Why is healthy eating important for the immune system, especially during the COVID-19 pandemic?

What are some of the ways I can I protect myself from getting infected with COVID-19?

What can I do to cope with the effects of COVID-19 quarantine?

Sedentary behaviour and low levels of physical activity can have negative effects on the health, well-being and quality of life of individuals. Self-quarantine can also cause additional stress and challenge the mental health of citizens.

Physical activity and relaxation techniques can be valuable tools to help you remain calm and continue to protect your health during this time. WHO recommends 150 minutes of moderate-intensity or 75 minutes of vigorous-intensity physical activity per week, or a combination of both.

• The disinfectant and its concentration should be carefully selected to avoid damaging surfaces

• Avoid combining disinfectants, such as bleach and ammonia, since mixtures can cause
respiratory irritation and release potentially fatal gases.
• Keep children, pets and other people away during the application of the product until it is dry and

In non-health care settings, sodium hypochlorite (bleach / chlorine) may be used at a recommended concentration of 0.1% or 1,000ppm (1 part of 5% strength household bleach to 49 parts of water). Alcohol at 70-90% can also be used for surface disinfection.

Surfaces must be cleaned with water and soap or a detergent first to remove dirt, followed by disinfection. Cleaning should always start from the least soiled (cleanest) area to the most soiled (dirtiest) area in order to not spread the dirty to areas that are less soiled.

Is the coronavirus pandemic affecting our mental health?

As the coronavirus pandemic rapidly sweeps across the world, it is inducing a considerable degree of fear, worry and concern in the population at large and among certain groups in particular, such as older adults, care providers and people with underlying health conditions.

In public mental health terms, the main psychological impact to date is elevated rates of stress or anxiety. But as new measures and impacts are introduced – especially quarantine and its effects on many people’s usual activities, routines or livelihoods – levels of loneliness, depression, harmful alcohol and drug use, and self-harm or suicidal behaviour are also expected to rise.
