Infuenza and Patients with Chronic Diseases and Elderly

@#Influenza is a highly contagious viral illness characterized by fever, cough, headache and myalgia. The influenza virus is a segmented ribonucleic acid (RNA) virus that can infect both humans and animals, and the capacity for reassortment when multiple viruses infect the same cell has led – and will continue to lead – to the development of novel pandemic influenza A viruses. The disease is generally self-limiting, although complications and deaths can occur, particularly in children < two years of age, adults >65 years of age, pregnant women, and immunosuppressed individuals. Specific antiviral therapy is available, including oseltamivir in Singapore, and is recommended for severe disease as well as those with higher likelihood for developing complications from influenza. In addition to hand hygiene and respiratory etiquette, antiviral prophylaxis may reduce the impact and burden of influenza in household and institutional settings. However, the primary means for preventing influenza is via annual vaccination in those above the age of two years. The influenza vaccine, while having variable efficacy depending on antigenic matching with circulating viruses each year, is safe and cost-effective at the population level.

Understanding of Malaria and Its Therapeutic Regimens–The Way Forward.

Aim: Malaria is a very serious deadly disease that has attracted the attention of many researchers all over the world. Because a lot of work has been done in the area of malariology, there is need to understand its advance pattern and therapeutic regimens. Methods: Past and recent literatures on malaria were searched for information on history, global situation, classification, biology, pathology, pathogenesis, diagnosis, treatment and control of malaria to assess the progress made so far in the area of malariology. Results: Malaria is an ancient disease recognized by Hippocrates over 2413 years ago, caused by Plasmodium species, first identified by Charles-laveran 123 years ago affect 300–500 millions human worldwide, responsible for 3 deaths in every 30 seconds. The knowledge of classification, biology, pathology, pathogenesis, diagnosis and treatment of malaria is a tremendous achievement towards the control of the disease. Conclusion: But complete elimination of malaria perhaps will still take another time, since lots need to be known about the molecular biology of antigenic shift and drift, nature and mechanisms of action of the parasite toxin, in order to have basis for definite vaccine development. By so doing, radical cure and total eradication of malaria can be achieved.
