Calmette-Guérin vaccine (BCG) protects people against infection with COVID-19 virus. Two clinical trials addressing this question are underway, and WHO will evaluate the evidence when it is available. In the absence of evidence, WHO does not recommend BCG vaccination for the prevention of COVID-19. WHO continues to recommend neonatal BCG vaccination in countries or settings with a high incidence of tuberculosis.
