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.

Can contact tracing help in controlling the spread of COVID-19?

Yes, when systematically applied, contact tracing will break the chains of transmission, meaning that the virus transmission can be stopped. Contact tracing is thus an essential public health tool for controlling infectious disease outbreaks, such as COVID-19.

How severe is the coronavirus disease?

Most people infected with the COVID-19 virus will experience mild to moderate respiratory illness and recover without requiring special treatment. Older people, and those with underlying medical problems like cardiovascular disease, diabetes, chronic respiratory disease, and cancer are more likely to develop serious illness.

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 are the possible modes of transmission of COVID-19?

Transmission of SARS-CoV-2 can occur through direct, indirect, or close contact with infected people through infected secretions such as saliva and respiratory secretions or their respiratory droplets, which are expelled when an infected person coughs, sneezes, talks or sings.

Can workers remove themselves from work if they believe it’s not safe due to COVID-19?

Workers have the right to remove themselves from any work situation that they have reasonable justification to believe presents an imminent and serious danger to their life or health, and should be protected from any undue consequences as a result of exercising this right.

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.

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.

Can asymptomatic people transmit COVID-19?

Yes, infected people can transmit the virus both when they have symptoms and when they don’t have symptoms. This is why it is important that all people who are infected are identified by testing, isolated, and, depending on the severity of their disease, receive medical care.

How serious is the coronavirus disease?

In the majority of the cases i.e. 80% will exhibit mild symptoms, 14% will have pneumonia, 5% will suffer from septic shock and organ failure (mostly respiratory failure) and in 2% cases it will be fatal.

How long should I self-quarantine if I have been exposed to COVID-19?

Those who may have been exposed to someone with COVID-19 and those who have recently travelled to a country or region with the widespread transmission have been advised to self-quarantine for 14 days from the time of last possible exposure.

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 are some urgent symptoms of COVID-19?

significant difficulty breathing (e.g., can’t catch breath, gasping)
chest pain or pressure
new confusion or difficulty waking up

Is coronavirus airborne?

The Centers for Disease Control and Prevention latest updated guidance about how Covid spreads, emphasizes that the virus can be spread through the air via “very fine droplets and aerosolized particles” from an infected person who is more than 6 feet away.

What to do if you have COVID-19 symptoms?

If you’re experiencing COVID-19 symptoms, contact your local public health authority and isolate yourself at home for 14 days to avoid spreading it to others. Most people with mild symptoms will recover on their own.Adults and children who have mild COVID-19 symptoms are able to stay at home with a caregiver throughout their recovery without needing hospitalization. If you’re a caregiver, follow the advice on how to care for someone with COVID-19 at home.

What does COVID-19 serological testing detect?

Serological tests do not detect the virus itself. Instead, they detect the antibodies produced in response to an infection. Serology tests are also known as antibody tests.
