VIRUSES AND TYPES:

viruses are the causative agents of many diseases. Once reside in human body as a result forms thousands of copies quickly. Different kinds of viruses are present but some jumped from animals to humans and claimed thousands of lives. For some viral diseases vaccines and anti viral drugs are present so that victims can recover. Still there are some families of virus that have serious threat to health as there are not the ways to combat them.

Some of the worst kinds of viruses are given below:

  • Marburg virus
  • Ebola virus
  • Rabies virus
  • Spanish flu
  • HIV virus
  • Dengue virus

EBOLA VIRUS:

Ebola virus are highly contagious virus because spread through blood contact or other body fluids it was recognized in Republic of Sudan and Congo found near river Ebola in non primates and pigs in 1976 it is a rare but a deadly virus it damage immune system and several organs it causes fever, body aches, diarrhea and sometimes internal and external bleeding it prevent cells from making proteins and damage the blood clotting factors and ultimately destroys immune system.

SYMPTOMS OF EBOLA VIRUS:
Human Viruses

Human Viruses
  • fever                                stomach discomfort
  • headache                        decreased appetite
  • weakness                        muscle discomfort
  • diarrhea                           hair loss
DIAGNOSIS OF EBOLA VIRUS:
  • virus isolation
  • immune chemistry testing
  • IgM and IgG antibodies
TREATMENT OF EBOLA VIRUS:
  • Providing fluids and electrolytes
  • Offering oxygen therapy
  • Medication to maintain BP

DENGUE VIRUS:


Virus first identified in 1950’s in Phillipine and Thailand and spread in tropical and sub tropical regions of the world dengue fever is painful debilitating mosquito borne disease and the dengue virus is closely related to the virus that cause yellow fever mosquitoes are the carrier of disease and is more likely to spread in summers according to world health organization about 50-100 million get sick each year by dengue but not as severe as other viruses patients can suffer from hemorrhagic fever if left untreated causes 20% deaths 

Symptoms of Dengue Virus:

  • high fever                     muscle pain
  • head ache                    rashes
  • nausea                         diarrhea
  • vomiting                        bleeding gums

Diagnosis of Dengue Virus:

  • Antibody detection         RNA detection
  • Antigen detection           Viral isolation

Treatment of Dengue Virus:

In 2019 the FDA, approved a vaccine called Dengvaxia that somehow help prevent the occurrence of disease

MALARIA VIRUS:

Malaria is a life threatening disease because typically transmitted through bite of an infected anopheles mosquito. When this mosquito bites you the parasite is released into your bloodstream. Once the virus enters your body it travels to liver and mature there, then enters blood stream and destroys red blood cells. Within 48-72 hours parasites residing in red blood cells multiply as a result causing infected cells to burst. It can be transmitted from mother to child during birth so also known as congenital malaria.

CAUSES OF MALARIA VIRUS:
  • organ transplant
  • transfusion
  • use of shared syringes
SYMPTOMS OF MALARIA VIRUS:
  • high fever                           anemia 
  • sweating                             vomiting
  • abdominal pain                   muscle pain
COMPLICATIONS OF MALARIA VIRUS:
  • pulmonary edema
  • kidney failure
  • liver failure
  • low blood sugar
TREATMENT OF MALARIA VIRUS:

There is no vaccine available yet to prevent malaria. You may be prescribed medications to prevent disease but make sure the use of mosquito net and bugs spray.

RABIES VIRUS:

Rabies was a serious problem in India as well as several parts of Africa. The disease spread as a result of the biting of an infected animal. The vaccine was introduced in 1920 But rabies destroys brain it is a worst disease. According to Muhlberger; we have a vaccine against rabies and antibodies as well so if someone gets infected by rabid animal he/she should take care and be treated but if you do not get proper treatment there is 100% possibility you will die.

HIV VIRUS:


It is the deadliest virus of all present today. HIV is the biggest killer. About 32 million people expired since early 1980’s. When it was first recognized till now. Though Anti viral drugs are present which may extend the severe symptoms of HIV. Ultimately it results in death in Africans. 1 out of every 25 is found to be HIV positive.

MARBURG VIRUS:

Marburg virus was identified in 1967 As It was associated to infected green monkeys and certain bats so called as zoonotic infections (transmitted from animals to humans). In Uganda two large outbreaks that occur in Germany as well as Belgrade in 1967. Once an individual is infected virus can spread from person to person.

Causes of Marburg Virus:

It can spread via direct contact of blood as well as other secretions from patients. Its symptoms include jaundice, severe weight loss, liver failure and as a result it caused hemorrhagic fever. Infected people suffer from high fever and massive bleeding throughout the body followed by organ failure, shock and collapse of circulatory system and eventually death. Mortality rate in its first outbreak was 25% according to world health organization.

Treatment of Marburg Virus:

Specific treatment for the virus is not known but the patient was treated in ICU. So that his/her electrolyte balance and lost blood was replaced there. Maintaining a good oxygen supply though there are no home remedies to treat Marburg virus.

SPANISH FLU VIRUS:

Pandemic flu occurred in 1918. Outbreak starting from January 1918 to December 1920. It was first observed in Haskell country this virus infected about quarter of world’s population as a result At that time it killed 50-100 million worldwide. Spanish flu killed people with deadly speed for example people woke up sick in morning and died on their way to work. Its descendants can still be found in pigs. When an infected person sneezes or cough more than half a million virus particles can spread to those nearby.
