If you develop diarrhoea, nausea, vomiting, painful stomach cramps, with or without fever, it is a safe bet you’ve got acute infectious gastroenteritis or ‘gastro’.
Gastro comes under the term ‘traveller’s diarrhoea’ or, more colourfully, Pharaoh’s Curse, Bali Belly, or Montezuma’s Revenge (depending on where you encounter it).
Traveller’s diarrhoea (TD) is a very common travel complaint: half of all travellers visiting a developing country for a 2-week stay will experience it to some degree, according to the experts at the US Centres for Disease Control and Prevention (CDC).
Whether your symptoms are mild or severe, how effectively you treat them will usually determine how quickly you recover. More on how to treat TD and when to use ‘stopper’ drugs and antibiotics later in this article.
As your appetite returns, it’s just as important that you eat and drink the right things to help your recovery.

Everyone’s heard a horror story of someone who has come a cropper over travel insurance.
They either don’t have insurance only to get sick/injured/ripped off overseas and their parents/family/friends had to sell a kidney to get them treated and brought home.
Okay, not a kidney, but you get the idea. It can turn into a very expensive nightmare.
Then there are those who are insured and make a claim only to get knocked back because of some obscure clause buried in the policy’s ‘fine print’.
These often-tragic tales become the stuff of travel urban legends, swapped in hushed tones by travellers who fervently hope that they’ll never add their own unhappy chapter.
The Australian government’s smartraveller website has many such stories. The altered names barely disguise the physical and financial pain visited on each luckless traveller and their families when holidays go wrong.

Could condoms help protect Australian babies from the dangers of the mosquito-borne Zika virus?
The answer’s ‘yes’.
Let me explain why…
Much has been written recently about the suspected link between the mosquito-borne Zika virus and a sudden spike in microcephaly in infants born to women infected during pregnancy in Latin America.
Experts from around the globe are studying the phenomenon. However, it’s looking increasingly likely that the virus is the cause of the condition, which results in the child being born with a smaller skull and brain, leaving them with lifelong neurological damage.
But, it’s not only women already pregnant or those planning to conceive who should either avoid travel to Zika-infected regions – which now includes much of the Caribbean, the Americas, and parts of SE Asia, the Pacific and Africa – or, if they do go, take measures to prevent being bitten by mosquitoes.
Their male partners also should be aware of the potential threat Zika could pose.
And, that’s where condoms come in.

If you were to examine the surface of some types of fruit and vegetables through a microscope you’d see a maze of cracks and crevices.
Invisible to the naked eye, these tiny trenches are perfect places for germs to become trapped and multiply.
We’ve seen just how effective contaminated salad vegetables can be at causing food poisoning over the past week. As of Monday, 92 people had been made ill by salmonella across Australia after eating pre-packaged leafy salad mixes, with more expected.
Although the outbreak is still under investigation, food industry experts believe it’s linked to either contaminated fertiliser (from chickens), or to the water that was used to irrigate the crop or wash the lettuce before it was bagged at Tripod Farms in Victoria.
Salmonella is an increasingly common cause of food poisoning in Australia. There were just over 17,000 lab-confirmed cases here last year – the highest tally in 25 years. Many milder cases are not recorded at all.
Worryingly, strains of the bacterium are becoming increasingly resistant to antibiotics.

You may have seen them worn in nightclubs or at parties – colourful contact lenses. Cat’s eyes, snake eyes, all-white zombie eyes… the variety is endless.
Scores of websites offer these cheap, one-size-fits-all coloured contacts.
While they may seem harmless – a bit of eye-catching fun – the sale of contact lenses without a prescription is illegal in most Australian states.
But, illegal or prescribed, using contact lens can result in serious infections – even blindness in rare cases – if they’re not inserted, cleaned, or stored correctly and hygienically.
Contact lenses are actually medical devices. Although they’re a discrete substitute for spectacles, the important difference is that they come into direct contact with your eyes.
Ask anyone who currently wears contacts (or has worn them in the past). They’ll tell you that contacts can be just as problematic as they are convenient – especially during a trip overseas.

Thousands of Australian citizens and residents of Asian heritage will journey ‘home’ to their country of origin in coming weeks to celebrate the Lunar New Year.
In China, Lunar or Chinese New Year is a major holiday and its many regional neighbours – especially those with significant Chinese populations – celebrate the event on or around the same date as China. This year – the year of the monkey – it falls on February 8.
But, this annual cultural and religious event isn’t so much a single night filled with fireworks and fun as a festival extending over several weeks to herald the northern hemisphere spring.
The homecoming provides an opportunity to reunite with far-flung family and friends. During their stay the visitors from ‘Down Under’ often live in family homes in metro and rural areas.
But, the Lunar New Year celebrations can have serious health implications for both travellers and the wider Australian community.
Studies have shown that people travelling to visit friends and relatives (collectively referred to as ‘VFRs’ by travel medicine experts) are at much higher risk of illness than any other category of traveller, particularly if they visit a developing country.
