Air conditioning may be the main route of transmission of the virus

The main routes of transmission of new coronaviruses are droplets, contact transmission, and fecal transmission. When in a sealed environment, droplets with the virus can be transmitted through the airstream brought by cold air, and even fly farther. According to experts, the characteristics of the new coronavirus pneumonia are similar to those of the SARS virus in 2003, which can make the virus inactive or even extinct when it reaches a high temperature of 60 degrees or above.

Route of transmission The severity of the symptoms of human infection with the new coronavirus depends on the type of virus and the immune level of the human body. Fever, cough, shortness of breath, or dyspnea are common. In more severe cases, it can cause nasal respiratory distress syndrome. Toxic shock, etc., can cause patient death. The new coronavirus can be transmitted from person to person. Transmission usually occurs in homes, workplaces, densely populated areas or hospitals. There is currently no vaccine against the new coronavirus, and new diseases may take longer to develop a vaccine. For the time being, there is no effective treatment for diseases caused by new coronavirus infections, and symptomatic supportive treatment is the main clinical treatment.

The typical symptoms are fever, fatigue, and cough. There are small number of patients with symptoms such as nasal congestion, runny nose, ache, and diarrhea.  Most of the patients often have difficulty breathing and / or hypotensive disease one week after the onset of symptoms Severe cases progress rapidly to acute respiratory hypersyndromes, podogenic shock, difficult to correct metabolic acidosis and coagulopathy.
