COVID can trigger a very itchy widespread rash called urticaria. This is sometimes called nettle-rash or hives and appears suddenly as smooth raised areas ('wheals') on the skin which can come and go quite quickly over hours. This can come up early in the COVID infection but can last for months afterwards.

Can you catch COVID-19 again?

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.

What is long COVID-19?

How long it takes to recover from coronavirus (COVID-19) is different for everybody. While most people recover quickly, some people have symptoms that last weeks or months after the infection has gone. This is sometimes called long COVID.

What are the organs most affected by COVID‐19?

The lungs are the organs most affected by COVID‐19

What are some of the most common symptoms of the COVID-19 Delta variant?

Cough, fatigue, headache and loss of taste and/or smell continue to be the most commonly reported symptoms in those testing positive.

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 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 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%).

Can the coronavirus survive on surfaces?

It is not certain how long the virus that causes COVID-19 survives on surfaces, but it seems likely to behave like other coronaviruses. A recent review of the survival of human coronaviruses on surfaces found large variability, ranging from 2 hours to 9 days (11).

The survival time depends on a number of factors, including the type of surface, temperature, relative humidity and specific strain of the virus.

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.

Can 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.

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.

What is herd immunity in terms of COVID-19?

Herd immunity', also known as 'population immunity', is the indirect protection from an infectious disease that happens when a population is immune either through vaccination or immunity developed through previous infection. WHO supports achieving 'herd immunity' through vaccination, not by allowing a disease to spread through any segment of the population, as this would result in unnecessary cases and deaths.

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.

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.

Does obesity increase the risk of getting the COVID-19?

The current evidence does not suggest that having excess weight increases people’s chances of contracting COVID-19. However, the data does show that obese people are significantly more likely to become seriously ill and be admitted to intensive care with COVID-19 compared to those with a healthy BMI.

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.

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.

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.

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.

What are some common side effects of the COVID-19 vaccine in children?

Common side effects their arm feeling heavy or sore where they had the injection feeling achy or like they have the flu feeling tired having a headache

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.

Can you get a fever or temperature after the COVID-19 vaccine?

Although a fever can occur within a day or two of vaccination, if you have any other COVID-19 symptoms or your fever lasts longer, stay at home and arrange to have a test.
