Do COVID-19 and tuberculosis spread in the same way?
See full answerTB bacilli remain suspended in the air in droplet nuclei for several hours after a TB patient coughs, sneezes, shouts, or sings, and people who inhale them can get infected.
The size of these droplet nuclei is a key factor determining their infectiousness.
Their concentration decreases with ventilation and exposure to direct sunlight.COVID-19 transmission has primarily been attributed to the direct breathing of droplets expelled by someone with COVID-19 (people may be infectious before clinical features become apparent).
Droplets produced by coughing, sneezing, exhaling and speaking may land on objects and surfaces, and contacts can get infected with COVID-19 by touching them and then touching their eyes, nose or mouth .
Handwashing, in addition to respiratory precautions, are thus important in the control of COVID-19..
What is the percentage of people who need to be immune against COVID-19 in order to achieve herd immunity?
See full answerWe 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. Until we better understand COVID-19 immunity, it will not be possible to know how much of a population is immune and how long that immunity last for, let alone make future predictions. These challenges should preclude any plans that try to increase immunity within a population by allowing people to get infected.
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.
What is the most likely ecological reservoirs for coronavirus disease?
The most likely ecological reservoirs for SARS-CoV-2 are bats, but it is believed that the virus jumped the species barrier to humans from another intermediate animal host. This intermediate animal host could be a domestic food animal, a wild animal, or a domesticated wild animal which has not yet been identified.
What kind of mask is recommended to prevent COVID-19 transmission?
Fabric masks are recommended to prevent onward transmission in the general population in public areas, particularly where distancing is not possible, and in areas of community transmission. This could include the school grounds in some situations. Masks may help to protect others, because wearers may be infected before symptoms of illness appear. The policy on wearing a mask or face covering should be in line with national or local guidelines. Where used, masks should be worn, cared for and disposed of properly.
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.
Can the coronavirus disease be transmitted in hot or humid climates?
From the evidence so far, the COVID-19 virus can be transmitted in ALL AREAS, including areas with hot and humid weather. Regardless of climate, adopt protective measures if you live in, or travel to an area reporting COVID-19. The best way to protect yourself against COVID-19 is by frequently cleaning your hands. By doing this you eliminate viruses that may be on your hands and avoid infection that could occur by then touching your eyes, mouth, and nose.
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.
How does COVID-19 spread between people?
See full answerCOVID-19 is caused by the SARS-CoV-2 virus, which spreads between people, mainly when an infected person is in close contact with another person.The virus can spread from an infected person’s mouth or nose in small liquid particles when they cough, sneeze, speak, sing or breathe heavily. These liquid particles are different sizes, ranging from larger ‘respiratory droplets’ to smaller ‘aerosols’.Other people can catch COVID-19 when the virus gets into their mouth, nose or eyes, which is more likely to happen when people are in direct or close contact (less than 1 metre apart) with an infected person.
Does heat prevent COVID-19?
FACT: Exposing yourself to the sun or temperatures higher than 25°C DOES NOT protect you from COVID-19. You can catch COVID-19, no matter how sunny or hot the weather is. Countries with hot weather have reported cases of COVID-19.
What is the COVID-19 incubation period for children?
The incubation period for children is the same as in adults. The time between exposure to COVID-19 and when symptoms start is commonly around 5 to 6 days, and ranges from 1 to 14 days.
How to handle food safely during COVID-19 quarantine?
1. keep your hands, kitchen and utensils clean2. separate raw and cooked food, especially raw meat and fresh produce3. cook your food thoroughly4. keep your food at safe temperatures, either below 5 °C or above 60 °C; and5. use safe water and raw material.
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.
Can COVID-19 be transmitted between humans and animals?
Available evidence suggests that the virus is predominantly transmitted between people through respiratory droplets and close contact, but there are also examples of transmission between humans and animals. Several animals that have been in contact with infected humans, such as minks, dogs, domestic cats, lions and tigers, have tested positive for SARS-CoV-2.
Can COVID-19 spread through water while swimming?
Fact: Water or swimming does not transmit the COVID-19 virusThe 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.
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 COVID-19 be transmitted by fomite?
See full answerDespite consistent evidence as to SARS-CoV-2 contamination of surfaces and the survival of the virus on certain surfaces, there are no specific reports which have directly demonstrated fomite transmission. People who come into contact with potentially infectious surfaces often also have close contact with the infectious person, making the distinction between respiratory droplet and fomite transmission difficult to discern. However, fomite transmission is considered a likely mode of transmission for SARS-CoV-2, given consistent findings about environmental contamination in the vicinity of infected cases and the fact that other coronaviruses and respiratory viruses can transmit this way.
How to stay active during the COVID-19 quarantine?
See full answerFollow an online exercise class. Take advantage of the wealth of online exercise classes. Many of these are free and can be found on YouTube. If you have no experience performing these exercises, be cautious and aware of your own limitations.Walk. Even in small spaces, walking around or walking on the spot, can help you remain active. If you have a call, stand or walk around your home while you speak, instead of sitting down. If you decide to go outside to walk or exercise, be sure to maintain at least a 1-meter distance from other people.Stand up. Reduce your sedentary time by standing up whenever possible. Ideally, aim to interrupt sitting and reclining time every 30 minutes. Consider setting up a standing desk by using a high table or stacking a pile of books or other materials, to continue working while standing. During sedentary leisure time prior
