    World Health Organization (WHO) measles surveillance data report a reduction in cases of measles globally from 67,524 cases in 2015 to 16,846 in 2016, and a reduction in deaths from 546,800 to 114,900 during period of 2000-14. Pakistan is among the five nations where almost a million children did not receive their first dose of measles vaccination, and outbreaks of the disease resulted in 4386 cases in 2011, 14,687 cases in 2012 with 310 deaths. In 2013, about 25,401 cases of measles were reported and 321 affected children died. The measles vaccination coverage is very low in Pakistan for both 1st dose and booster dose. To prevent outbreaks of measles in Pakistan a national vaccination program should be launched side by side with a polio eradication program in each district and township and a campaign should be launched to educate parents on measles vaccination for childrens to reduce the measles case fatality rate.

    Ecotourism can function as a powerful tool for species conservation. However, a significant proportion of travelers at wildlife sanctuaries may be ill and potentially infectious, creating unnecessary risk of pathogen transmission to wildlife.

    International travel may be associated with the risk of a wide range of infectious diseases. This study was designed to obtain information on the health problems among international travellers from a subtropical region to the neighbouring tropical, subtropical, and temperate regions. Health problems among international travellers from Taiwan to the Philippines, Malaysia, Indonesia, Singapore, Vietnam, Thailand (tropical group), Hong Kong, Macao, China and Japan (non-tropical group) were surveyed through the telephone. Of 649 travellers surveyed, 8.2% had one or more health problems and insect bite (3.4%) and coughing or sore throats (3.2%) were the most important symptoms. The rate of coughing or sore throats was significantly higher among those returned from the non-tropical regions. However, no associations were found between health problems and the demographic factors, travel style or travelling duration of travel.

    Each year millions of travelers undertake long distance flights over one or more continents. These multiple time zone flights produce a constellation of symptoms known as jet lag. Familiar to almost every intercontinental traveler is the experience of fatigue upon arrival in a new time zone, but almost as problematic are a number of other jet lag symptoms. These include reduced alertness, nighttime insomnia, loss of appetite, depressed mood, poor psychomotor coordination and reduced cognitive skills, all symptoms which are closely affected by both the length and direction of travel. The most important jet lag symptoms are due to disruptions to the body's sleep/wake cycle. Clinical and pathophysiological studies also indicate that jet lag can exacerbate existing affective disorders. It has been suggested that dysregulation of melatonin secretion and occurrence of circadian rhythm disturbances may be the common links which underlie jet lag and affective disorders. Largely because of its regulatory effects on the circadian system, melatonin has proven to be highly effective for treating the range of symptoms that accompany transmeridian air travel. Additionally, it has been found to be of value in treating mood disorders like seasonal affective disorder. Melatonin acts on MT(1) and MT(2) melatonin receptors located in the hypothalamic suprachiasmatic nuclei, the site of the body's master circadian clock. Melatonin resets disturbed circadian rhythms and promotes sleep in jet lag and other circadian rhythm sleep disorders, including delayed sleep phase syndrome and shift-work disorder. Although post-flight melatonin administration works efficiently in transmeridian flights across less than 7-8 times zones, in the case longer distances, melatonin should be given by 2-3 days in advance to the flight. To deal with the unwanted side effects which usually accompany this pre-departure treatment (acute soporific and sedative effects in times that may not be wanted), the suppression of circadian rhythmicity by covering symmetrically the phase delay and the phase advance portions of the phase response curve for light, together with the administration of melatonin at local bedtime to resynchronize the circadian oscillator, have been proposed. The current view that sleep loss is a major cause of jet lag has focused interest on two recently developed pharmacological agents. Ramelteon and agomelatine are melatonin receptor agonists which, compared to melatonin itself, have a longer half-life and greater affinity for melatonin receptors and consequently are thought to hold promise for treating a variety of circadian disruptions.

    Cutaneous larva migrans is a parasitic skin eruption caused by migration of larvae of various nematodes. Diagnosis of cutaneous larva migrans is currently based on the clinical signs of the creeping eruption. We are investigating a new diagnostic technology called optical coherence tomography (OCT) , which is potentially able to visualize structures in the skin with an 8 microm resolution. This technology could therefore potentially allow rapid, non-invasive, in vivo diagnosis of infestations.

    Dengue fever is endemic in many countries of South East Asia. In spite of the occasional epidemics, dengue maculopathy remains a rare entity.

    High altitude training is regarded as an integral component of modern athletic preparation, especially for endurance sports such as middle and long distance running. It has rapidly achieved popularity among elite endurance athletes and their coaches. Increased hypoxic stress at altitude facilitates key physiological adaptations within the athlete, which in turn may lead to improvements in sea-level athletic performance. Despite much research in this area to date, the exact mechanisms which underlie such improvements remain to be fully elucidated. This review describes the current understanding of physiological adaptation to high altitude training and its implications for athletic performance. It also discusses the rationale and main effects of different training models currently employed to maximise performance. Athletes who travel to altitude for training purposes are at risk of suffering the detrimental effects of altitude. Altitude illness, weight loss, immune suppression and sleep disturbance may serve to limit athletic performance. This review provides an overview of potential problems which an athlete may experience at altitude, and offers specific training recommendations so that these detrimental effects are minimised.

    The Department of Health regulates the designation of yellow fever vaccination centres (YFVCs) in the Republic of Ireland to ensure appropriate standards in the safe, effective use of yellow fever vaccine for overseas travellers. The process of designation of YFVCs is delegated to Directors of Public Health who direct Principal Medical Officers. Variation in implementation of specific criteria for designation exists and no formal follow up inspection is carried out. This survey of all designated YFVCs in the Republic of Ireland aimed to assess compliance with standards to ensure the objectives of the national yellow fever vaccination programme were met.

    Dengue fever is one of the most important arthropod-borne viral diseases of public health significance. It is endemic in most tropical and subtropical parts of the world, many of which are popular tourist destinations. The presence of dengue infection was examined in Iranian patients who were referred to the Arboviruses and Viral Haemorrhagic Fevers Laboratory of the Pasteur Institute of Iran and tested negative for Crimean-Congo Haemorrhagic Fever (CCHF) between 2000 and 2012. Serum samples from these patients were tested for the presence of specific IgG and IgM and viral nucleic acid in blood. Of the 300 sera tested, 15 (5%) were seropositive, and 3 (1%) were both serologically and PCR positive. Of the 15 seropositive cases, 8 (53.3%) had travelled to endemic areas including Malaysia (5, 62.5%), India (2, 25%) and Thailand (1, 12.5%). In contrast, 7 (46.7%) of the cases had not reported travelling abroad. Of these, six cases were from the Sistan and Baluchistan province in southeast Iran and neighbouring Pakistan. Travellers play a key role in the epidemiology of dengue infection in Iran and it is recommended that travellers to endemic areas take precautionary measures to avoid mosquito bites.
