List of group B infectious diseases

Infectious diseases are classified into a variety including group A infectious diseases, group B infectious diseases, and group C infectious diseases. If not detected and effectively isolated, infectious diseases can have severe consequences for sufferer or outbreaks into large outbreaks.

1. What is group B infectious disease?

An infectious disease is a disease that is transmitted directly or indirectly from person or from animal to person, caused by the cause of an infectious disease. The agents of infectious diseases can be viruses, bacteria, parasites and fungi. Group B infectious diseases are dangerous diseases, capable of rapid and potentially fatal transmission.

  • Assym virus disease (Adeno)

A-dyke virus disease is an acute disease with a diverse clinical syndrome, patients are often infected with acute viruses in the upper respiratory tract with the dominant symptom of rhinitis. In special cases, the virus that causes disease in the lower respiratory tract includes: small bronchitis and pneumonia.

  • Virus disease that causes HIV/AIDS (human immuno-depletion syndrome)

HIV infection is divided into 4 stages, depending on related diseases such as weight loss, opportunity infections, malignanty diseases, physical activity levels. The pathogen is caused by the HIV virus that causes immuno-deterioration in humans.


  • Diphtheria

Diphtheria is an acute bacterial infection with a false mesenteritis in the pharynx, almond glands, the pharynx and nose. The disease may appear in the skin or other mucous membranes such as the conjunctivitis of the eyes, genitals. Serious lesions of the disease are mainly caused by bacterial toxins.

  • influenza

Influenza is an acute respiratory viral infection with the usual manifestations of: fever, headache, muscle pain, fatigue, runny nose, sore throat and cough. Cough in influenza is often severe and prolonged, which can be accompanied by gastrointestinal symptoms (nausea, vomiting, diarrhea) especially in children.

The disease usually goes mild, recovering within 2-7 days. In children, older adults, people with chronic diseases or people with immunosmmunity, influenza can be more severe such as otitis, bronchitis, pneumonia, encephalitis and even death.

  • rabies

Rabies is an acute viral infection on the central nervous system. The disease is transmitted from animals to humans by secretion, usually saliva infected with rabies virus. Most cases of rabies exposure are through bites or licks of diseased animals. Sometimes rabies can be infected through contact such as inhalation of a solution or a new organizational transplant infected with the rabies virus. Once there is a rabies, both animals and humans lead to death.

  • Whooping cough

Whooping cough usually begins 1-2 weeks after being transmitted from a child with another whooping cough. The disease on-top resembles symptoms of a cold: Fever, runny nose and cough, then 2 weeks of whooping cough begins. The whooping cough presentes with a persistent cough, many times, does not breathe in time, coughs until a thick mucus is spit out, and then the child breathes vapor into the lungs with a hiss. When coughing, the child's lips and nails are purple because of a lack of air, after which the cough may vomit. Between coughing attacks, the child with whooping cough almost looks healthy. Whooping cough usually runs out after three months or so. Whooping cough is especially dangerous for children under 1 year of age, so early vaccination of the child is required.

  • Pulmonary tuberculosis

Tuberculosis can be seen in all parts of the body such as pleura, lymph nodes, meninges, joints, peri membranes, urinary and urinary systems, intestines … of which pulmonary tuberculosis is the most common (80 – 85%) and is the primary source of transmission.

  • Diseases caused by human swine sysc singular disease

Swine streptococcus suis is caused by swine streptococcus and can be transmitted to humans. Although S.suis infection is rare in humans, people are still at risk of infection and disease when exposed to sick pigs or products from sick pigs. Manifestations of the disease are: meningitis, hemorrhage, pneumonia, myocarditis and arthritis. Severely ill people can die from bacterial toxins that cause bacterial shock, endoratitis, multi-organ failure, sepsis … Mortality can be up to 7%.

  • Erysentery

Amoeba entery is an intestinal infection, which can be in an acute, acute or chronic form. Lesions can be in the extra-intestinal position (liver, pleural, etc.)

  • Erysentery

Erythrobial entery is an acute intestinal infection caused by Shigella bacteria. The disease has a variety of manifestations (25% have apparent entery syndrome, 25% of asymptotic infections, most cases have only mild diarrhea, a few have chronic progress).


  • Mesm disease

Mumps disease is caused by the viral Mumps virus, which belongs to the Rubulavirus breed and the family Paramyxoviridae. The disease is widely distributed globally but the incidence is higher in crowded areas, low life, cold climates.

  • Dengue, Dengue

Dengue virus (Dengue virus) causes Dengue fever/Dengue hemorrhagic fever of flavivirus variety, Flaviviridae family, consisting of 4 types of serum: D1, D2, D3, D4. All 4 tubes can be encountered in Vietnam and alternately cause epidemics.

  • Malaria

The pathogen is the malaria parasite (Plasmodium). There are 4 types of parasites in humans: P.malariae, P.vivax, P.falciparum and P.ovale. In Vietnam, there are 3 types: P. falciparum, P.vivax and P.malariae. There are 4 methods of transmission: Transmitted by mosquitoes (mainly), due to blood transfusions infected with malaria parasites, transmitted by the mother to the child through the damaged placenta, by injecting blood-stained syringes with parasites.

  • Typhal fever

Typhal fever consists of 3 main diseases: lice-stained typhuse, louse or also known as classical typhuse, rat-in-rat typhal, also known as rat fleas local typhuse, and mite-stained typhuse, also known as bush typhal fever.

  • Measles

Measles is an infectious disease, causing widespread epidemics everywhere in the world, especially in the pre-vaccination period. The disease is common in children. Over 90% of people before the age of 20 already have measles, which is very rare. It is estimated that every year about 100 million cases and 6 million people die from measles.

The disease mainly occurs in children under 10 years of age, which can also be encountered in adults as well. Young children, children and adolescents are very susceptible to infection and disease because there are few antibodies.

  • anthrax

Anthroths are acute bacterial infections, which damage the skin, rarely cause damage to the mouth-throat, lower respiratory tract, mediascinal or lesions in the digestive apparatus. The pathogen is bacillus anthracis.

  • Chickenpox

Viral diseases. When spreading the disease from another person, it manifests it 2-3 weeks later.

There are cases of sudden manifestations of fatigue, the appearance of hemorrhagic plaques and even shock. If detected early and actively treated, the mortality rate is only 5-15%.

  • Viral encephalitis

Viral encephalitis is divided into 2 types: the main viral encephalitis and the second viral encephalitis. The second viral encephalitis diseases are complications of measles viruses, mums, influenza, herpes simplex … The main viral encephalitis with pathogenic pathogens are viruses with a natural reservoir, transmitted by insects including: mosquito-borne viral encephalitis and tick-borne viral encephalitis.

  • Jaundice spiral disease

Jaundice spiral disease is a disease transmitted by animals to humans. The disease has a variety of clinical forms from hidden bacterial infections, mild non-jaundice, or non-manifestations of meningitis to typical acute bodies, severe jaundice.
