Can COVID-19 cause severe disease
While COVID-19 is spreading rapidly, most people will experience only mild or moderate symptoms.
That said, this coronavirus can cause severe disease in some people..
What should I do if I feel unwell during the COVID-19 pandemic
See full answer• Know the full range of symptoms of COVID-19. The most common symptoms of COVID-19 are fever, dry cough, and tiredness. Other symptoms that are less common and may affect some patients include loss of taste or smell, aches and pains, headache, sore throat, nasal congestion, red eyes, diarrhoea, or a skin rash.• Stay home and self-isolate even if you have minor symptoms such as cough, headache, mild fever, until you recover. Call your health care provider or hotline for advice. Have someone bring you supplies. If you need to leave your house or have someone near you, wear a medical mask to avoid infecting others.• If you have a fever, cough and difficulty breathing, seek medical attention immediately. Call by telephone first, if you can and follow the directions of your local health authority.• Keep up to date on the latest information from trusted sources, such as WHO or your local and national health authorities.
Is temperature screening effective to detect the coronavirus disease
See full answerTemperature screening alone, at exit or entry, is not an effective way to stop international spread, since infected individuals may be in incubation period, may not express apparent symptoms early on in the course of the disease, or may dissimulate fever through the use of antipyretics; in addition, such measures require substantial investments for what may bear little benefits. It is more effective to provide prevention recommendation messages to travellers and to collect health declarations at arrival, with travellers’ contact details, to allow for a proper risk assessment and a possible contact tracing of incoming travellers.
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.
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.
What are the factors that can determine transmission risk of COVID-19
Factors that determine transmission risk include whether a virus is still replication-competent, whether the patient has symptoms, such as a cough, which can spread infectious droplets, and the behavior and environmental factors associated with the infected individual.
Can COVID-19 spread in hot and humid climates
See full answerFrom 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. Studies suggest that coronaviruses (including preliminary information on the COVID-19 virus) may persist on surfaces for a few hours or up to several days.
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.
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 the coronavirus disease transmitted by direct contact
The virus is transmitted through direct contact with respiratory droplets of an infected person (generated through coughing and sneezing). Individuals can also be infected from and touching surfaces contaminated with the virus and touching their face (e.g., eyes, nose, mouth).
Can the COVID-19 survive in drinking water
Currently, there is no evidence about the survival of the COVID-19 virus in drinking-water or sewage.
Will climate change make COVID-19 worse
There is no evidence of a direct connection between climate change and the emergence or transmission of COVID-19 disease. As the disease is now well established in the human population, efforts should focus on reducing transmission and treating patients.
How can you protect yourself and others from COVID-19
clean hands regularly, prevent droplets from spreading (wearing masks, covering coughs and sneezes), keep at least one metre apart, limit time in enclosed or crowded spaces, clean frequently touched objects and surfaces, and respond appropriately if experiencing COVID-19-like symptoms.
Does COVID-19 survive in sewage
While there is no evidence to date about survival of the COVID-19 virus in water or sewage, the virus is likely to become inactivated significantly faster than non-enveloped human enteric viruses with known waterborne transmission (such as adenoviruses, norovirus, rotavirus and hepatitis A).
Can smoking waterpipes spread the coronavirus disease
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 is the main source of COVID-19 transmission
Current evidence suggests that SARS-CoV-2, the virus that causes COVID-19, is predominantly spread from person-to-person. Understanding how, when and in what types of settings SARS-CoV-2 spreads is critical to develop effective public health and infection prevention and control measures to break chains of transmission.
Does the virus that causes COVID-19 survive on porous surfaces
As a rule of thumb, the virus dies faster on porous surfaces than on non-porous surfaces. However, this rule is not absolute, and of the many surfaces tested, two with the longest survival times are N95 respirator masks and surgical masks, both of which are considered porous surfaces.
What is the minimum distance to be kept from each other to avoid COVID-19
Be a hero and break the chain of COVID-19 transmission by practicing physical distancing. This means we keep a distance of at least 1m from each other and avoid spending time in crowded places or in groups.
Which is the official name of the coronavirus disease
The final name of the disease will be provided by the International Classification of Diseases (ICD). WHO is also proposing ‘2019-nCoV’ as an interim name of the virus. The final decision on the official name of the virus will be made by the International Committee on Taxonomy of Viruses.
How does COVID-19 spread
• Current evidence suggests that the virus spreads mainly between people who are in close contact with each other, typically within 1 metre (short-range). A person can be infected when aerosols or droplets containing the virus are inhaled or come directly into contact with the eyes, nose, or mouth.
