Viruses

One of the most well known viral diseases is Influenza (flu). Individuals frequently use the name “flu” for almost any type of moderate sickness, like a cold or a stomach virus. While the symptoms are similar to the flu, having a viral infection from the actual flu virus is different. Influenza symptoms are generally more serious compared to symptoms of a cold and the influenza viral infection lasts longer. Catching the flu won’t result in vomiting or diarrhea in adults, in normal situations.

People suffering from Influenza complain of chills, high body temperature, drippy nose, a sore throat, muscle aches, severe throbbing headache, hacking and coughing, lack of strength / tiredness and generally feeling uncomfortable.

The flu changes its characteristics every year, although there is always a dominant strain. One of the most deadly flu strains is H1N1, also known as the swine flu, which caused pandemics around the world and is still showing up today as a dominant strain.

But, within a couple of months from contracting the HIV virus, it is very likely that they will exhibit signs very similar to symptoms of the flu. The HIV symptoms will rapidly grow to include high temperature and fever, extreme headache, fatigue and overall body ache. It is also common to find enlarged lymph nodes that are easy to detect in the neck and groin region.

Hantavirus outbreaks, like the deadly outbreaks common in South America, could be forecast months in advance by using satellite pictures to observe sharp increases in plant-life growth that allow mouse populations to grow unchecked. Researchers are considering this information critical to their monitoring and forecasting of hantavirus and other rodent-borne illnesses globally.

Public illness, coupled with a lacking policy on cleanliness procedures may have allowed an outbreak of norovirus on board a Princess Cruise ship to become more dangerous than it otherwise would have been, and then infected the crew and passengers. Princess Cruise Ship’s policy allows it to clean the ships thoroughly and return them to service. In such cases, passengers are notified of the outbreak, the cleaning and advised of protective measures to help prevent future outbreaks.

In Mumbai, India scientists have discovered a discomforting increase in cases of drug-resistant Tuberculosis, and the latest frightening news is indicating that 100 to 200 million people may be carrying one of two deadly microbes – ha-MRSA and ca-MRSA – that happen to be resistant to virtually any antibiotic, causing near panic regarding the chance of outbreak.

Vibriosis is triggered by bacterial infection from the Vibrio genus, typically Vibrio parahemolyticus or Vibrio vulnificus. Diarrhea often accompanies Vibrio bacteria along with more serious skin infections, and blood infections. Vibrio parahemolyticus is a mostly harmless infection that commonly causes diarrhea, however the Vibrio vulnificus infection, while rare, may contribute to blood poisoning and fatality on many occasions.
