Viral transmitted from one host to another via horizontal transmission and vertical transmission.
Vertical transmission: transfer of virus from mother to fetus/baby. The virus able to cross the placenta and multiply in the fetus. one good example of vertical transmission is Rubella virus which results in death of fetus or congenital Rubella syndrome (CRS).
Horizontal transmission: transmission of virus between different individuals. This type transmission takes place during sexual activity, needle sharing, exchange of saliva by mouth, arthropod biting, inhalation of aerosol generated (talking, coughing, sneezing) by infected person and ingestion of contaminated food/water.
Viral Pneumonia is transmitted from one person to another. It an acute infection and it is an airborne transmitted virus.
STIs (sexually transmitted infections) are infections transmitted through sexual contact, such as gonorrhea and chlamydia, and can be bacterial, viral, or parasitic. BBVs (bloodborne viruses) are infections transmitted through blood-to-blood contact, such as HIV and hepatitis B and C, and can be transmitted through sharing needles or other equipment that may have blood on them. While STIs are primarily transmitted through sexual activity, BBVs can be transmitted through various means involving blood exposure.
Antibiotics can cure almost all bacterial infections. There are a few drugs that can treat viral infections. Many viral infections can be prevented by vaccinations. Many viral infections do not have a cure.
Viral infections have not been cured. Bacterial infections usually can be.
Both bacterial infections and viral infections can be contagious or not contagious. Some viral infections are not spread from human to human or are only rarely spread that way. TB is a contagious bacterial infection.

Other viral infections may also strike the patient, including croup, bronchitis, laryngitis, or viral pneumonia.
Fungal infections are typically not considered communicable diseases in the same way as viral or bacterial infections. They are usually not spread through casual contact, but can sometimes be transmitted through close and direct contact with infected individuals or contaminated environments. Most fungal infections are not highly contagious and are not easily transmitted between people.

Viral Infections are diagnosed by the presence of the immune systems production of antibodies, viral fighting cells produced specifically for that specific virus.
Viral infections can be spread through direct contact, such as touching an infected person or surface. They are also transmitted via respiratory droplets when an infected person coughs or sneezes. Additionally, some viruses can spread through contaminated food or water, leading to gastrointestinal illnesses.
