As COVID-19 sweeps through almost all corners of the world and infects thousands of people, governments and international health authorities are trying to stem its progress through medical intervention and travel restrictions.

The World Health Organization (WHO) has raised its assessment of the risk of the disease spreading to "very high".

Here are some of the measures the WHO says that one should take to safeguard against the virus.

Reduce risk of infection

The virus is mainly transmitted through contact with respiratory droplets expelled through coughing. Some basic hygiene habits can go a long way in protecting oneself from COVID-19.

- Regularly wash your hands with soap and water or alcohol-based sanitizers.

- Maintain distance from people who appear to be suffering from flu, especially when coughing or sneezing.

- Avoid touching eyes, nose and mouth.

- Practice good respiratory hygiene like using a tissue to cover your mouth when coughing or sneezing. Discard used tissues immediately.

- Stay abreast of the latest developments about COVID-19 and guidelines issued by national and health bodies or employer.

Feeling unwell

- In the event of illness and suffering from fever, cough and difficulty breathing, seek medical help. These symptoms may not necessarily indicate COVID-19. It could be common cold or flu.

- Some other symptoms are aches and pains, nasal congestion, runny nose, sore throat or diarrhoea.

- Avoid contact with others and visits to medical facilities and follow directions of the local health authority.

- Self-isolate and make sure all used items like utensils and cutlery are kept separate.

- If experiencing shortness of breath contact the doctor as soon as possible.

- Travel in a safe manner to the appropriate health facility as directed by medical specialists.

Traveling to or returning from COVID-19 affected areas or country

National and state governments have issued a series of advisories against all non-essential travel to regions or countries in the grip of an outbreak.

People returning from COVID-19 hotspots have been urged to quarantine themselves for two weeks in order to shield friends and family and the general public.

In case of feeling unwell, seek medical advice without delay and follow the instructions of medical staff. Tell them about recent travel or contact with travelers.
