Do Vaccines Work After Infection?

Can COVID-19 be transmitted through food?

There is currently no evidence that people can catch COVID-19 from food.

The virus that causes COVID-19 can be killed at temperatures similar to that of other known viruses and bacteria found in food..

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.

Can the coronavirus spread via feces?

There is some evidence that COVID-19 infection may lead to intestinal infection and be present in faeces. However, to date only one study has cultured the COVID-19 virus from a single stool specimen. There have been no reports of faecal−oral transmission of the COVID-19 virus to date.

What is the incubation period of the coronavirus disease?

The incubation period of COVID-19, which is the time between exposure to the virus and symptom onset, is on average 5-6 days, but can be as long as 14 days. Thus, quarantine should be in place for 14 days from the last exposure to a confirmed case.

Are you immune to COVID-19 if you get it once?

Research is still ongoing into how strong that protection is and how long it lasts. WHO is also looking into whether the strength and length of immune response depends on the type of infection a person has: without symptoms (‘asymptomatic’), mild or severe. Even people without symptoms seem to develop an immune response.

Do vaccines against pneumonia protect against the coronavirus disease?

No. Vaccines against pneumonia, such as pneumococcal vaccine and Haemophilus influenza type B (Hib) vaccine, do not provide protection against the new coronavirus.The virus is so new and different that it needs its own vaccine. Researchers are trying to develop a vaccine against 2019-nCoV, and WHO is supporting their efforts.Although these vaccines are not effective against 2019-nCoV, vaccination against respiratory illnesses is highly recommended to protect your health.

Can we reach herd immunity against COVID-19 through natural infections?

See full answerAttempts to reach ‘herd immunity’ through exposing people to a virus are scientifically problematic and unethical. Letting COVID-19 spread through populations, of any age or health status will lead to unnecessary infections, suffering and death.The vast majority of people in most countries remain susceptible to this virus. Seroprevalence surveys suggest that in most countries, less than 10% of the population have been infected with COVID-19.We are still learning about immunity to COVID-19. Most people who are infected with COVID-19 develop an immune response within the first few weeks, but we don’t know how strong or lasting that immune response is, or how it differs for different people. There have also been reports of people infected with COVID-19 for a second time.

What are some side effects of Pfizer’s Covid vaccine?

Typical side effects may include swelling or pain at the point of injection, tiredness, fever or headache, as well as muscular or joint pain. The incidence of fever has so far been found to be higher after the second dose of the Pfizer-BioNTech vaccine.

Can COVID-19 be transmitted through feces or urine?

SARS-CoV-2 RNA has also been detected in other biological samples, including the urine and feces of some patients. One study found viable SARS-CoV-2 in the urine of one patient. Three studies have cultured SARS-CoV-2 from stool specimens. To date, however, there have been no published reports of transmission of SARS-CoV-2 through feces or urine.

Is a smoker at a higher risk of getting the COVID-19 virus than that a non-smoker?

See full answerAt the time of preparing this Q&A, there are no peer-reviewed studies that have evaluated the risk of SARS-CoV-2 infection associated with smoking. However, tobacco smokers (cigarettes, waterpipes, bidis, cigars, heated tobacco products) may be more vulnerable to contracting COVID-19, as the act of smoking involves contact of fingers (and possibly contaminated cigarettes) with the lips, which increases the possibility of transmission of viruses from hand to mouth. Smoking waterpipes, also known as shisha or hookah, often involves the sharing of mouth pieces and hoses, which could facilitate the transmission of the COVID-19 virus in communal and social settings.

What food should you avoid during COVID-19?

• When cooking and preparing food, limit the amount of salt and high-sodium condiments (e.g. soy sauce and fish sauce). • Limit your daily salt intake to less than 5 g (approximately 1 teaspoon), and use iodized salt. • Avoid foods (e.g. snacks) that are high in salt and sugar. • Limit your intake of soft drinks or sodas and other drinks that are high in sugar (e.g. fruit juices, fruit juice concentrates and syrups, flavoured milks and yogurt drinks).• Choose fresh fruits instead of sweet snacks such as cookies, cakes and chocolate.

How to eat healthy in quarantine during the COVID-19 pandemic?

See full answerConsume enough fibre because it contributes to a healthy digestive system and offers a prolonged feeling of fullness, which helps prevent overeating. To ensure an adequate fibre intake, aim to include vegetables, fruit, pulses and wholegrain foods in all meals. Whole grain foods include oats, brown pasta and rice, quinoa and whole-wheat bread and wraps, rather than refined grain foods such as white pasta and rice, and white bread.Good hydration is crucial for optimal health. Whenever available and safe for consumption, tap water is the healthiest and cheapest drink. It is also the most sustainable, as it produces no waste, compared to bottled water.
