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.
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.

Can COVID-19 be transmitted through water treatment and sewage?
Currently, there is no evidence about the survival of the COVID-19 virus in drinking-water or sewage. The morphology and chemical structure of the COVID-19 virus are similar to those of other human coronaviruses for which there are data about both survival in the environment and effective inactivation measures.
Can masks prevent the transmission of COVID-19?
Do COVID-19 and tuberculosis spread in the same way?
Can ceiling fans improve the circulation of air to reduce transmission of COVID-19?
The use of ceiling fans can improve the circulation of air from outside and avoid pockets of stagnant air forming indoors. However, it is critical to bring in air from outside when using ceiling fans, such as by opening windows.
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.
Is coughing a common symptom of COVID-19?
Coughing is a reasonably common symptom of COVID-19, affecting more than four in ten (46%) adults who are ill with the disease.
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.
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.
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.
What should staff do if a guest develops symptoms of COVID-19 at an accommodation establishment?
What does pre-symptomatic transmission of COVID-19 mean?
The incubation period for COVID-19, which is the time between exposure to the virus (becoming infected) and symptom onset, is on average 5-6 days, however can be up to 14 days. During this period, also known as the “pre- symptomatic” period, some infected persons can be contagious. Therefore, transmission from a pre-symptomatic case can occur before symptom onset.
Are smokers more vulnerable to contracting COVID-19?
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.
Why should I ventilate indoor spaces during COVID-19?
For COVID-19, it is important to ventilate indoor spaces if someone in your home has the virus as this can help prevent transmission to other household members.
How long do I need to self-isolate if you are a contact of a person who tested positive for COVID-19?

Does smoking increase the risk of serious COVID-19 disease?

Do I need to quarantine at home if someone I live with gets COVID-19?
Stay at home for the full 10 days to avoid putting others at risk. If you develop symptoms while you are isolating, arrange to have a COVID-19 PCR test. If your test result is positive, follow the advice for people with COVID-19 to stay at home and start a further full 10 day isolation period.
What should I focus on to avoid getting infected with COVID-19?
