ABSTRACTOn September 1, 2019, Hurricane Dorian made landfall as a category 5 hurricane on Great Abaco Island, Bahamas. Hurricane Dorian matched the “Labor Day” hurricane of 1935 as the strongest recorded Atlantic hurricane to make landfall with maximum sustained winds of 185 miles/h.1 At the request of the Government of the Bahamas, Team Rubicon activated a World Health Organization Type 1 Mobile Emergency Medical Team and responded to Great Abaco Island. The team provided medical care and reconnaissance of medical clinics on the island and surrounding cays…

The ArgumentAdvances in genetic research make it possible to identify carriers of a growing number of genetic diseases. The World Health Organization (WHO) published several preconditions for community carrier screening. This paper aims to present some of the dilemmas about screening in Israel and the difficulties in following the WHO's helpful criteria.


The World Health Organization (W.H.O.), since its inception in 1947, has given close attention to influenza. In its early years W.H.O. laid the foundations of its present network of over 100 national influenza centres and collaborating laboratories which today constitute the backbone of its influenza activities. The activities of the network include the isolation and characterization of influenza strains and the early notification of any changes in surface antigens, the preparation of reference reagents, standardization of diagnostic procedures, formulation of requirements for vaccines, training, and collaboration in research. The efficacy of the network has been proved in the 1957, 1968 and 1977 epidemics. Collaborative research organized by W.H.O. has made important contributions to our understanding of the epidemiology of influenza, including the possible role of lower animals as the origin of some pandemic strains. The latter subject is briefly discussed.

The present study was carried out to determine the phytochemical and anti nutritional composition of some selected edible mushrooms collected in Ekiti State, Nigeria such as Pleurotus sajor-caju, Termitomyces robustus, Lentinus squarosullus, Termitomyces microcarpous, Termitomyces clypeatus, Lentinus tuber-regium and Polyporus sp. The results of phytochemical analyses revealed the presence of phytochemicals such as alkaloids (0.03-0.17%), saponin (0.03-0.12%), total phenols (0.12-4.32%), flavonoids (0.20-6.04%) and tannins (0.04-2.60%). The least concentration of all the phytochemicals was found in Polyporus sp. Results of anti nutrient screening revealed the presence of phytate (0.17-0.34mg/g), oxalate (1.87-4.04mg/g) and cyanide (0.05-0.27mg/g). Furthermore, results revealed significant differences in the phytochemical as well as anti nutritional composition of the mushrooms though some species had similar compositions. The obtained values of phytochemicals and anti nutrients were significantly lower in all the mushroom species compared to their toxic levels according to World Health Organization stipulated safe limits. Thus, the study suggests that all the mushroom species are very safe for consumption while the presence of alkaloids, saponins, phenols and flavonoids indicate medicinal potentials. Hence, screening and characterization of the secondary metabolites are required.
