Published Jan 22, 2026
After having coronavirus (COVID-19), you may still have a loss of, or change in, sense of smell or taste. It can take time for your sense of smell or taste to recover. You may find that foods smell or taste differently after having coronavirus. Food may taste bland, salty, sweet or metallic.
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.
What are the organs most affected by COVID‐19?
The lungs are the organs most affected by COVID‐19
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 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.
35 related questions foundWhat 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.
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.
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.
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 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.
Can I become infected with COVID-19?
COVID-19, along with many other respiratory infections such as influenza (flu), can spread easily and cause serious illness in some people. You may be infected with a respiratory virus such as COVID-19 and not have any symptoms but still pass infection onto others.
Can you contract COVID-19 by touching contaminated surfaces?
People could catch COVID-19 by touching contaminated surfaces or objects – and then touching their eyes, nose or mouth. If they are standing within one meter of a person with COVID-19 they can catch it by breathing in droplets coughed out or exhaled by them. In other words, COVID-19 spreads in a similar way to flu.
Can you get the coronavirus disease (COVID-19) from packaging?
The risk of imported food and packaging from affected countries being contaminated with coronavirus is very unlikely. This is because the law requires the exporter to follow the right controls during the packing and shipping process to ensure good hygiene is met.
Is the coronavirus disease spread through food?
COVID-19 is a respiratory illness. It is not known to be transmitted by exposure to food or food packaging.
How long have coronaviruses existed?
The most recent common ancestor (MRCA) of all coronaviruses is estimated to have existed as recently as 8000 BCE, although some models place the common ancestor as far back as 55 million years or more, implying long term coevolution with bat and avian species.
Can COVID-19 spread through water while swimming?
Fact: Water or swimming does not transmit the COVID-19 virus
The COVID-19 virus does not transmit through water while swimming. However, the virus spreads between people when someone has close contact with an infected person.
WHAT YOU CAN DO:
Avoid crowds and maintain at least a 1-metre distance from others, even when you are swimming or at swimming areas. Wear a mask when you’re not in the water and you can’t stay distant. Clean your hands frequently, cover a cough or sneeze with a tissue or bent elbow, and stay home if you’re unwell.
What are the long lasting fruits and vegetables I should buy for COVID-19 quarantine?
WHO recommends consuming a minimum of 400 g (i.e. 5 portions) of fruits and vegetables per day. Citrus fruits like oranges, clementines and grapefruit are good options, as well as bananas and apples, which can also be cut into smaller pieces and frozen for later consumption or to add to smoothies.
Root vegetables such as carrots, turnips and beets, as well as vegetables like cabbage, broccoli and cauliflower are relatively nonperishable. Garlic, ginger and onions are also great options to keep at home, as they can be used to add flavour to a variety of meals.

Can you take the COVID-19 vaccine if you have allergies?
Most people with allergies (including food or penicillin allergies) can be vaccinated against COVID-19.
Tell healthcare staff before you're vaccinated if you've ever had a serious allergic reaction (including anaphylaxis). They may ask what you're allergic to, to make sure you can have the vaccine.
