~ Traveller's Diarrhoea ~

·  Very common problem for travellers

COVID-19 (aka Coronavirus)

§ COVID-19 is from a virus family that can cause illness ranging from a mild common cold to severe chest infection

§ The virus causes illness in the lower respiratory tract

§ It can be similar to the common cold and be very mild with a headache and runny nose

§ Other symptoms include, but are not exclusive of, cough, fever and breathing difficulties

§ In severe cases, such as with the medically vulnerable, it can lead to pneumonia and serious complications. There have been reports of individuals being mildly ill and then rapidly becoming unwell

§ It is spread through saliva and respiratory droplets - when a person coughs or sneezes or kisses another

§ It is spread easily through close contact

§ Currently the incubation period to when individuals become unwell is between 2 and 14 days or more after infection

§ Not yet preventable by vaccine

Dengue Fever

§  Causes high fever, severe headaches, eye pain, body aches, vomiting, diarrhoea and flushing of the skin

§     1 - 2 weeks of being severely unwell with flu like illness

Hepatitis A

§     A seriously debilitating disease lasting 3 months or longer
