What causes COVID-19?
COVID-19 is caused by infection with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus strain..
What is the difference between people who have asymptomatic or pre-symptomatic COVID-19?
Both terms refer to people who do not have symptoms. The difference is that ‘asymptomatic’ refers to people who are infected but never develop any symptoms, while ‘pre-symptomatic’ refers to infected people who have not yet developed symptoms but go on to develop symptoms later.
Who is most at risk for COVID-19?
COVID-19 is often more severe in people 60+yrs or with health conditions like lung or heart disease, diabetes or conditions that affect their immune system.
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 are foods to avoid during the COVID-19 pandemic?
See full answerReduce foods such as red and fatty meats, butter and full-fat dairy products, palm oil, coconut oil, solid shortening and lard. Avoid trans fats as much as possible. Read nutrition labels to ensure that partially hydrogenated oils are not listed in the ingredients. If food labels are not available, avoid foods which commonly contain trans fats such as processed and fried foods, like doughnuts and baked goods – including biscuits, pie crusts, frozen pizzas, cookies, crackers and margarines that include partially hydrogenated fat.If in doubt, minimally processed foods and ingredients are better choices. Consume enough fibre Fibre contributes to a healthy digestive system and offers a prolonged feeling of fullness, which helps prevent overeating.
Should children wear a mask during the COVID-19 pandemic?
See full answerWHO advises that people always consult and abide by local authorities on recommended practices in their area. An international and multidisciplinary expert group brought together by WHO reviewed evidence on COVID-19 disease and transmission in children and the limited available evidence on the use of masks by children.Based on this and other factors such as childrens’ psychosocial needs and developmental milestones, WHO and UNICEF advise the following:Children aged 5 years and under should not be required to wear masks. This is based on the safety and overall interest of the child and the capacity to appropriately use a mask with minimal assistance.
Can water transmit COVID-19?
Although persistence in drinking-water is possible, there is no evidence from surrogate human coronaviruses that they are present in surface or groundwater sources or transmitted through contaminated drinking water.
Has COVID-19 been detected in drinking water supplies?
The COVID-19 virus has not been detected in drinking-water supplies, and based on current evidence, the risk to water supplies is low.
How long does the virus that causes COVID-19 last on surfaces?
Recent research evaluated the survival of the COVID-19 virus on different surfaces and reported that the virus can remain viable for up to 72 hours on plastic and stainless steel, up to four hours on copper, and up to 24 hours on cardboard.
How can the virus that causes COVID-19 spread through surfaces?
The virus can also spread after infected people sneeze, cough on, or touch surfaces, or objects, such as tables, doorknobs and handrails. Other people may become infected by touching these contaminated surfaces, then touching their eyes, noses or mouths without having cleaned their hands first.
Can the coronavirus disease spread through feces?
The risk of catching the COVID-19 virus from the faeces of an infected person appears to be low. There is some evidence that the COVID-19 virus may lead to intestinal infection and be present in faeces. Approximately 2−10% of cases of confirmed COVID-19 disease presented with diarrhoea (2−4), and two studies detected COVID-19 viral RNA fragments in the faecal matter of COVID-19 patients (5,6).However, to date only one study has cultured the COVID-19 virus from a single stool specimen (7). There have been no reports of faecal−oral transmission of the COVID-19 virus.
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.
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.
Are pools and water areas safe to use during the COVID-19 pandemic?
See full answerGym, beach, swimming pool, spa, sauna and steam bath facilities can be used safely with certain restrictions, as determined by national guidelines. In particular, look for the following measures:• a maximum number of people allowed to ensure adequate physical distancing• fabric mask policies required by local or national regulations• hand washing stations, especially in the toilet and change room areas• single use towels only • a bin for guests to place their towel after use for laundering• individual use drinking water• tissues and waste containers with lids• high touch areas such as door handles disinfected regularly throughout the day
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.
Should you meet with other people during the COVID-19 pandemic?
In this difficult period it is best to meet virtually but if you have to meet others, do it carefully and with the right precautions.
What surfaces should be cleaned during the COVID-19 pandemic?
High-touch surfaces in these non-health care settings should be identified for priority disinfection such as door and window handles, kitchen and food preparation areas, counter tops, bathroom surfaces, toilets and taps, touchscreen personal devices, personal computer keyboards, and work surfaces.
