Strep Throat is an infectious bacterial disease that is contagious and is caused by the inflammation and swelling in the lining of the mucus membranes in the back of the throat and the tonsils. The throat gets a burning sensation and a severe irritation, causing a sudden, severe sore throat. Strep throat generally affects the throat and tonsils and makes swallowing hard. Sometimes a sore throat is mistaken for strep throat. Sore throats are mostly caused by a viral infection and not the streptococcal bacteria.
Mosquitoes pose a huge health hazard as they spread diseases, such as malaria, dengue fever, yellow fever, chikungunya and encephalitis. This article gives you an overview of some these diseases and some tips on how to protect your child from mosquito borne diseases. 1. Malaria Malaria is a common mosquito-borne disease in India. Malaria can occur all the year around but the number of cases increases during the monsoon season.
Typhoid is a common global bacterial disease spread by the consumption of food or water contaminated with the feces of an infected individual, which consist of the bacterium Salmonella enteric subsp. Enteric serovar Typhi.  The infection has received numerous names, such as stomach fever, abdominal typhus, infant remittent fever, enteric fever, slow fever, nervous fever and phytogenic fever. The term typhoid means "similar to typhus" and initiates from the neuropsychiatric warning sign common to typhoid and typhus.  In spite of this similarity of their names, typhoid fever and typhus are different diseases and are initiated by diverse species of bacteria.
The aforementioned ring forms that are seen within red blood cells can vary significantly and can be easily misinterpreted as Plasmodium falciparum (i.e. a malaria parasite), although the absence of the hemozoin pigment should point to Babesia parasites. And indeed, there are cases described in the literature when the patient was erroneously diagnosed with malaria, which may result in misguided treatment and pose a serious risk to the
1. Overview Dengue, also known as “breakbone fever,” due to the intense pain experienced by some patients, is a mosquito-borne viral illness found throughout the tropics and recognized as a worldwide problem since the 1950s. During the 1960s and 1970s, it progressively increased as a health problem, spreading from its primary location in tropical countries to smaller cities and towns in endemic countries. Nowadays, dengue is considered an emerging disease, with reported cases increasing globally every year, making it the most common arthropod-borne disease in the world. The infection is caused by the dengue virus, transmitted to humans through the bite of the Aedes mosquito.
The manifestations of severe malaria include Cerebral malaria, with abnormal behavior, impairment of consciousness, seizures, coma, or other neurologic abnormalities Severe anemia due to hemolysis (destruction of the red blood cells) Hemoglobinuria (hemoglobin in the urine) due to hemolysis Acute respiratory distress syndrome (ARDS), an inflammatory reaction in the lungs that inhibits oxygen exchange, which may occur even after the parasite counts have decreased in response to treatment Abnormalities in blood coagulation Low blood pressure caused by cardiovascular collapse Acute kidney failure Hyperparasitemia, where more than 5% of the red blood cells are infected by malaria parasites Metabolic acidosis (excessive acidity in the blood and tissue fluids), often in association with hypoglycemia Hypoglycemia (low blood glucose). Hypoglycemia may also occur in pregnant women with uncomplicated malaria, or after treatment with
Introduction: Scrub typhus is an acute febrile mite borne disease caused by Orientia tsutsugamushi which is under-diagnosed in India. Scrub typhus produced considerable morbidity and mortality among the troops in Southeast Asia during World War II. Nevertheless, there has been a significant decline in the incidence of scrub typhus in the later
Introduction Man is living in a quite hostile environment, and badly vulnerable to internal and external enemies. Of these numerous enemies, various kinds of microbial infections are of supreme importance. These microbial infections can be further sub-categorized on the basis of their etiological organisms, mode of transmission and organ system which is mainly affected by the injurious effects of microbial invasion. Dengue fever, also known as a break-bone fever, is one of these lethal microbial infections. Dengue fever is an ancient disease and many centuries ago its very first case was recorded in a Chinese medical encyclopedia in 9921.
In the past century, the world was alarmed by influenza viruses that killed hundreds of thousands. The virus is extremely dangerous due to the fact that it transmits easily through food, air, water or by the contact of skin. The most recent flu pandemic occurred is in 2009 which is known as swine flu H1N1. The term “flu pandemic” can be defined as epidemic of a type of influenza virus that spreads seasonally in an enormous scale around the world. The emergence of problems to a country to brace the consequences of the infectious disease is frightful and need to be closely examined.
