There are certain things to keep in mind if you are worried about keeping your health in Pakistan. One thing to note is that you should be wary of more than diseases for this area: Mother Nature has other perilous agents here that may well threaten your safety if you are not prepared for or aware of them. To be precise, Pakistan experiences a serious monsoon season that has seen large parts of the country flooded in past years, with examples like the 2010 floods bringing to light just how dangerous the situation can be. In 2010, over 1,700 Pakistanis were killed and several million displaced, all due to rains that lasted only 4 days in total.
Clearly, the first step to preserving one’s health during travels is to be familiar with seasonal risks and time one’s trip to reduce the statistical possibility of encountering perils like monsoons. For Pakistan, this means avoiding the months of June to September in particular and staying away from October to November as well if possible. These are the rainy months, the monsoon seasons of the country when problems like flooding are more likely. The situation at this time is compounded by the fact that swelling floodwaters and pools of stagnant water provide the perfect breeding place for one of the biggest dangers to your health here: the mosquitoes.
Dengue is a danger at this time, so it is strongly advised to bring insect repellent during your trip, especially if you intend to stay in the Punjab area. Another ailment that is fairly common is typhoid fever, along with hepatitis of the A and E strains. Diarrhea is also seen here regularly, and foreigners need to take great care with what they eat so as to avoid it. Street food is obviously suspect as a result, and restaurants with low turnover and which look rather run-down are to be considered unwise selections for the wary tourist too. Yet the biggest concern here may not even be food: it could well be water.
It is advised that people travelling in Pakistan prefer bottled water for drinking and avoid tap water as much as possible. The difficulty, though, is that tap water is not that easily avoided. Most of the ice used for cool drinks in restaurants and small eateries is in fact frozen tap water, which would make your choice of a bottled or canned drink moot if ice is served in your glass. It would be wiser to avoid the ice altogether if you can and simply opt to drink the beverage straight from its bottle or can in such cases.
Finally, you can preserve your health in Pakistan by being sensible. If you have medication that you need to take regularly or which is difficult to procure in other countries, be certain to bring it with you just to be safe. Avoid potentially compromising situations or areas that may hold some peril to the foreigner (like the so-called sensitive or restricted areas) and keep an eye on the travel advisories.
